This is a weird problem. I have a MPMC2 based PPC system with Flash memory
attached via opb_emc. The design works fine including the flash memory,
which is used for loading FPGA itself amongst other things. However I can't
read its content from gdb. All I see is zeros... I am using EDK8.2 for this
project and I believe I used to be able to read the flash just fine. It is
possible though that when I did it last time I had EDK8.1... Does anyone
have an idea of what I can be doing wrong here?
