PandaBoard ES uboot howto
Getting the Source
to get the source code for u-boot, clone a copy of the linaro u-boot stable tree:
mkdir pandaboard-es cd pandaboard-es git clone git://git.linaro.org/boot/u-boot-linaro-stable.git cd u-boot-linaro-stable git checkout -b pandaboard-es origin/Linaro-u-boot-2011.12
As of 12/18/2011 the master branch tagged Linaro-u-boot-2011.12 produces a working MLO/u-boot pair which will boot both Panda and Panda-ES boards. Previously, the Panda EA1 with rev ES2.0 silicon would not boot.
Configure and Compile
to configure and compile u-boot for PandaBoard ES do the following:
make omap4_panda_config make
copy the MLO and u-boot images to the boot partition of your mounted sd card
cp MLO /media/boot cp u-boot.img /media/boot sync
make sure you unmount your sd card prior to removing it from the host pc.
