Hi RY,

Now, I have been able to set GPMC_CONFIG7->MASKADDRESS = 0(256MByte) without data abort.
But, the GPMC_A[11] have not been driven.
Other address pins GPMC_A[10:1] can operate completely.

Have you solved your problem that you are not able drive the A11 signal ?
If you got fixed, could you please update us, so that it could help others.
