Hi,
I'm trying to do reads/writes to a flash device on our board using the Microblaze processor. The part itself is the same as featured on the Insight board for the XC2V1000 eval board.
When I simply try and read back the manufacturer and id codes, I get the value 0x00AA00AA instead - incorrect value. Any erase or write operations also fail.
I'm using EDK 6.3 and an opb_emc peripheral - I used to use an opb_memcon (I think) on previous versions of the EDK and this worked ok with the same board.
It's a combined SRAM/Flash device and the SRAM works ok. I've no clue why it now fails.
Cheers,
Pete.
