We have made good progress in getting the 02.01.03.11 Linux to boot on our custom board (CUS part). It seems
we are having trouble programming the GPTIMER1 (see output below). Can anyone help me
figure out what might be wrong? We have looked at the kernel code but have been unable to
find anything. Also looked at the .config to see if we could have anything misconfigured.
Thanks.
