ESP8266- Undecoded Data (gibberish) in shell after flash

Post by astrong » Tue Feb 02, 2021 10:25 pm

Hi I have a LoLin ESP8266 NodeMcu v3 board,
I have flashed firmware esp8266-20200911-v1.13.bin onto the ESP8266 using the Thonny tool.
The board now has the led flashing rapidly and displays gibberish in the shell.

Can any one help find my problem

Most likely the wrong flash mode was used during flashing. The default is dio, but some boards need dout.
