Command for safe boot



  • Is it possible to do a safe boot (or a soft reboot) from the command line? I know that you can accomplish these with Ctrl+F and Ctrl+D, respectively, but I would like to include a safe boot in my script so I need a command line option. machine.reset() is a command line reset but it does a hard reset and I don't want main.py and boot.py to run.



  • @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.



  • @alexpul No, but it would be easy to add something like machine.safe_boot(). It would more or less only consist of the name definition, and a function with a single statement, which just calls another function.
