Use git submodule for buildroot (#1445) 

* Drop buildroot from git repository

Manage buildroot in a separate git repository and use a git submodule
to include it into the HAOS source tree.

This makes it easier to manage changes to buildroot since it can be
managed by git. A buildroot fork repository is being maintained with
the changes we currently have. It makes the buildroot-patches unnecessary
and should make it easier to rebase and upstream changes to buildroot.

* Remove buildroot-patches

Now that buildroot changes are managed in the buildroot fork repository
there is no need to manage patches in a separate directory.

* Initialize git submodule if necessary

* Move build directory to root

This avoids conflict/local modification issues with the buildroot
git submodule.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

Refer to ccache documentation for more details.
These initial settings are applied after ccache has been
compiled.
config BR2_CCACHE_USE_BASEDIR
bool "Use relative paths"
default y
help
Allow ccache to convert absolute paths within the output
directory into relative paths.
During the build, many -I include directives are given with an
absolute path. These absolute paths end up in the hashes that
are computed by ccache. Therefore, when you build from a
different directory, the hash will be different and the cached
object will not be used.
To improve cache performance, set this option to y. This
allows ccache to rewrite absolute paths within the output
directory into relative paths. Note that only paths within the
output directory will be rewritten; therefore, if you change
BR2_HOST_DIR to point outside the output directory and
subsequently move it to a different location, this will lead
to cache misses.
This option has as a result that the debug information in the
object files also has only relative paths. Therefore, make
sure you cd to the build directory before starting gdb. See
the section "COMPILING IN DIFFERENT DIRECTORIES" in the ccache
manual for more information.

intermediary files, and it is very likely that some of these

have by chance been built before.
- Enable top-level parallel build.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.
The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html
To build and use the buildroot stuff, do the following:
1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images
You do not need to be root to build or run buildroot. Have fun!
Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.
Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
If you would like to contribute patches, please read
https://buildroot.org/manual.html#submitting-patches

config BR2_ARM_EABI
bool "EABI"
help
The EABI is currently the standard ARM ABI, which is used in
most projects. It supports both the 'soft' floating point
model (in which floating point instructions are emulated in
software) and the 'softfp' floating point model (in which
floating point instructions are executed using an hardware
floating point unit, but floating point arguments to
functions are passed in integer registers).
The 'softfp' floating point model is link-compatible with
the 'soft' floating point model, i.e you can link a library
built 'soft' with some other code built 'softfp'.
However, passing the floating point arguments in integer
registers is a bit inefficient, so if your ARM processor has
a floating point unit, and you don't have pre-compiled
'soft' or 'softfp' code, using the EABIhf ABI will provide
better floating point performances.
If your processor does not have a floating point unit, then
you must use this ABI.
config BR2_ARM_EABIHF
bool "EABIhf"
depends on BR2_ARM_CPU_HAS_FPU
help
The EABIhf is an extension of EABI which supports the 'hard'
floating point model. This model uses the floating point
unit to execute floating point instructions, and passes
floating point arguments in floating point registers.
It is more efficient than EABI for floating point related
workload. However, it does not allow to link against code
that has been pre-built for the 'soft' or 'softfp' floating
point models.
If your processor has a floating point unit, and you don't
depend on existing pre-compiled code, this option is most
likely the best choice.

The Ingenic XBurst is a MIPS32R2 microprocessor. It has a
bug in the FPU that can generate incorrect results in
certain cases. The problem shows up when you have several
fused madd instructions in sequence with dependant
operands. This requires the -mno-fused-madd compiler option
to be used in order to prevent emitting these instructions.

