I am interested in this as well, especially if this is resolved:

The functionalities of USB Serial JTAG are not available, which will be supported in the future chip revision.

Do you have schematic of the board or (full) datasheet for Lontium LT8912B chip on that board?

According to Reddit Q3 2024.

Mine ESP32-C3-WROOM-02 module after delidding shows XMO 25qh32 SOIC-8 3V flash , so probably something like that but with more capacity. But note that if you use flash with different voltage you'll need to burn some efuses. Also components around that flash on WROOM module are tiny and knocking some...

Did you managed to fix it?
I am also trying to use interrupt (USB JTAG UART RX) on the ESP32-C3, also unsuccessful.

Maybe you are missing "idf.py add-dependency <component name>?"

I don't have Mac but it seems that your OpenOCD is compiled without ftdi support. Mine built from source on FreeBSD: esp32-openocd -c 'adapter list' Open On-Chip Debugger v0.12.0-esp32-20230921-194-g5a454ea9 (2023-12-22-08:44) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/do...

Are you using USB-C? If yes then you need 5.1k resistors on both CC lines.

I am using IDF 5.1 on FreeBSD 15-CURRENT. idf.py build/flash/monitor works. tools/idf_tools.py export --prefer-system also fails on my system but It seems that I don't need it. I also use port that you mentioned to build GCC. I have my IDF tools in path: PATH=$PATH:/usr/local/riscv32-esp-elf-idf51/b...

Hi, I am playing with ESP32-C3. Which function is used to put char on UART over USB/JTAG? From esp-idf/components/log/log.c esp_log_writev() uses (*s_log_print_func)(format, args) which is set to "vprintf" by default. Looking through sources I can't find that is set to something else. Following exec...
