Hi Jason,
Yes, I was using Derek Molloy's DTS file as a template. The only
difference is that I edited it for the following
0x198 0x37 /* P9_30 102 OUTPUT MODE7 */
I posted the relevant dmesg output in my first post. I wasn't sure how to
attach a file to this thread...
Guy:
I did look at both DTS files and as far as I could tell there is not a
conflict with pins. I also tried assigning other GPIO pins values, and
those did not take effect either.
