SYS GPIO API problem after rebuild

Thu Feb 23, 2006 2:37 am

Hi,
I have a problem with an existing driver. I used to access GPIOs through the System API interface. We have moved the uboot on the parallel flash of AT92RM9200EK, and are not using the dataflash.

Now the previously operating driver cannot write proper GPIO API requests. WHat do we need to have in order to use the AT91RM9200 SYS API for the GPIOs? What is necessary for the driver to have an access to such? What could block it?
