Re: Testing hte CPU

Hi,
Since uClinux is working, can you inform us about the devices, memory map and
the size of the OS on flash or SRAM?
We have to remember that OR1K uses two external memories (Instruction and
Data) I think I have to dump the instructions only to the SRAM.

I found SRAM and Flash controllers with the OpenRisc1K test application on
the XSV board. Do you think we can use them?

Regards,
Jamil