The aarch64_efi_defconfig allows to build a minimal Linux system that
can boot on all AArch64 servers providing an EFI firmware and ACPI.
Building and booting
====================
$ make aarch64_efi_defconfig
$ make
The file output/images/disk.img is a complete disk image that can be
booted, it includes the grub2 bootloader, Linux kernel and root
filesystem.
Testing under Qemu
==================
This image can also be tested using Qemu:
qemu-system-aarch64 \
-M virt \
-cpu cortex-a57 \
-m 512 \
-nographic \
-bios </path/to/QEMU_EFI.fd> \
-drive file=output/images/disk.img,if=none,format=raw,id=hd0 \
-device virtio-blk-device,drive=hd0 \
-netdev user,id=eth0 \
-device virtio-net-device,netdev=eth0
Note that </path/to/QEMU_EFI.fd> needs to point to a valid aarch64 UEFI
firmware image for qemu.
It may be provided by your distribution as a edk2-aarch64 or AAVMF
package, in path such as /usr/share/edk2/aarch64/QEMU_EFI.fd .

Acme Systems Aria G25
Build instructions
==================
To build an image for the Aria G25 choose the configuration
corresponding to the Aria variant.
For 128MB RAM variant type:
$ make acmesystems_aria_g25_128mb_defconfig
else for 256MB RAM variant type:
$ make acmesystems_aria_g25_256mb_defconfig
To customize the configuration choosed type:
$ make menuconfig
When you are ready to start building Buildroot type:
$ make
How to write the microSD card
=============================
Once the build process is finished you will have an image called
"sdcard.img" in the output/images/ directory.
Write the bootable SD card image "sdcard.img" onto an SD card with
"dd" command:
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Assuming your Aria G25 baseboard has a MicroSD socket, for example
with the Terra baseboard, insert the microSD card into the baseboard
slot and power it.
To get the kernel log messages you can use a DPI cable
(http://www.acmesystems.it/DPI)
You can find additional informations, tutorials and a very
comprehensive documentation on http://www.acmesystems.it/aria.

documentation on http://www.acmesystems.it/arietta.
Build instructions
==================
To build an image for the Arietta G25 choose the configuration
corresponding to the Arietta variant.
For 128MB RAM variant type:
$ make acmesystems_arietta_g25_128mb_defconfig
else for 256MB RAM variant type:
$ make acmesystems_arietta_g25_256mb_defconfig
To customize the configuration chosen type:
$ make menuconfig
When you are ready to start building Buildroot type:
$ make
How to write the microSD card
=============================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX

Creating bootable SD card
=========================
Simply invoke
dd if=output/images/sdcard.img of=/dev/sdX
Where X is your SD card device (not partition)
Booting
=======
Pins 6:8 on P18 selector is used to determine boot device. To boot socrates from
sdcard set these pins to value 0x5 (101b). Remaining pins are used to determine
how to configure FPGA and are not associated with booting into Linux kernel.

Amarula A64 Relic
================
Amarula A64-Relic is an Allwinner A64 based IoT device, which supports:
- Allwinner A64 Cortex-A53
- Mali-400MP2 GPU
- AXP803 PMIC
- 1GB DDR3 RAM
- 8GB eMMC
- AP6330 Wifi/BLE
- MIPI-DSI
- CSI: OV5640 sensor
- USB OTG
- 12V DC power supply
Wiki link:
https://openedev.amarulasolutions.com/display/ODWIKI/Amarual+A64-Relic
Build
=====
$ make amarula_a64_relic_defconfig
$ make
build files at output/images/:
- sunxi-spl.bin
- u-boot.itb
- Image
- sun50i-a64-amarula-relic.dtb
- boot.vfat
- rootfs.ext4
Write eMMC
=========
The board comes with an operating system preloaded on the eMMC.
To replace it with the Buildroot-built system, take the following
steps
1. Connect the board UART with host and open minicom(ttyUSBx/115200N8)
2. Supply 12V DC for power-on the board.
3. Interrupt U-Boot by pressing enter
4. Create GPT partitions
=> mmc dev 1
=> gpt write mmc 1 $partitions
5. Connect the board USB-OTG with USB slot on the host.
6. Initiate fastboot
=> fastboot 0
7. Write images from host onto eMMC using fastboot
$ cd output/images
$ sudo fastboot -i 0x1f3a flash loader1 sunxi-spl.bin
$ sudo fastboot -i 0x1f3a flash loader2 u-boot.itb
$ sudo fastboot -i 0x1f3a flash esp boot.vfat
$ sudo fastboot -i 0x1f3a flash system rootfs.ext4
Update eMMC during Development
==============================
During development, reflashing the entire filesystem image at every
change is time consuming. A useful alternative is to directly access
over USB the filesystem stored on the eMMC, using the USB Mass Storage
capability of U-Boot. To achieve this:
1. Build U-Boot by enabling UMS
$ make uboot-menuconfig
(select CONFIG_CMD_USB_MASS_STORAGE=y)
2. Follow all 6 steps from 'Write eMMC' and mount eMMC on host
=> mmc dev 1
=> ums 0 mmc 1

