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 Files
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.
