A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header #167

I´m unable to upload the Configuration to my ESP32 board. I´m always getting the error message "A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header"

For some reason your development board is not responding to the command that should initialize the upload process. There is either a problem with the serial port connection or the board fails to boot in the flash mode.

Some development boards have a faulty reset circuit for selecting the boot mode automatically. If this is the problem you can perform the boot mode selection manually:

  1. Hold down the BOOT button
  2. Press and release the EN button
  3. Release the BOOT button
  4. Upload the project

Try googling with the exact phrase and you will get plenty of results.

See also the discussion in the ESP32 Arduino core project issues.

This is not a problem with this particular project. Unless you happen to have the SerialChiller board I can not provide general hardware debugging help as my time is limited.

It was much easier then i thought. Some people had to solder a bridge on their boards, i only had to hold the boot button when i pressed upload.

Nice to hear you got it working!
