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
