Using memory other than EPCS/EPCQ

Hi,

Some years ago I was trying some similar operation using some equivalent serial flash than EPCQ. At that point, I observed similar issue of NIOS getting hanged or operation failure. I remember that, when NIOS performs the operation (write/read/erase), it initially checks for the Silicon ID in the Serial flash. This silicon ID differs between EPCQ/EPCS to that of other serial flashes. As the Silicon ID differs for other serial flash device, the NIOS halts/hangs with that operation.

With Regards,
