Another question: After my custom board finished initializations, It should load "linux kernel" into RAM. The question is : Is this a compressed "linux kernel" just like vmlinux.gz of X86 that I should load? Or is it "/usr/src/linux/vmlinux" that is not compressed that I should load? And what RAM address should it loaded at? Since it is linked at 0x80200000,Should I load there or at somewhere else? Thanks very much. machael
