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

Acme Systems Acqua A5
Intro
=====
The Acqua A5 is a system on module based on the Microchip SAMA5D31 SoC:
https://www.acmesystems.it/acqua
The files here support configurations that build a microSD image for a
minimal system that can be accessed through the serial console. You will
need an USB-to-serial interface in order to access that console from
your computer:
https://www.acmesystems.it/DPI
How to build the image
======================
If you have an Acqua module with 256 MiB of RAM, type:
$ make acmesystems_acqua_a5_256mb_defconfig
If you have the 512 MiB version, type instead:
$ make acmesystems_acqua_a5_512mb_defconfig
You can optionally tweak the configuration and add packages by typing:
$ make menuconfig
Then, proceed with the build:
$ make
How to write the microSD card
=============================
The system image is the file "sdcard.img" in the "output/images"
directory. Write it to the card by invoking:
$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
where `sdX' is the block device representing the microSD card.

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.

Intro
=====
This default configuration will allow you to start experimenting with the
Buildroot environment for the Bananapi M2 Zero. With the current configuration
it will bring-up the board, and allow access through the serial console.
Bananapi M2 Zero link:
http://www.banana-pi.org/m2z.html
This configuration uses U-Boot mainline and kernel mainline.
How to build
============
$ make bananapi_m2_zero_defconfig
$ make
Note: you will need access to the internet to download the required
sources.
How to write the SD 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
$ sync
Insert the micro SDcard in your Bananapi M2 Zero and power it up. The console
is on the Debug UART on the CON3 header, with serial settings 115200 8N1.

BeagleV
=======
BeagleV is a low-cost RISC-V 64-bit based platform, powered by a
Starfive JH7100 processor. The current defconfig in Buildroot has been
tested with the JH7100 chip used on the beta version of the BeagleV
board.
How to build
============
$ make beaglev_defconfig
$ make
Build results
=============
After building, output/images contains:
+ bootloader-BEAGLEV-buildroot.bin.out
+ ddrinit-2133-buildroot.bin.out
+ Image
+ fw_payload.bin
+ fw_payload.bin.out
+ fw_payload.elf
+ rootfs.ext2
+ rootfs.ext4
+ sdcard.img
+ u-boot.bin
The four important files are:
- bootloader-BEAGLEV-buildroot.bin.out, the first stage bootloader
- ddrinit-2133-buildroot.bin.out, the DDR initialization firmware
- fw_payload.bin.out, which is the bootloader image, containing
both OpenSBI and U-Boot.
- sdcard.img, the SD card image, which contains the root filesystem,
kernel image and Device Tree.
Flashing the SD card image
==========================
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Preparing the board
===================
Connect the Beagle-V fan to the 5V supply (pin 2 or 4 of the GPIO
connector) and GND (pin 6 of the GPIO connector).
Connect a TTL UART cable to pin 8 (TX), 10 (RX) and 14 (GND).
Insert your SD card.
Power-up the board using an USB-C cable.
Flashing OpenSBI/U-Boot
=======================
The bootloader pre-flashed on the Beagle-V has a non-working
fdt_addr_r environment variable value, so it won't work
as-is. Reflashing the bootloader with the bootloader image produced by
Buildroot is necessary.
When the board starts up, a pre-loader shows a count down of 2
seconds, interrupt by pressing any key. You should reach a menu like
this:
--------8<----------
bootloader version:210209-4547a8d
ddr 0x00000000, 1M test
ddr 0x00100000, 2M test
DDR clk 2133M,Version: 210302-5aea32f
0
***************************************************
*************** FLASH PROGRAMMING *****************
***************************************************
0:update uboot
1:quit
select the function:
--------8<----------
Press 0 and Enter. You will now see "C" characters being
displayed. Ask your serial port communication program to send
fw_payload.bin.out using the Xmodem protocol.
After reflashing is complete, restart the board, it will automatically
start the system from the SD card, and reach the login prompt.
Flashing low-level bootloaders
==============================
The BeagleV comes pre-flashed with functional low-level bootloaders
(called "secondboot" and "ddrinit"). Re-flashing them is not necessary
to use this Buildroot defconfig. However, for the sake of
completeness, Buildroot builds and provides those low-level bootloader
images.
You can flash them as follows:
- In the same "pre-loader" menu as the one used above, instead of
entering 0 or 1, enter the magic "root@s5t" string. This enters the
"expert" features.
- Then, press 0 and send over X-modem the
bootloader-BEAGLEV-buildroot.bin.out file.
- Then, press 1 and send over X-modem the
ddrinit-2133-buildroot.bin.out.
Note that the reflashing mechanism itself relies on those low-level
bootloaders, so if you flash non-working versions, you'll have to go
through a recovery process. This requires wiring up to a separate
debug UART, which pins are located near the HDMI connector. See
https://wiki.seeedstudio.com/BeagleV-Update-bootloader-ddr-init-boot-uboot-Recover-bootloader/
section "Recover the bootloader" for more details. The instructions
make use of a jh7100-recover tool, which Buildroot has built as part
of this defconfig: it is available as output/host/bin/jh7100-recover.

