Programming Issue - Adafruit ESP32-S2

Other Hardware 3rd Party Boards
1

I'm not sure whats going on, I have three boards, and all of them are doing the same thing. For now I'm just doing test codes, to resolve this. Codes upload just fine, when I hit reset, the Serial Monitor shows this. Also, the only light that comes on now is the red power light, nothing else.

My hunch is one or more of the settings in the Tools menu is wrong. Check the esp32-S2 docs for guidance. OR try Partition settings then Flash Mode

I figured it out..took a while. Adafruit lists the unit as a ESP32-S2 Dev Feather board. I was selecting the board as Adafruit Feather ESP32-S2. What I needed to choose was just ESP32-S2 Dev Board. Kind of generic. Usually Adafruit is good with their documentation, but they missed this one.
