How to Flash ESP32-S2 / Wemos S2 mini v1.0.0 purple pcb with usb-c

[TD-er]

I will order those boards too, to have a test here and see why it may not enable the USB serial interface again.
I know the ESP32-S2 does have native USB support, so it may need to be set to announce itself as a serial device again to show logs etc.
I saw on AliExpress this board may have been pre-flashed using some MicroPython firmware, so I have no idea what that firmware may have done with some low level settings on the board.

yes I recognized this "firmware" and the device was not empty/blank at delivery. It also opened a drive in windows where some files are stored and can be seen.

Already did some research and made an issue for it: https://github.com/letscontrolit/ESPEasy/issues/4493

Was it a ready-made ESP32-S2 board or a custom-made board based on the ESP32-S2 chip? In case you've designed a custom-made board, there may be a hardware issue. You can post your design here for a review: https://www.pcbway.com/project/questionpublish

There are some ESP32-S2 boards that only activate the serial port when in Flash-mode. That is also the case with the OP of this thread, AFAICS.
An issue was opened at the Github repo to be able to enable/activate that serial port from ESPEasy.

The ESP32-S2 does have the option to start an USB device.
As a matter of fact, there are several possible.
But as described in the linked issue, it needs to actually start this USB device from within the firmware.
Other firmwares like Tasmota, do appear to have different builds for ESP32-S2 units which do need this and also for units that have an external USB to serial port on it.
