Re: TUMPA and JTAG

Hi, have you double checked the JTAG PIN connection? Attached you will find my cabling (esp32 DEV C). I am not using this entry in the config: esp32 flashbootstrap 1.8 HTH br Patrick Thanks for posting your setup. Now I'm quite certain my wiring and jumper settings are correct. Perhaps my TUMPA is ...
