@alexpul But if it's only about not executing boot.py and main.py on boot, you can do similar with python scripts:
from machine import reset
def safe_boot.py()
# create a special main.py and reset
f= open("no_main.py", "w")
f.write('''import os\nos.remove("no_main.py")\n''')
f.close()
reset()
and then a specific boot.py, which checks for that special main.py:
import machine
import os
try:
f = open("no_main.py")
f.close()
machine.main("no_main.py")
except OSError:
# do the previous boot.py stuff here
Or something similar in you regular boot.py and main.py, which just checks for the existence of a flag for bypassing.
