ESP32-C3 JTAG/USB

Postby Stipa88 » Wed Apr 12, 2023 12:23 pm

Hello everyone.

I am using ESP32-C3-MINI-1, on my own project.

By default, the D+ and D- (USB) lines are used internally for programming/debugging.
Can I use the USB lines for my project, without permanently programming the bits inside the "fuse" register.

I don't want to permanently disable JTAG/USB debugging while I'm in product development.
If possible, how to do it ?

Tnx

Yes, you can simply reconfigure those GPIOs in your program. Note that when you do that,the USB-serial-JTAG doesn't work anymore until you reset the ESP32C3.
