Pinmux for BeagleBone Black, AM335x and OSD335x

A reference table for mapping BeagleBone Black header pins to OSD335x and AM335x pinmux options

Pinmux for BeagleBone Black, AM335x and OSD335x

I keep finding that I need to translate GPIO pin names and numbers depending on whether I am talking to a hardware designer, writing device trees, or looking up a solution based on the BeagleBone Black.

That normally means checking data across several different documents, so I pulled the common references into one place.

This reference is wide by nature, so you may need to scroll horizontally depending on your screen size. You can also search across the whole table or narrow it to P8 or P9.
