ESP32 Forum

hello ESP GEEKS,

I purchase few Xcluma Esp32 Boards.
While Flashing I am getting
Serial port COM12
Connecting........_____....._____....._____....._____....._____....._____....._____

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

But I am able to Connect to serial Port via PUTTY

Kindly Help
Thanks

hi
I could figure out.
This error is due
Not pressing the BOOT button while Flashing.

Thanks

On boards that exibit this problem I have found that soldering a 0.1uf cap from the EN pin to GND solves this problem.
