Sir,

Thanks for the reply. My settings are also same like you. Even though it is not working.

I am using Custom Board with 1MB Flash attached.

My setting in SOPC:

Address Width: 20-bit

Data Width: 8-bit

Timing:

Setup: 45

Wait: 160

Hold: 45

Unit: ns

Already added in Avalon MM Tristate Bridge.

For 1MB i am using 20-bit and you are using 22-bit for 8MB. Is their any mistake here?
