Hi, I have got the u-boot up and running on my Xilinx ML507 development board, but for some reason, it is missing the fatload command. If someone could tell me which config option controls the inclusion of the fatload command into the u-boot image, it would be great.
Without the fatload command, I am unable to load the linux kernel images from my compact flash drive.
The Xilinx git repo is located at git://git.xilinx.com/u-boot-xlnx.git, and I'm using the microblaze branch. The master branch doesn't work, and is very old.
Here is the output of the u-boot help command:
