I'm starting to question if this is really true (or that it is all working
correctly). As far as I can see, what you're doing is correct.
Try this:
RedBoot> fi loa RedBoot -b 0xa1800000
RedBoot> d -b 0xa1800000 -l 0x80
You should see the first part of the RedBoot image which is stored in Flash,
but has been loaded into high memory.
Alternatively, you could run a RAM test (we have some in eCos) that will verify
that the memory is actually working.
