Barebox
You can use barebox on with the following support
- uart
- nand
- ethernet
- usb host
- sd card (mci)
- spi
- generic barebox features (menu, hush, multi-devices, etc...)
1) First you need to clone the tree
The board support is currently in the next branch
git clone git://git.pengutronix.de/git/barebox.git git checkout -b work origin/next
2) Then you need to configure it
For the 64 MiB board
make usb_a9g20_defconfig
For the 128 MiB board
make usb_a9g20_128mib_defconfig
3) Compile it
make
4) Flash it
now you need to flash it via
- SAM-BA
- OpenOCD
5) start the board

Linux
You can use the mainline kernel (merge in release 3.1)
1) First you need to clone the tree
git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git git checkout -b work
2) Then you need to configure it
currently no defconfig is merge for the next release you could use at91sam9g20_defconfig but right now you need to use at91sam9g20ek_defconfig and select it via Kconfig "CALAO USB-A9G20"
make at91sam9g20ek_defconfig make menuconfig
or
make at91sam9g20ek_defconfig sed -i -e "s:# CONFIG_MACH_USB_A9G20 is not set:CONFIG_MACH_USB_A9G20=y:g" .config
3) Compile it
make uImage
4) Run it
You can run it via nfs or tftp from barebox
for this you need to modify the /env/config
a) on board
via
ed /env/config
b) on pc
by editing
diff --git a/arch/arm/boards/usb-a926x/env/config b/arch/arm/boards/usb-a926x/env/config
