It's about time you provide us with more informatino on the problem in
order for us to help you.  I.e. what kernel version do you work with,
how does your driver implement the mmap call, how do you "try to write"
from userspace, what is the actual error, i.e. provide logs from the
kernel, etc.

As long as we don't have this info, we can only speculate.

Cheers
