I have two of these DevKitM-1 v1.0 boards.
I think these are first gen ESP32 modules with the single cpu, so pretty old. Using IDE 1.8.19, I tried to program a simple blink app and serial app. After the flash is compete and it saids "leaving, hard resetting via RTS pin...", I see that the serial monitor is showing me the esp32 doing some core dump:
I've tried a couple of different esp32 boards thinking I selected the wrong hardware. I've tried "ESP32 Dev Module", which seems to be a dual core cpu. Same result with the core dump text from serial port.