Subject: [PATCH] include: configs: Increase CONFIG_SYS_BOOTM_LEN to 16MB
The default value of CONFIG_SYS_BOOTM_LEN is 0x800000 i.e, 8MB which
causes board reset because of larger uImage size.
Error log snippet:
Booting using the fdt blob at 0x1f00000
Loading Kernel Image ... Image too large: increase CONFIG_SYS_BOOTM_LEN
Must RESET board to recover
resetting ...

Vyasa RK3288
============
Vyasa is RK3288 based Single board computer with fully supported opensource software.
https://openedev.amarulasolutions.com/display/ODWIKI/Vyasa+RK3288
How to build it
===============
$ make amarula_vyasa_rk3288_defconfig
Then you can edit the build options using
$ make menuconfig
Compile all and build rootfs image:
$ make
Prepare your SDCard
===================
Buildroot generates a ready-to-use SD card image that you can flash directly to
the card. The image will be in output/images/sdcard.img.
You can write this image directly to an SD card device (i.e. /dev/xxx):
$ sudo dd if=output/images/sdcard.img of=/dev/xxx
$ sudo sync
Finally, you can insert the SD card to the Vyasa RK3288 board, close J4 and boot it.

-------------------
The andes_ae3xx_defconfig configuration is a sample configuration with
all that is required to bring the FPGA Development Board:
$ make andes_ae3xx_defconfig
Build everything
----------------
Note: you will need to have access to the network, since Buildroot will
download the packages' sources.
$ make
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
+-- vmlinux
+-- rootfs.cpio
+-- rootfs.tar
How to run it
=============
Run
---
Setup the Console with the rate 38400/8-N-1.

Arcturus uCLS1012A SoM
======================
This tutorial describes how to use the predefined Buildroot
configuration for the Arcturus uCLS101A SoM platform.
Additional information about the uCLS1012A System on Module can be found at
https://www.arcturusnetworks.com/products/ucls1012a
and product support for registered users at
https://www.arcturusnetworks.com/support
Building
--------
Return to the top directory <buildrootdir> and execute the following commands.
make arcturus_ucls1012a_defconfig
make
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
+-- arc-ucls1012a.dtb
+-- Image
+-- part0-000000.itb
+-- rootfs.cpio
+-- rootfs.cpio.gz
+-- rootfs.tar
+-- u-boot.bin
+-- ucls1012a.its
Flashing
--------
You'll need to program the image created by buildroot into the SPI NOR flash.
1. Reboot your module and via the serial console press <escape> to enter the B$
u-boot shell.
From the shell you will need to update four environment variables replacing the
IPv4 IP Address with ones that will work with your network and tftp server.
B$ setenv ipaddr 192.168.1.81
B$ setenv serverip 192.168.1.80
B$ setenv gatewayip 192.168.1.1
B$ setenv netmask 255.255.255.0
B$ saveenv
2. Enable tftp server to serve the <buildrootdir>/output/images/ folder.
3. Program the new U-Boot binary (optional)
If you don't feel confident upgrading your bootloader then don't do it,
it's unnecessary most of the time.
B$ tftp u-boot.bin
B$ run program_uboot
4. Program the ITB image (includes Kernel, DTB and Ramdisk)
B$ tftp part0-000000.itb
B$ run iprogram
5. Booting your new system
Reboot your system by reset command
B$ reset
or
B$ run bootcmd
Good Luck !

