More information than you can shake an ESP32 at:

Rather than use a lot of Serial.print statements in your code, just connect up a cheap JTAG module from Espressif (the designers of the ESP32) to be able to step through your code a line at a time.

Boards I've found to work reliably
► ESP32 Mini T7 v1.3
► TTGO ESP32 V1.8 / V1.7.1
► Espressif ESP32 DevKit 1
Basically, all the boards I own with a lidded "module" on them do not work. You get an error about being unable to get the memory maps.🤷
This is unfortunate (for me) as I have many WROOM and WROVER modules!
