ampy no longer connecting

Question

I had ampy working for a while. It was intermittent after that, and now it doesn't work most of the time. I'm able to run esptool.py --port COM3 flash_id and esptool.py --port COM3 chip_id , but when I try to run ampy --port COM3 ls or ampy --port COM3 run test.py it just hangs.

I've tried:

• Restarting computer
• Shutting down computer
• Different USB ports
• Different ESP32s and ESP8266s

Any ideas?

Answer 1

I learned that different devices in the same family need to be flashed differently. I was flashing MicroPython with ESP-Now on a Wemos D1 Mini using:

esptool.py --chip esp8266 --port COM11 write_flash -z 0x1000 C:\Users\Main\Downloads\firmware-esp8266-GENERIC.bin

and it should have been:

esptool.py --port COM11 --baud 1000000 write_flash --flash_size=4MB -fm dio 0 C:\Users\Main\Downloads\firmware-esp8266-GENERIC.bin
