Pinmux for Beaglebone Black, AM335x and OSD335x

Iain Menzies-Runciman

I keep finding that I need to translate GPIO pin names and numbers depending on if I am talking to our hardware designer, writing DTBs or looking up solutions based on the BeagleBone Black.

This normally involves looking up data in 3 different pages – so I thought I would combine them all into one place.

The resulting table is too large to fit on the page, so you may need to scroll horizontally to see all the columns.
