ESPtool not releasing serial port
Posted: Wed Jun 08, 2022 2:52 pm
Flash with ESPtool no problem but mpremote won't run...
if I comment out ESPtool then mpremote runs fine.
ESPtool hangs on to COM Port , how to release ?
Close serial port before exit from main() #316
From <https://github.com/espressif/esptool/pull/316>
Release COM port when flash process is finished #37
From <https://github.com/marcelstoer/nodemcu- ... /issues/37>
Why is the serial port still open when killing a subprocess?

print('mimic Flash')
arg1 = ['--port', 'COM13', 'flash_id']
esptool.main(arg1)
print('copy files')
arg2 = 'mpremote connect COM13 cp assets/boot.py assets/main.py :'
sub = subprocess.Popen(arg2, stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True)
