Using devmem2 to access GPIO and HW registers on AT91SAM9260

["Paul Kavan" <pkavan@xxxxxxxxx>]

Hello all:

Some kind folks from this list have helped me determined that mmap
ought to be able to access the pins and registers on an at91sam9260. I
have some code compiled to do just that. The only difficulty now is
determining where linux is mapping these to. Has anyone had any
success using devmem2 with at at91sam9260 or something similar to
read/write pins/registers. If so, how did you determine where to
locate those items on the mmap?

Thanks.


Paul
