Re: [beagleboard] Getting EQEP2 to work on the PocketBeagle

This has been very helpful but I have a problem - the position counter only decrements in my python code. The signals from my AMT103-V capacitive encoder from CUI, Inc, look good on my oscilloscope but unplugging P2_33 doesn't change a thing (position continues to decrement) while unplugging

Hi, I'm trying to hook up a PocketBeagle to a pololu Zumo chassis. After getting QEP0 to function I'm now struggling to get QEP2 going. Once I add the U-Boot overlay for it the PocketBeagle does not boot anymore. I'm guessing that I'm missing something in the device tree stuff for the
