You are writing a 32 bit entity to an non 32-bit aligned address. Although I do not know the omap too well, this can be a problem on any architecture. Can you write 32-bot to that exact address from within the U-Boot commandline with e.g. "mm"? Cheers Detlev -- Q: What do you get when you cross an elephant and a banana?
