I'm doing "make LOADADDR=0x80008000 uImage" because > newer kernels won't build without the LOADADDR= bit. I build the kernel same way as you, and copy the zImage to boot partition. I am not using any boot.scr, a simple uEnv.txt to override the boot partition variables, and the default environment otherwise. My boot log is here, including my uEnv.txt at the end. http://hastebin.com/yinuxirexu.xml Hopefully, this should clear out any setup differences.. regards Suman
