Hi,
I am trying to directly access shared ram at address 0x80000000 either from a kernel module or user space and I don't want to use syslink.
My understanding is that I have to open /dev/mem and use mmap to map memory but my attempts were unsuccessful .
Cat /proc/iomem does not show any region for shared ram.
I also noticed this message at boot:
BUG: mapping for 0x80000000 at 0xfffe0000 out of vmalloc space
Any help is greatly appreciated.
