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 firmware for the Atmel Wireless sdio module
- SSH for convenience
- GDB/GDB server for debug
Configuring and building Buildroot
----------------------------------
==================================
For most 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.
For the Xplained boards, an alternative 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 "Preparting the SD card" sction.
To configure and build Buildroot, run:
make <board>_defconfig
make

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 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
A 512MB ext4 partition is also created to store the rootfs generated.
If you want to customize the size of the partitions and their content,
take a look at the the genimage.cfg file in the board directory.

Atmel SAMA5D3 Xplained board
============================
This document explains how to set up a basic Buildroot system on the
Atmel SAMA5D3 Xplained board, whose main site is
http://www.atmel.com/tools/ATSAMA5D3-XPLD.aspx. Additional details can
also be found on the http://www.at91.com/linux4sam/bin/view/Linux4SAM/
web site.
Note that the default Buildroot configuration is prepared to boot from
an SD card: the first stage bootloader, second stage bootloader,
kernel image and root filesystem are all located on the SD card. Some
adjustments in the bootloader configuration will be needed to boot
from NAND flash, see board/atmel/readme.txt
Configuring and building Buildroot
----------------------------------
make atmel_sama5d3_xplained_mmc_defconfig
make
Preparing the SD card
---------------------
The SD card must be partitioned with at least two partitions: one
FAT16 partition for the bootloaders, kernel image and Device Tree
blob, and one ext4 partition for the root filesystem. To partition the
SD card:
sudo sfdisk -uM /dev/mmcblk0 <<EOF
,64,6
;
EOF
This creates a 64 MB partition for the FAT16 filesystem (type 6) and
uses the rest for the ext4 filesystem used for the root filesystem.
Then, format both partitions:
sudo mkfs.msdos -n boot /dev/mmcblk0p1
sudo mkfs.ext4 -L rootfs -O ^huge_file /dev/mmcblk0p2
Note: the -O ^huge_file option is needed to avoid enabling the huge
files features of ext4 (to support files larges than 2 TB), which
needs the kernel option CONFIG_LBDAF to be enabled.
Mount both partitions (if not done automatically by your system):
sudo mount /dev/mmcblk0p1 /media/boot
sudo mount /dev/mmcblk0p2 /media/rootfs
Copy the bootloaders, kernel image and Device Tree blob to the first
partition:
cp output/images/u-boot-spl.bin /media/boot/boot.bin
cp output/images/u-boot.img /media/boot/u-boot.img
cp output/images/zImage /media/boot/zImage
cp output/images/at91-sama5d3_xplained.dtb /media/boot/at91-sama5d3_xplained.dtb
Extract the root filesystem to the second partition:
sudo tar -C /media/rootfs -xf output/images/rootfs.tar
Unmount both partitions:
sudo umount /media/boot
sudo umount /media/rootfs
Insert your SD card in your Xplained board, and enjoy. The default
U-Boot environment will properly load the kernel and Device Tree blob
from the first partition of the SD card, so everything works
automatically.
