The format of the "eeprom" command is (as I'm sure you already know):
eeprom {read,write} <addr> <offset> <count>
The <addr> argument is the MEMORY address and that's where the result of
the transaction will be placed.
Thus,
1) Using 0 as <addr> is a pretty risky idea to begin with: :)
2) The more proper usage will be:
eeprom read 0x100000 0 10
md.b 0x100000 10
And, of course, a quick look at the source code is worth thousand emails :)
Happy hacking,
Vladimir
