Hi, I am running two BBBs via power adapter, and I wanted to test the GPIO pins. One of them runs still on the manufacturing OS, the other one is up-to-date. Now I wanted to see the GPIO pin values with an oscilloscope. While trying to switch the pins on and off on the up-to-date-board via echo on/off > <pin> I experienced that the pin I wanted to switch never changed state. Therefore I tried to do the same on the other board, thinking that it was a software fault. But there I only measured a 50Hz-triangular signal, regardless which pin I chose (Even on GND and 5V). Why? What can I do to bring both of them back to work? Thanks!
