Can't Serial into MicroPython ESP8266
Posted: Sun May 30, 2021 4:49 pm
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!
