kernel with access to ADC and GPIO for 9G20 board

After reviewing forum topics and trying to get info from foreign sources it has been impossible to get access to my 9G20 board peripherals using kernel 2.6.27.
I tried out upgrading to kernel 2.6.30 (the one that includes drivers for such peripherals) but acc. to glomation support that kernel is not supporting 9G20 board.

If experience on this is available please provide some guidance.
Thanks.

Re: kernel with access to ADC and GPIO for 9G20 board

The ADC and GPIO can be accessed in almost any version of kernels by means of direct access of the GPIO registers.  The 2.6.30 and up has GPIO driver built to support easy access from user space applications.  The GESBC-9G20 supports Linux 2.6.30 and up as long as you have correct patch set installed.  http://www.at91.com/linux4sam/bin/view/Linux4SAM/LinuxKernel has patches for different version of kernels.
