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

NOTE: The above currently generates a compiler error using the toolchain that comes with Ubuntu's gcc-arm-linux-gnueabi package as follows:

... snip ...
arm-linux-gnueabi-gcc  -g  -Os   -fno-common -ffixed-r8 -msoft-float  -D__KERNEL__

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.
