Thanks!
Tried to do some memory display commands but got instant segmentation fault, and tried to run it as root - but then some bad things happened, so now I know no one should run it as root.
Good lesson to learn :-)
There was a revert of the memory map code in cmd_mem.c about a month ago - if you track that down and un-revert it then md will work for you.
The real fix is to devise some third meaning of a memory address (physical address, effective address, ...?) - I did post a suggestion to the list but no response and I haven't got back to it.

I wanted to tryout a memory test algorithm I developed, but it seem u-boot runs with no ram access. If I could findout the ram address where it is located, I think then the 8MB it says it has wouldn't give me segmentation fault...

Hello,
Does anyone know if exists somekind of simulator to run u-boot in test mode?
Have a look at the sandbox 'board' - It allows U-Boot to be run as an executable in Linux to test non hardware specific code
do:
make sandbox_config make all

Graeme
