Honored ContributorI look into this further but:
1 - You don't need a chipselect. 2 - You don't need byteenables. If you don't include them in the interface, then all bytes are valid when a write occurs. 3 - In your TCL script, it looks like you have the readWaitTime set to 1 which should take care of the 1 clock latency on your read. Nevertheless, there is no reason to wait for a read to change the readdata in this case. When you read the data, are you getting the same value every time (indicating that your P_line and P_col registers are never changed)? Jake
