Dear All,

My frame work of device driver works well, but:

My trouble in processing GPIO in my device driver are as follows:

1) can not use this kind of sentence in my isr routine:
*(volatile unsigned long *)0x10000080 = 0xf0000000;

2) also can not initialize the GPIO while initializing my device.

Please help me.
