user41608: I am trying to find the proper model of my esp32 MCU and find out the reason for below errors:
esptool.py v3.1-dev
Serial port /dev/ttyUSB0
Connecting........__
Chip is ESP32-D0WDQ6 (revision 1)
Features: WiFi, BT, Dual Core, Coding Scheme None
Crystal is 40MHz
MAC: 30:ae:a4:26:6f:44
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 921600
Changed.
Configuring flash size...

A fatal error occurred: Timed out waiting for packet content
A fatal error occurred: Timed out waiting for packet content


My ESP32 type and the board setting are shown below (link) :

Thanks.

user37622: In case where the upload procedure with esptool.py starts successfully but fails as soon as the baud rate is set to the high baud rate selected in Tools menu, select a lower baud rate in Tools menu.

user84622: This can also be caused by how certain pins are wired, if pin 12 is high at boot, programming will also fail with this message.