Mediatek MT8173 aka Chromebook Elm
==================================
This file describes booting the Chromebook from an SD card containing
Buildroot kernel and rootfs, using the original bootloader. This is
the least invasive way to get Buildroot onto the devices and a good
starting point.
The bootloader will only boot a kernel from a GPT partition marked
bootable with cgpt tool from vboot-utils package.
The kernel image must be signed using futility from the same package.
The signing part is done by sign.sh script in this directory.
It does not really matter where rootfs is as long as the kernel is able
to find it, but this particular configuration assumes the kernel is on
partition 1 and rootfs is on partition 2 of the SD card.
Make sure to check kernel.args if you change this.
Making the boot media
---------------------
Start by configuring and building the images.
make chromebook_elm_defconfig
make menuconfig # if necessary
make
The important files are:
uImage.kpart (kernel and device tree, signed)
rootfs.tar
bootsd.img (SD card image containing both kernel and rootfs)
Write the image directly to some SD card.
WARNING: make sure there is nothing important on that card,
and double-check the device name!
SD=/dev/mmcblk1 # may be /dev/sdX on some hosts
dd if=output/images/bootsd.img of=$SD
Switching to developer mode and booting from SD
-----------------------------------------------
Power Chromebook down, then power it up while holding Esc+F3.
BEWARE: switching to developer mode deletes all user data.
Create backups if you need them.
While in developer mode, Chromebook will boot into a white screen saying
"OS verification is off".
Press Ctrl-D at this screen to boot Chromium OS from eMMC.
Press Ctrl-U at this screen to boot from SD (or USB)
Press Power to power it off.
Do NOT press Space unless you mean it.
This will switch it back to normal mode.
The is no way to get rid of the white screen without re-flashing the bootloader.

From e9a88fddc149fc52cdc5a8997f9fd3a29416c643 Mon Sep 17 00:00:00 2001

Subject: [PATCH] mx6qsabre_common: boot Linux to /init in mfgtools mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Buildroot supplies a nice /init wrapper script to use when booting from a
ramdisk.
This patch tells u-boot to tell the kernel to boot into /init (instead of
/linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a
buildroot system entirely through USB.

***************************
Freescale i.MX8MN EVK board
***************************
This file documents the Buildroot support for the i.MX8M Nano EVK board.
Build
=====
First, configure Buildroot for the i.MX8MN EVK board:
make freescale_imx8mnevk_defconfig
Build all components:
make
You will find in output/images/ the following files:
- bl31.bin
- boot.vfat
- ddr4_201810_fw.bin
- ddr_fw.bin
- fsl-imx8mn-ddr4-evk.dtb
- Image
- imx8-boot-sd.bin
- rootfs.ext2
- rootfs.ext4
- rootfs.tar
- sdcard.img
- u-boot.bin
- u-boot.imx
- u-boot.itb
- u-boot-nodtb.bin
- u-boot-spl.bin
- u-boot-spl-ddr.bin
Create a bootable SD card
=========================
To determine the device associated to the SD card have a look in the
/proc/partitions file:
cat /proc/partitions
Buildroot prepares a bootable "sdcard.img" image in the output/images/
directory, ready to be dumped on a SD card. Launch the following
command as root:
dd if=output/images/sdcard.img of=/dev/<your-sd-device>
*** WARNING! This will destroy all the card content. Use with care! ***
For details about the medium image layout, see the definition in
board/freescale/common/imx/genimage.cfg.template_imx8.
Boot the i.MX8MN EVK board
==========================
To boot your newly created system (refer to the i.MX8MNano EVK Quick Start Guide
[1] for guidance):
- insert the SD card in the SD slot of the board;
- Configure the switches as follows (X = "don't care"):
SW1101: 1100XXXXXX [D1-D10]
SW1102: XXXXXXXXXX [D1-D10]
- put a micro USB cable into the Debug USB Port and connect using a terminal
emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!

