USB-JTAG AT Command FW

[GiulioDallaVecchia]

Hi espressif community,

I'm using esp32-C3-mini1. I flashed the official AT command firmware to the module, but after that I can't re-flash any other firmware using USB-JTAG build-in. When I try to connect with openocd I always receive an error.

I've already tried to do that with the "hello world" project and I don't receive any error when I try to connect the board with openocd after flashed the code. It seems that the AT command firmware reconfigure the GPIO that are used for USB-JTAG connection. Is it possibile?

Thanks a lot in andvance.

Yes, I seme to recall it does that. A fix would be to pull GPIO9 low and reset the chip - that resets it into download mode, allowing you to send a new app.
