Flashing ESP32

Postby Nikosant03 » Thu May 13, 2021 7:30 am

Hi everyone,

I want to intergrate the ESP32-S2-MINI module into my design. Can I use the JTAG interface for debugging and flashing as well? If JTAG serves both features do I need to include USB connector and USB to UART Bridge?

Thanks

JTAG can be used to both program and debug:

Well that is up to you.
JTAG is relatively expensive and not exactly consumer gear.
(1) you could use another style of connector, (2) reprogram over Wifi, (3) reprogram over USB, (4) have a programming dongle.

It depends on your use case.
Serial is cheap but for consumer reprogramming USB may be easiest.
If you go USB make sure your PSU can handle the card.
& I also believe that IDF CAN should be fixed.
