I have another cool example how to use USB on S2. This time its MSC class (mass storage) to OTA update device with drag n drop. Its enough to copy new binary to esp32 which works like a pendrive and new firmware will be flashed and start from OTA partition. Code is still messy, but for all who would...

You have to delete old version or to have second arduino IDE installation on windows and use this option to install:

Using Arduino IDE with the development repository

Yes, it is confirmed arduino bug. Thanks for reporting it.

This is big problem. esp-idf is supporting binary up to 3MB if i remember, for sure much less than 250MB.

Please dont say that out loud because someone may read it and believe it. Its NOT true.

You should check one more thing i forgot about. Check pin 2. Depending on flash chip on TTGO it needs to be pulled down or up, try to pull down first. I have custom PCB in hands and some UART device connected to pin 2 is pulling it up, which does not allow to flash it with this code: Serial port /de...

i see 2 options, maybe someone else can find more:
1) When I press Upload and also press and release the RST/EN and IO0 buttons during or before connection <-- this is not working
2) TTGO is not working
