Problem with Firebeetle 2 ESP32-S2

1. Connect the USB cable while pressing the Boot button.

2. Then delete the program with esptool.py.

You succeed once a twice. 

After that you will be able to write programs from the IDE.

This board does not have external IO0 used for bootstrap, so there is no way to force it into recovery mode. In the circuit diagram, IO0 is connected to K3, but it is actually IO47. It seems like a company that sells products without much evaluation.

I need correct schematic of that.

Here is a discussion regarding the same error message: https://forum.arduino.cc/t/a-fatal-error-occurred-failed-to-connect-to-esp32-no-serial-data-received/1071486

Thanks for this interesting advice.

I tried changing the port and pressing and holding the boot button and pressing the reset button than releasing both and still didn't work .I have no other cable for the moment.i'll buy another one later and i'll update u if there's anything

Hi!

1. It is recommended that check the data cable and computer‘s port.2. Pls press and hold the BOOT of ESP32S3, then press RST, and finally release the two buttons. Burn again after completion.
