ESp32-s2-lipo - Cannot load program

[vegethalia]

Hi,

Silly question... I'm unable to put the board into "load mode", I do the "hold btn1 - press reset/release reset - release btn1" procedure and the rgb led stops blinking. But then I try to upload the compiled firmware and it doesnt work. Probably I'm missing something trivial, but I don't know what it is.

I'm using PlatformIO with the required patches to compile for esp32-s2 SAOLA (and the program compiles and links just fine).

The COM port is correct (I can monitor the output of the default loaded script of the blinking led).

Please, any ideas...

Ok I found the solution... I had to change the usb drivers detected by windows and use the correct one for the CH340 chip.
Silly me I thought that windows would have installed the correct one automatically... ¯\_(ツ)_/¯

Thank you for the update. Yes, our board uses CH340T while Saola has CP210x chip. These require different drivers.