NanoPi R1
Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the NanoPi R1. With the current configuration
it will bring-up the board, and allow access through the serial console.
How to build it
===============
Configure Buildroot:
$ make friendlyarm_nanopi_r1_defconfig
Compile everything and build the SD card image:
$ make
How to write the SD 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

Fig 1: Overview of board
Notice difference in Ethernet port layout compared to the Globalscale
docs. They order the ports; LAN2, LAN1, WAN (left to right in figure
above). For more information, see http://espressobin.net
Building
--------
$ make globalscale_espressobin_defconfig
$ make
This generates the kernel image, the devicetree binary, the rootfs as a
tar.gz, and a filesystem image containing everything.
All build artifacts are located in `output/images/`
Booting
-------
To boot, you need a UART connection, using the on-board micro USB port
set to 115200 8N1.
By default, the ESPRESSObin comes with a pre-flashed U-Boot set up to
load the kernel, device-tree and rootfs from SPI NOR flash. The board
jumpers can be changed to boot from different sources, see the quick
start guide for each board revision for details:
- ftp://downloads.globalscaletechnologies.com/Downloads/Espressobin/ESPRESSObin%20V5/
- ftp://downloads.globalscaletechnologies.com/Downloads/Espressobin/ESPRESSObin%20V7/
Note: the v5, and earlier, cannot boot from sdcard, so you have to set
up the factory U-Boot to boot into Buildroot:
1. Flash rootfs image to sdcard drive, your `of=` device may differ:
$ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0 bs=1M
$ sync
2. Boot board from SPI NOR, interrupt boot by pressing any key ...
3. Check with `printenv` that the default setup is OK, otherwise ensure
the following are set, and define `bootcmd` for automatic boot:
> setenv kernel_addr 0x5000000
> setenv fdt_addr 0x1800000
> setenv fdt_name boot/armada-3720-espressobin.dtb
> setenv console console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000
> setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/mmcblk0p1 rw rootwait; booti $kernel_addr - $fdt_addr'
4. Call the boot command, or `reset` the board to start:
> run bootcmd
Networking
----------
To enable Ethernet networking, load the `mv88e6xxx` kernel module, and
bring up each respective interface needed:
# modprobe mv88e6xxx
# ifconfig wan up
A more advanced scenario is setting up switching between the ports using
the Linux bridge. The kernel switchdev layer, and DSA driver, ensure
switch functions are "offloaded" to the HW switch, i.e., all traffic
between LAN ports never reach the CPU. For this you need the iproute2
suite of tools.

Kontron pitx-imx8m
==================
https://www.kontron.com/produkte/pitx-imx8m/p155258
How to build it
===============
Configure buildroot:
$ make kontron_pitx_imx8m_defconfig
Change settings to fit your needs (optional):
$ make menuconfig
Compile everything and buildr the rootfs image:
$ make
Result of the build
===================
After building, the output/images directory contains:
output/images/
├── bl31.bin
├── boot.scr
├── ddr_fw.bin
├── Image
├── imx8-boot-sd.bin
├── imx8mq-kontron-pitx-imx8m.dtb

├── u-boot.bin
├── u-boot.itb
├── u-boot-nodtb.bin
├── u-boot-spl.bin
└── u-boot-spl-ddr.bin
Flashing the SD card image
==========================
To install the image on a SDCard simply copy sdcard.img to the storage (e.g. SD, eMMC)
$ sudo dd if=output/images/sdcard.img of=<your-sd-device>
Preparing the board
===================
* Connect a serial line to the board
* Insert the SD card
* Make sure the boot source selection DIP switches are set correctly
* SW1 1-4 OFF
* SW1 2-3 OFF
* Power-up the board
Booting the board
=================
By default the bootloader will search for the first valid image, starting
with the internal eMMC. To make sure the bootloader loads bootscript from
the correct location (SD card) set the boot_targets environment variable:
$ setenv boot_targets mmc1

