A few days ago I have flashed my 4 boards(nodemcu/lolin) with the MicroPython firmware. Everything passed without any issues until I have started accessing the boards with picocom(alternative to screen software)...
The first to boards responded without problems, I was able to get python console and execute python commands, also I was able to upload scripts and make them bootable(to be called main.py). But problem occurred with third and fourth boards. I was able to flash them without problems, but when I tried to access them in order to get python console, the picocom was stuck, no response form the board.
To be sure that I have not made any mistake or bricked the boards, I have uploaded arduino blink sketch, and got working board with blinking LED.
Again, I have flashed both boards according to the adafruit guide. Flashing passed without issues, I have tried to access with Picocom and got the same problem from the beginning of this post.
Does anybody know what is wrong with the boards or am I doing something wrong?
Please help me to solve this issue...