B$ cp.b $loadaddr 0xec140000 $filesize
3. Program the DTB
B$ tftp ucp1020.dtb
B$ erase 0xec100000 +$filesize
B$ cp.b $loadaddr 0xec100000 $filesize
4. Program the jffs2 root filesystem
B$ tftp rootfs.jffs2
B$ erase 0xec800000 0xee8fffff
B$ cp.b $loadaddr 0xec800000 $filesize
5. Booting your new system
B$ setenv norboot 'setenv bootargs root=/dev/mtdblock1 rootfstype=jffs2 console=$consoledev,$baudrate;bootm 0xec140000 - 0xec100000'
If you want to set this boot option as default:
B$ setenv bootcmd 'run norboot'
B$ saveenv
...or for a single boot:
B$ run norboot
Good Luck !

This is the support for the ARM Foundation v8 machine emulated by the
ARM software simulator of the AArch64 architecture.
First, one has to download the AArch64 software simulator from:
https://silver.arm.com/download/download.tm?pv=4807186
Then, use the arm_foundationv8_defconfig configuration to build your
Buildroot system.
Finally, boot your system with:
${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/models/Linux64_GCC-6.4/Foundation_Platform \
--image output/images/linux-system.axf \
--block-device output/images/rootfs.ext2 \
--network=nat \
--cores 4
You can get network access from within the simulated environment
by requesting an IP address using DHCP (run the command 'udhcpc').

ARM Juno r1/r0
Intro
=====
These instructions apply to all models of the ARM Juno:
- Juno r0 (does not support PCIe)
- Juno r1 (supports PCIe)
- Juno r2 (Big Cluster with A72)
Buildroot will generate the kernel image, device tree blob, bootloader binaries
and a minimal root filesystem.
How to build it
===============
Configure Buildroot
-------------------
Configuring Buildroot is pretty simple, just execute:
$ make arm_juno_defconfig
Build the rootfs, kernel and DTB
--------------------------------
Note: you will need to have access to the network, since Buildroot will
download the packages' sources.
You may now build your rootfs with:
$ make
(This may take a while)
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
+-- rootfs.tar
+-- juno.dtb (if Juno r0 is used)
+-- juno-r1.dtb (if Juno r1 is used)
+-- juno-r2.dtb (if Juno r2 is used)
+-- Image
+-- bl1.bin
+-- bl2.bin
+-- bl2u.bin
+-- bl31.bin
+-- fip.bin
+-- scp-fw.bin
+-- u-boot.bin
Preparing your rootfs
======================
Format your pen drive as a ext3 filesystem by executing:
$ mkfs.ext3 /dev/<your device>
Preparing your rootfs
======================
Format your pen drive as a ext3 filesystem by executing:
$ mkfs.ext3 /dev/<your device>
Installing your rootfs
======================
After mounting the pen drive please execute the following:
$ sudo tar -xvf output/images/rootfs.tar -C <pen drive mount path>
When completed make sure to unmount the device:
$ umount <pen drive mount path>
Insert the pen drive in one of the ARM Juno' USB type A connectors.
Configure *.dtb in the boot configuration for Juno r0
=====================================================
SITE1/HBI0262B/images.txt
.....
NOR3UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x00C00000 ;Image Flash Address
NOR3FILE: \SOFTWARE\juno.dtb ;Image File Name
NOR3NAME: board.dtb ;Specify Image name to preserve file extension
NOR3LOAD: 00000000 ;Image Load Address
NOR3ENTRY: 00000000 ;Image Entry Point
......
Configure *.dtb in the boot configuration for Juno r1
=====================================================