Kontron SMARC-sAL28
===================
How to build it
===============
Configure Buildroot:
$ make kontron_smarc_sal28_defconfig
Change settings to fit your needs (optional):
$ make menuconfig
Compile everything and build the rootfs image:
$ make
Copying the image to a storage device
=====================================
Buildroot builds an image which can be written to the internal eMMC
storage, a SD card or an USB thumb drive. You can use the following
command on your host:
$ sudo dd if=output/images/sdcard-emmc.img of=/dev/sdx bs=1M
Where /dev/sdx is the corresponding block device of your SD card or USB
thumb drive. To flash it on your internal eMMC use the following command on
the board:
# dd if=sdcard-emmc.img of=/dev/mmcblk1 bs=1M
Be sure you have not booted from the internal eMMC in this case!
Booting the board
=================
By default the bootloader will search for the first valid image, starting
with the internal eMMC. Consult the vendor documentation on how to use the
DIP switches to select specific boot devices. To use the bootloader
environment set the boot_targets correspondingly. E.g.:
# setenv boot_targets usb0
To boot from an USB thumb drive.
The device tree is loaded according to the filename in fdtfile. The
following command will set the default device tree, which works on almost
all variants (with less features of course):
# setenv fdtfile freescale/fsl-ls1028a-kontron-sl28.dtb
Set this to a device tree which fits your board variant.
Connect your serial cable to SER1 and open your favorite terminal emulation
program (baudrate 115200, 8n1). E.g.:
$ picocom -b 115200 /dev/ttyUSB0
You will get a warning reported by fdisk when you examine the SD card.
This is because the genimage.cfg file doesn't specify the SD card size
(as people will naturally have different sized cards), so the
secondary GPT header is placed after the rootfs rather than at the end
of the disk where it is expected to be.
You will see something like this at boot time:
[ 4.552797] GPT:Primary header thinks Alt. header is not at the end of the disk.
[ 4.560237] GPT:266272 != 7864319
[ 4.563565] GPT:Alternate GPT header not at the end of the disk.
[ 4.569596] GPT:266272 != 7864319
[ 4.572925] GPT: Use GNU Parted to correct GPT errors.
Updating the bootloader
=======================
Buildroot will automatically build the u-boot bootloader. The resulting
image is called u-boot.rom and you can find it in the images/ directory.
To update the bootloader on the board you could either copy it to an
USB thumb drive or you could put it on a TFTP server. The following
example assumes you have the bootloader image copied to the root of
a thumb drive:
# usb start
# load usb 0:1 $loadaddr u-boot.rom
# sf probe 0 && sf update $fileaddr 0x210000 $filesize

