I'm trying to flash my Adafruit HUZZA Feather.
Using the ESPFlasher tool ( not python) and the nodemcu cloud service https://nodemcu-build.com/
It always flashes without error (log file) without error (log file) but after restart, the blue LED is flashing frantically and the serial port spits out hieroglyphs without stopping. Reset, same.. only a Reset with grounded GPIO0 will stop it.
After flashing the image 5 or six times it finally DID work.
Then I realized I missed to add the PWM module.
Now I am at the same spot again with the flashing LED and it has not come back to normal life again..
I will try the Python tool. but maybe somebody here has an idea.
