doing md 0805283e works
if I can change the base address now, every memory command should work

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.
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
