Well, it depends on your platform as system ram starts in different locations on different platforms. For example: U-Boot# bdi arch_number = 0x00000E05 boot_params = 0x80000100 DRAM bank = 0x00000000 -> start = 0x80000000 -> size = 0x40000000 ... And you also need to keep in mind where you load your kernel into memory and how big it is. -- Tom
