Hello,
has anybody tested the "mtest" command in uboot? I just entered the command and I get some errors. If I recompile uboot with a lower dram clock (e.g. 120MHz or 240MHz) the mtest command doesn't report the errors.
I have assembled my own board with the DDR3 RAM and A13 processor. So, I'm not sure if this is a problem of my board or it is an uboot issue. Maybe someone can test the command on a board from Olimex.
Thanks,
Andreas
I used it and found its defaults for the memory addresses were wrong, so it tested non-existent and ROM memories! Yes, you get errors like you did.
Worked OK when I put in all the values properly.
As I recall, the help was wrong as to how you specify the values. I ended up reading the source code.