......
NOR3UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x00C00000 ;Image Flash Address
NOR3FILE: \SOFTWARE\juno-r1.dtb ;Image File Name
NOR3NAME: board.dtb ;Specify target filename to preserve file extension
NOR3LOAD: 00000000 ;Image Load Address
NOR3ENTRY: 00000000 ;Image Entry Point
......
Configure *.dtb in the boot configuration for Juno r2
=====================================================
SITE1/HBI0262D/images.txt
......
NOR3UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x02000000 ;Image Flash Address
NOR3FILE: \SOFTWARE\juno-r2.dtb ;Image File Name
NOR3NAME: board.dtb ;Specify target filename to preserve file extension
NOR3LOAD: 00000000 ;Image Load Address
NOR3ENTRY: 00000000 ;Image Entry Point
......
Installing kernel image and DTB
===============================
1. Connect to the ARM Juno UART0 and execute USB_ON in the terminal
2. Connect a USB cable between your PC and ARM Juno USB type B connector
A mass storage device should appear in your desktop.
3. Open the software/ folder
4. Copy the 'Image' file to software/
5. Copy the 'juno-r1.dtb' (r1), 'juno.dtb' (r0) or juno-r2.dtb (r2) file to software/
6. Copy the bootloader binaries (bl1.bin and fip.bin) to software/
7. Press the red button in the front pannel of ARM Juno
At this time, the board will erase the Flash entry for each new item and
replace it with the lastest ones.

Introduction
============
Armadeus APFxx are Systems On Module (SOM) based on Freescale/NXP i.MX
processors associated with an FPGA (except on APF28). Non volatile
data are stored in on-module NOR or NAND Flash, depending on the
model. These SOM can be used on Armadeus development boards or with
custom docking boards.
Supported platforms
===================
Buildroot currently supports the following Armadeus platforms with the
associated defconfigs:
* APF27 SOM + devt board -> armadeus_apf27_defconfig
* APF51 SOM + devt board -> armadeus_apf51_defconfig
* APF28 SOM + devt board -> armadeus_apf28_defconfig
Vanilla Linux versions are preferred to Freescale's one in these
configurations.
How to build it
===============
Configure Buildroot
-------------------
Let's say you own an APFxx SOM with it's corresponding development
board, all you have to do is:
$ make armadeus_apfxx_defconfig
where "apfxx" is the version of your SOM.
Launch build
------------
$ make
Result of the build
-------------------
When the build is finished, you will end up with:
output/images/
+-- imx**-apfxxdev.dtb [1]
+-- rootfs.tar
+-- rootfs.ubi
+-- rootfs.ubifs
+-- uImage
[1] Only if the kernel version used uses a Device Tree.
Building U-Boot is currently not supported in these configurations.
Installation
============
You will require a serial connection to the board and a TFTP server on
your Host PC. Assuming your server is configured for exporting
/tftpboot/ directory, you will have to copy the generated images to
it:
$ cp output/images/uImage /tftpboot/apfxx-linux.bin
$ cp output/images/*.dtb /tftpboot/
$ cp output/images/rootfs.ubi /tftpboot/apfxx-rootfs.ubi
where "apfxx" is the version of your SOM, as used with _defconfigs.
Then on your serial terminal, all you have to do is:
* interrupt the boot process and access U-Boot console by pressing any
key when booting,
* configure board and server IP addresses with "ipaddr" and "serverip"
environment variables,
* if you want to update kernel:
BIOS > run update_kernel
* if you want to update device tree:
BIOS > run update_dtb
* if you want to update rootfs:
BIOS > run update_rootfs
That's it !

Arrow Avenger96
Intro
=====
This configuration supports the Arrow Avenger96 board:
https://wiki.dh-electronics.com/index.php/Avenger96
How to build
============
$ make avenger96_defconfig
$ make
How to write the microSD card
=============================
WARNING! This will destroy all the card content. Use with care!
Once the build process is finished you will have an image called
"sdcard.img" in the output/images/ directory.
Copy the bootable "sdcard.img" onto an microSD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Boot the board
==============
(1) Configure the boot switches for boot from microsd: 1-0-1
(2) Insert the microSD card in the slot
(3) Plug a serial adapter (beware: 1v8 levels!) to the low speed
expansion connector
(4) Plug in power cable
(5) The system will start, with the console on UART, but also visible
on the screen.

