I'm using the NodeMCU Amica board. I erased the flash on the ESP8266 using...
sudo esptool.py --port /dev/ttyUSB0 erase_flash
I then wrote the flash using the following command...
sudo esptool.py --port /dev/ttyUSB0 write_flash --flash_size=detect 0 esp8266-20210418-v1.15.bin
I then used minicom to serial into the device. I tried both 9600 baud and 115200 baud. Neither worked. Specifically, I kept pressing enter and the REPL prompt did not appear. Please help!
I have asked on another forum and they have pointed me here.

Re: Can't Serial into MicroPython ESP8266
Hi... in my test I found I had to run minicom with sudo to get access to the serial port. There is a ways to enable it for all users so that sudo is not needed but I have not researched it yet. That might be the issue.
