#75955 Hi, sorry for the dealy, got a lot things in scholl to finish.

I made a mistake during the flashing the baord. Depending on what flash type is in the board, I just needed to add one flag:
Code: Select allsudo --port /dev/ttyUSB0 --baud 460800 write_flash --flash_mode=dio --flash_size=detect 0 ~/Downloads/esp8266-20180511-v1.9.4.bin

and it has solved my problems :)

Once an ESP can boot properly anything should run as it should.
Your output it giving a checksum error on the first board
Code: Select allcsum err
and the second board stops while loading the "room 12" section.

What happens if you flash the boards at a lower baud rate?