From 8ee2b03039cccf64402a72dea2185d7fe1972729 Mon Sep 17 00:00:00 2001
From: Shyam Saini <shyam.saini@amarulasolutions.com>
Date: Mon, 15 Apr 2019 16:16:16 +0530
Subject: [PATCH] include: configs: Increase CONFIG_SYS_BOOTM_LEN to 16MB
The default value of CONFIG_SYS_BOOTM_LEN is 0x800000 i.e, 8MB which
causes board reset because of larger uImage size.
Error log snippet:
Booting using the fdt blob at 0x1f00000
Loading Kernel Image ... Image too large: increase CONFIG_SYS_BOOTM_LEN
Must RESET board to recover
resetting ...

Tinker RK3288
=============
Tinker Board is a Single Board Computer (SBC) in an ultra-small form
factor that offers class-leading performance while leveraging outstanding
mechanical compatibility.
Tinker link:
https://www.asus.com/in/Single-Board-Computer/Tinker-Board/
Wiki link:
https://openedev.amarulasolutions.com/display/ODWIKI/Tinker+RK3288
How to build it
===============
$ make asus_tinker_rk3288_defconfig
Then you can edit the build options using
$ make menuconfig
Compile all and build rootfs image:
$ make
Prepare your SDCard
===================
Buildroot generates a ready-to-use SD card image that you can flash directly to
the card. The image will be in output/images/sdcard.img.
You can write this image directly to an SD card device (i.e. /dev/xxx):
$ sudo dd if=output/images/sdcard.img of=/dev/xxx
$ sudo sync
Finally, you can insert the SD card to the Tinker RK3288 board and boot it.

