Can't flash ESP32C3 on T-PicoC3
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.

ist nicht vorhanden oder das Board ist nicht angeschlossen
I see in ports: COM13( ESP32S3 Dev Module)
Why is this? Shouldn't it be ESP32C3???
Anyone with the same problem? (Or solution...;-)
- 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.
@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
