ESP32 Debugging with ESP-Prog not working on Mac

[maxgerhardt]

Please read the other threads first on common errors.

• ESP32 WROOM-32 and JTAG timeout
• ESP32 & PIO Unified Debugger - #104 by bbeliveau

It pretty much always comes down to these issues:

• wrong target chip / board = .. selected in the platformio.ini
• incorrect wiring between adapter and target board
• target power supply unstable
• using a breadboard (bad signal integrity)
• JTAG speed too high / cables too bad or long
• wrong flash voltage (1.8V vs 3.3V) selected

Open a new thread with your specific board and debugger setup if none of those helped.
