I am using this ESP32-C3, which seems to be some strange chinese cloned board, and want to set up the step debugging in VS Code + PlatformIO.
First of all I was not able to find a board file in PlatformIO, but the Ai-Thinker ESP-C3-M1-I-Kit seems to be somehow close to it. But this page also tells the board is “IS NOT READY for debugging”, which I find strange as the ESP32-C3 should have JTAG exposed in its USB interface… At least this is how I read the datasheet. Any idea why this should not work?
Maybe someone can verify USB-JTAG debugging is possible with this MCU?
This is my current platformio.ini file
[env:esp32-c3-m1i-kit]
platform = espressif32
board = esp32-c3-m1i-kit
framework = arduino
monitor_speed = 115200
debug_tool = custom
debug_port= localhost:3333
debug_server = pio pkg exec -p tool-openocd-esp32 -- openocd -f board/esp32c3-builtin.cfg
debug_init_break = setup
I did clone and install openocd from the espressif fork. In VSCode, when I click Platformio > Debug I get a lot yellow prompt followed by this error:

nerdyscout@tuxedo:/home/nerdyscout $ whereis openocd
openocd: /usr/local/bin/openocd
nerdyscout@tuxedo:/home/nerdyscout $ echo $PATH
/home/nerdyscout/.local/bin/esp-idf/tools:/home/nerdyscout/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/nerdyscout/.oh-my-zsh/custom/plugins/fzf-zsh-plugin/bin:/home/nerdyscout/.fzf/bin
So it seems like openocd can not correct found, but I belive my PATH is set up correct.
