I have a few overlays that conflict with the universal cape, but I want a subset of that functionality so I can enable pruout on pins P8.39-46. I pulled out the code sections of the universal cape that deal with these pins to create a custom cape, and this works quite well on the BBB and BBGW but disables WiFi on the BBBW. Not sure what the problem is, because these same pins get enabled just fine when I load the universal cape.
Thanks for any suggestions for avenues to try!

Here’s the code for the overlay (BB-EGPIO): https://pastebin.com/49NJgyBC
