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
