micropython core esp32 c3

[icelon]

hello ||
, I have acquired a board type esp32 c3 core (attached photo) and I cannot make it work, the whole process works correctly, only when I add it to the ide thonny it does not detect the interpreter, I have used the commands that are on the page where to download the firmware, I would appreciate any help on how to make it work

The picture of the board is not very clear, but there might be a USB/UART bridge there. You could try the UART version of the firmware from https://micropython.org/download/esp32c3/

Yes, it looks like a CP2102 on theboard. Did you try to install the other firmware, the non-USB version?

[gitmun]

yes, and it still doesn't work

[icelon]

ummm it's a CH343P .... I'll look around to see but it doesn't go with any compilation of esp32-c3

[robert-hh]

Just another USB/UART bridge. It does not require a special compile variant of the ESP32C3, besides serial REPL. I do not expect it to need a specific driver for Linux. When the board is connected, does it register as /dev/ttyACMx or /dev/ttyUSBx? Your log shows /dev/ttyACM0, which is unusual for a USB/UART bridge,

[gitmun]

Yes is ttyacm0...

[robert-hh]

That's a little bit surprising. The boards with CH340 I have come up as /dev/ttyUSBx. But the CH343 may register differently, and the firmware upload works apparently with that device. Do you use plain Linux of Windows-WSL?
What happens if you use mpremote or picocom -b 115200 /dev/ttyACM0 as terminal emulator instead of rshell?

So it works!
