Hello,
This is probably one of those silly questions again, and I seem to be having
a lot of them lately.
I will like to access some memory mapped registers through user space
applications.
Do i just use the "mmap" function calls to map the physical memory to my
user space?
My BR/OR registers are set up properly to handle the addresses, but do i
need to configure
the kernel for those memory regions?
The address I am looking at is at physical location 0x60000000 and
0x40000000. My RAM space is mapped to
virtual address starting at 0xc0000000 (where the RAM's physical address is
from 0x0 - 0x00ffffff)
THank you very much for your help
Cecilia
