Hi again Andy, At least this time I read your question more thoroughly :) We are becoming off-topic for the U-Boot list -- if you want to take this further, switch to the linuxppc list. I can tell you for a start that you will need to customize your Linux .config file (make menuconfig for example) for your particular target, and you will also want to study the platform-specific code under arch/ppc/platforms. If your target is not currently supported, you will need to create that support. That means *at least* the files under arch/ppc/platforms, and the Makefile and Config.in changes needed in the tree to support selection of the new platform and its features. I encourage you to do a search of the entire Linux tree (not case sensitive) for a word like "walnut": find . -type f |xargs grep -i walnut This will give you a feel for the places that platform-specifics pop up. Hope that helps, Chuck
