I tried to access the registers of IO ports based on the address provided in Ref. Manual, but It is giving segmentation fault. I given as follows..
unsigned char* x = (unsigned char*) 0xE0001440
(here 1440 is the offset address of the port-a's Open Drain Register)
after this I used mmap() to access the location in virtually.
Can you please help me in making GPIO pins to use.
Thanks and Regards,