OLPC XO Laptops
===============
This document explains how to build and run images that run on the OLPC
XO laptops.
Supported models
----------------
* OLPC XO-1
The original NS Geode based OLPC laptop, uses the x86 architecture.
Can be booted either from an internal MTD device formatted with JFFS2
or from a FAT or EXT4 partition on a SD card or a USB flash stick.
* OLPC XO-7.5
The ARM-based laptop. Needs a recent enough firmware to provide a good
enough flattened device tree to the kernel. Can be from a FAT or EXT4
partition on a internal eMMC, a SD card or a USB flash stick.
Configure and build
===================
$ make olpc_xo1_defconfig # Configure for XO-1
or:
$ make olpc_xo175_defconfig # Configure for XO-1.75
Then:
$ make menuconfig # Customize the build configuration
$ make # Build
Preparing the machine
=====================
Firmware security
-----------------
Most OLPC machines were shipped with the security system that disallows
booting unsigned software. If this is the case with your machine, in order
to run the image you've built on it you'll need to get a developer key and
deactivate the security system.
The procedure is descriped in the OLPC wiki:
http://wiki.laptop.org/go/Activation_and_Developer_Keys
Firmware upgrade
----------------
It is always preferrable to use an up to date firmware. The firmware images
are available at http://wiki.laptop.org/go/Firmware. For the XO-1.75 laptop
to boot the mainline kernel a firmware Q4E00JA or newer is needed. You can
get it at http://dev.laptop.org/~quozl/q4e00ja.rom.
To update the firmware, place the .rom file on to your bootable media,
connect a charged battery pack and a wall adapter, and enter the Open
Firmware prompt by pressing ESC during the early boot (needs an unlocked
laptop -- see "Firmware security" above). Then use the "flash" command
to update the firmware:
ok flash ext:\q4e00ja.rom \ Flash the "q4e00ja.rom" from the SD card
ok flash u:\q4e00ja.rom \ Flash the "q4e00ja.rom" from USB stick
Create the bootable SD card or USB flash stick
==============================================
When the build is finished, an image file called "sdcard.img" will be created.
It is suitable for writing directly to a SD card, USB flash stick or (on a
XO-1.75) the internal eMMC flash.
Before writing the image, please double check that you're using the right
device (e.g. with "lsblk" command). Doing the following will DESTROY ALL DATA
that's currently on the media.
# cat output/images/sdcard.img >/dev/<device>
Flashing the JFFS2 image (XO-1 only)
====================================
Unlike XO-1.75, the internal NAND flash on XO-1 is accessed without a
FTL and needs a flash-friendly filesystem. A build configured for XO-1
creates a file named "root.jffs2" that can be written to it.
One way to write it is from the Open Firmware prompt. First, partition
and format a USB flash disk with a FAT file system and place the
"root.jffs2" file onto it. Then power on the machine, enter the
Open Firmware port by pressing the ESC key and run the following:
ok patch noop ?open-crcs copy-nand \ Disable CRC check
ok copy-nand u:\root.jffs2
Booting the machine
===================
Once your machine is unlocked, it will automatically boot from your media
wherever it will detect it attached to the USB bus or the SD card slot,
otherwise it will proceed booting from the internal flash.

Where X is your SD card device.
Booting:
========
Orangepi-RK3399 by default boots from emmc. For SD card boot to
happen, emmc should be empty. If emmc happens to have any bootable
image then erase emmc so that bootrom will look for a proper image in SD.
emmc can be erased once after booted into linux as shown in below link.

Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the Orangepi Zero Plus. With the current configuration
it will bring-up the board, and allow access through the serial console.
Orangepi Zero Plus link:
http://www.orangepi.org/OrangePiZeroPlus/
This configuration uses U-Boot mainline and kernel mainline.
How to build
============
$ make orangepi_zero_plus_defconfig
$ make
Note: you will need access to the internet to download the required
sources.
How to write the SD 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
$ sudo sync
Insert the micro SDcard in your Orangepi Zero Plus and power it up. The console
is on the serial line, 115200 8N1.

Intro
=====
This is a board configuration for the apu2 platform by PC Engines.
https://pcengines.ch/apu2.htm
Since the apu2 does not have any graphical output, the default configuration
will ensure that the kernel output as well as the login prompt will be sent to
the serial port.
How to build
============
The provided defconfig creates a hybrid isolinux image that can be booted from
either an USB stick or a CD.
$ make pcengines_apu2_defconfig
$ make
How to write to an USB stick
============================
Once the build process is finished you will have an image
called "rootfs.iso9660" in the output/images/ directory.
Copy the bootable "rootfs.iso9660" onto the USB stick with "dd":
$ sudo dd if=output/images/rootfs.iso9660 of=/dev/sdX bs=1M conv=fsync
$ sudo sync
How to connect to the apu2
==========================
Connect to the DB9 serial port of the apu2 board (either directly or through a
USB adapter) with a baudrate of 115200.
For example with miniterm (part of pyserial):
$ miniterm.py -f direct /dev/ttyUSB0 115200

Intro
=====
The QEMU sbsa-ref machine is primarily meant for firmware development
and testing according to ARM's SBSA and SBBR standards.
Build
=====
$ make qemu_aarch64_sbsa_defconfig
$ make
Emulation
=========
Run the emulation with:
qemu-system-aarch64 \
-M sbsa-ref \
-cpu cortex-a57 \
-smp 4 \
-m 1024 \
-nographic \
-pflash output/images/SBSA_FLASH0.fd \
-pflash output/images/SBSA_FLASH1.fd \
-hda output/images/disk.img # qemu_aarch64_sbsa_defconfig
