Can't flash ESP32C3 on T-PicoC3

ulihuber

Hi,
I am trying to flash software to the ESP32C3 section of the T-PicoC3. No success. I am using Arduino and have no problems with other controllers like ESP32 Dev module. I can also build and flash Pico software on the T-PicoC3 but flashing of the ESP32C3 controller does not work.

Traceback (most recent call last):
esptool.py v3.3

I see in ports: COM13( ESP32S3 Dev Module)
Why is this? Shouldn't it be ESP32C3???

Anyone with the same problem? (Or solution...;-)

Steps:

Use tweezers to short IO9 to GND (because ESP32C3 already has firmware by default, it needs to enter BOOT state)
Link USB (note that the positive and negative plugs select ESP32C3)
Normal upload procedure

Has anyone been able to program the ESP32 using Arduino? I'm following the directions at https://github.com/Xinyuan-LilyGO/T-PicoC3, but when I enter the Arduino Boards Manager and type "EPS32C3 Dev" into the search box, nothing is returned.

Thanks,

A.J.

@ajlenze Only ESP32 can be found in the Arduino Boards Manager. You need to install ESP32. And C3 is a derivative of ESP32. After installing ESP32, you can select the C3 subclass chip in the board
