This was way faster than understanding all the involved APIs and creating glue code between them. And the amount of time it needs was easy to estimate. However accidently I ran over the "old school" userland mmap code with /dev/mem. I already knew mapping with /dev/mem is possible but I haven't thought this could make a difference. http://ozlabs.org/pipermail/linuxppc-embedded/2006-August/023811.html Also I was wrong with my assumption that uio worked well on the peripherals. It worked (very) well on the leds, just to fool me!!! But it returned crap on some version registers. With a working and a non working version of mmap it should be rather easy to trace this bug. Unfortunately I was already short of time before running into this (and other) problems and it didn't get any better. So I would need some help from someone with more experience to fix this. Any instructions?
