Did you properly set multiplexed pin functions? I did not play with 8.3

+0200. It contains some 9.0-CURRENT of that time patches, most probably
MPP settings need to be changed a bit in your case too.

I hope you can find how to set MPP functions and mge1 will work for you.

find something in older post mentioned in it.
