Instruction OCM

[Koss, Mike (Mission Systems)]

How is your IOCM actually built into your system, i.e. what is its base
address? It cannot overlap with any other memory address in the system.

Dear all,

I cannot run Linux when I have an instruction OCM in my design but,
without instruction OCM everything is fine. I tried to do some
debugging. It seems that the Linux memory management unit has a problem
with that.  After entering the MMU initialization phase, it suddenly
jumps to address 0x00000700 it get stuck there. Is there anybody who
have tried a design with instruction OCM? Do I need to do special
configuration for the Linux kernel? 

Regards,

Mojtaba
