Hi Gilad,
A little while ago I wrote my own GPIO driver for the Au1000, mainly as a learning experience. I never bothered to release it because a driver already exists and I thought it was working. I'm not sure if it will work on the Au1550, but if you're interested you can find the source code here:

Cheers, Charles

Thanks. Can't I just mmap /dev/mem and use the GPIO offset from SYS_BASE?

Hello,
I am trying to use the au1000_gpio driver, but I'm a
little clueless as to how it is meant to be used. Can I use the GPIO ioctl's from a userland program, or must I write a kernel module?
I'll see if I can dig up some docs and the example userland program this weekend. That driver hasn't been tested in a while though.
