0xc0000000 are virtual kernel addresses; not physical addresses.  If
the MMU is still on, then you need to use the virtual address to
examine memory.  If the MMU is off (such as after reloading u-boot),
then you need to change 0xCxxxxxxx to 0x0xxxxxxxx.

I don't know; I've never used XMD.  Read the XMD documentation.  You
can do it from u-boot too.
