Hi Stan!
I just got finished installing the new buck board. I used 7V and 250mA to power the device this time. With USB-C cable plugged in I plugged in the barrel connector and immediately saw that the QMX showed up on my PC and the power supply indicated about 200mA were being pulled. This is still concerning since the instructions specifically state there should be zero power draw until the left rotary encoder is pushed in.
I tried unplugging and replugging a few times, also attempted a firmware flash, but the behavior of immediately powering on still persists. After attempting the firmware flash, the device still powers on immediately upon being connected to power, but I now see black squares across the screen where as before the flash I saw no characters at all. I'm still puzzled as to where things are going wrong. I assume the issue that blew out the components mentioned in my earlier post is still lingering somewhere. The reduced power supplied is probably preventing anything from blowing but I'm at a loss as to what's going wrong. Any guidance would be greatly appreciated!