This document explains how to set up a basic Buildroot system on
various Atmel/Microchip boards. Additional details can also be found
on the Linux4SAM website: http://www.linux4sam.org
This guide covers the following configurations:
- at91sam9g45m10ek_defconfig
- at91sam9rlek_defconfig
- at91sam9x5ek_defconfig (at91sam9g15, at91sam9g25, at91sam9x25,
at91sam9g35 and at91sam9x35)
- atmel_sama5d3xek_defconfig (sama5d31, sama5d33, sama5d34, sama5d35,
sama5d36)
- atmel_sama5d3_xplained_defconfig
- atmel_sama5d3_xplained_dev_defconfig
- atmel_sama5d3_xplained_mmc_defconfig
- atmel_sama5d3_xplained_mmc_dev_defconfig
- atmel_sama5d4_xplained_defconfig
- atmel_sama5d4_xplained_dev_defconfig
- atmel_sama5d4_xplained_mmc_defconfig
- atmel_sama5d4_xplained_mmc_dev_defconfig
- atmel_sama5d2_xplained_mmc_defconfig
- atmel_sama5d2_xplained_mmc_dev_defconfig
- microchip_sama5d27_wlsom1_ek_mmc_defconfig
- microchip_sama5d27_wlsom1_ek_mmc_dev_defconfig
- microchip_sam9x60ek_mmc_defconfig
- microchip_sam9x60ek_mmc_dev_defconfig
These configurations will use AT91Bootstrap, u-boot and a linux kernel from
the git trees maintained by Atmel.
The configurations labeled as 'dev' provide a development rootfs with tools to
tests the features of the SoC:
- ALSA tools to test audio
- FFMPEG to record video from the ISI/ISC
- I2C, SPI, CAN, etc. tools
- modetest for LCD screens, HDMI
- Wilc1000/Wilc3000 firmware for the Atmel Wireless sdio module
- SSH for convenience
- GDB/GDB server for debug
Configuring and building Buildroot
==================================
For the Xplained/Evaluation Kit boards, the Buildroot configuration is
provided to boot from an SD card. Those configurations are labeled as
'mmc'. In this case, after building Buildroot, follow the instructions
in the "Preparing the SD card" section.
For the other configurations listed above, the Buildroot configuration
assumes the system will be flashed on NAND. In this case, after
building Buildroot, follow the instructions in the "Flashing the NAND
using SAM-BA" section below.
To configure and build Buildroot, run:
make <board>_defconfig
make
Flashing the NAND using SAM-BA
==============================
Flashing the board
------------------
Connect the board:
o at91sam9g45m10ek: DBGU: J10, USB sam-ba: J14
o at91sam9rlek: DBGU: J19, USB sam-ba: J21
o at91sam9x5ek: DBGU: J11, USB sam-ba: J20
o sama5d3xek: DBGU: J14, USB sam-ba: J20
o sama5d3 Xplained: DBGU: J23, USB sam-ba: J6
o sama5d4ek: DBGU: J22 or J24, USB sam-ba: J1
o sama5d4 Xplained: DBGU: J1, USB sam-ba: J11
Start the board in RomBOOT:
o at91sam9g45m10ek:
1. open JP8, JP10 and JP12
2. start the board
3. close JP8, JP10 and JP12
o at91sam9rlek:
1. J11 on 1-2 (BMS=1), open J12 and J13
2. start the board
3. close J12 and J13
o at91sam9x5ek:
1. open JP9 and:
- Cogent: open *NCS jumper
- Embest: open SW1
- Ronetix: open J1 and J2
2. start the board
3. close JP9 and:
- Cogent: close *NCS jumper
- Embest: close SW1 (ON position)
- Ronetix: close J1 and J2
o sama5d3xek:
1. start the board
2. push BP4 and BP1
3. release BP1
4. release BP4
o sama5d3 Xplained:
1. open JP5 (NANDCS) and JP6 (SPICS)
2. start the board
3. close JP5 ans JP6
o sama5d4ek:
1. start the board
2. push BP3 and BP4
3. release BP4
4. release BP3
o sama5d4 Xplained:
1. close JP7 (BOOT_DIS)
2. start the board
3. open JP7
"RomBOOT" should appear on your console (this should be ttyUSBx or ttyACMx)
Now locate the USB sam-ba interface it should be ttyACMx, usually ttyACM0
dmesg on your machine should give:
usb 1-2.1.4: New USB device found, idVendor=03eb, idProduct=6124
usb 1-2.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
cdc_acm 1-2.1.4:1.0: ttyACM0: USB ACM device
Look for idVendor=03eb, idProduct=6124, this is the interface you want to use.
You can then flash the board using the provided flasher.sh script in board/atmel:
board/atmel/flasher.sh <builddir_path> <interface> <board>
For example, for an out of tree build made in
/tmp/atmel_sama5d3_xplained/ for the sama5d3 Xplained, you would use:
board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained
Reboot, the system should boot up to the buildroot login invite.
Preparing the SD card
=====================
An image named sdcard.img is automatically generated. With this image,
you no longer have to care about the creation of the partition and
copying files to the SD card.
You need at least a 1GB SD card. All the data on the SD card will be
lost. To copy the image on the SD card:
/!\ Caution be sure to do it on the right mmcblk device /!\
dd if=output/images/sdcard.img of=/dev/mmcblk0
Insert your SD card in your Xplained/Evaluation Kit board, and
enjoy. The default U-Boot environment will load properly the kernel
and Device Tree blob from the first partition of the SD card, so
everything works automatically.
By default a 16MB FAT partition is created. It contains at91bootstrap,
u-boot, the kernel image and all dtb variants for your board. The dtb
used is the basic one:
U-Boot> print
[...]
bootcmd=fatload mmc 1:1 0x21000000 at91-sama5d2_xplained.dtb; fatload mmc 1:1 0x22000000 zImage; bootz 0x22000000 - 0x21000000
[...]
If you want to use a variant such as the _pda7 one, you will have to
update your u-boot environment:
U-Boot> setenv bootcmd 'fatload mmc 1:1 0x21000000 at91-sama5d2_xplained_pda7.dtb; fatload mmc 1:1 0x22000000 zImage; bootz 0x22000000 - 0x21000000'
U-Boot> save
Saving Environment to FAT...
writing uboot.env
done
