Hi,

I'm trying to configure the interrupt controller using Altera tutorial :ftp://ftp.altera.com/up/pub/altera_material/14.0/tutorials/using_gic.pdf

However, when I run the code example provided in the tutorial I'm getting Segmentation Fault in command: *(int *)address |= value;

and the address is: address = 0xFFFED100 + reg_offset;

I understood that the base address of the interrupt controller is 0xFFFED100.

Do you know what may be the problem?

Thanks,
