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: http://members.rogers.com/charles.eidsness/au1000_gpio.c http://members.rogers.com/charles.eidsness/au1000_gpio.h Cheers, Charles Gilad Rom wrote: > Thanks.
