USB/Jtag Debug on ESP32-C3 boards

Postby jnule1a » Tue Apr 19, 2022 2:42 pm

Hi everyone,
In doc https://docs.espressif.com/projects/esp ... w-it-works, Espressif states that in order to be able to use the on-board USB JTAG of the C3 chip, one needs a C3 revision 3 or newer. I am interested in buying the Lolin C3 mini orLilygo TTGO T-OI ESP32-C3 board. Do you know if the C3 on these boards has this revision ? By the way, the document also shows how to display this info.
In addition, do you have any experience using USB Jtag debugging with the C3 ?
Thank you in advance,
John

There's very few non-v3 chips made, so it would be super-unexpected to get a currently-made devboard with one on it.
