L01 does not run boot.py or main.py



  • Hi all!
    I've another strange thing. My L01 devices does not run boot.py or main.py after power up or reset. I uploaded very simple test files.
    boot.py:

    from machine import UART
    import machine
    import uos
    
    usb = UART(0, baudrate=115200)
    os.dupterm(usb)
    
    print('running boot.py')
    
    uos.uname()
    

    main.py:

    print("running main.py")
    x = 0
    for y in range(0, 9):
        x += 1
        print(x)
    

    A Lopy on Expansionboard 2.1a gives me:

    My L01 on my custom baseboard and also connected on a Expansionboard 2.1a gives me:

    What means this "ho 0 tail 12 room 4"?

    I can run boot.py or main.py on the L01 manually:

    >>>
    running boot.py
    (sysname='LoPy', nodename='LoPy', release='1.7.0.b1', version='v1.8.6-620-g3812d902 on 2017-05-24', machine='LoPy with ESP32', lorawan='1.0.0')

    I checked with FTP that the files are there and not corrupted. Everything seems to be fine.

    Any suggestions??

    Cheers,
