Hi chegewara,

How can I flash a bootloader that could work with Arduino Ide or Platformio?

Im stucked. Thank you.

chegewara commented 2 years ago

What do you mean how to flash bootloader? You can do it with arduino IDE.

Actually I have a ESP32_S2_WOOR wich have a dip switch to select CH40 or USB native, but I can only flash trough the CH40 (serial converter), when Im traying to flash it with the Arduino Ide using USB native i get an error:

esptool.py v3.1 Serial port /dev/ttyACM0 Traceback (most recent call last:) .... .... .... BrokenPipeError: [Errno 32] Broken pipe

Previusly I Flashed my ESP32S2 with the dfu example but I think Im missing what I call "USB CDC bootloader" or something else.

Thank you.

When you want to flash over native USB you have to:

flash sketch that is using USB CDC example,
or use buttong to switch into bootloader mode
with my library dont use any option except Upload mode->internal USB

To make it works you have to use arduino-esp32 v2.0.0 (not alpha or RC) and latest tag from this library.
