problems updating sqns firmware



  • i'm trying to get the newest firmware on the LTE modem of the fipy
    but when i do this : sqnsupgrade.run('/sd/FIPY_NB1_37781.dup')

    i get :

      File "<stdin>", line 1, in <module>
      File "/flash/lib/sqnsupgrade.py", line 106, in run
    OSError: [Errno 2] ENOENT
    

    this is the firmware running on the fipy
    Pycom MicroPython 1.18.0 [v1.8.6-849-046b350] on 2018-06-01; FiPy with ESP32
    i downloaded the updated versions of the pycom libraries today.

    i tried formatting the SD card but that doesn't help

    any thoughts?



  • getting further on this problem
    found list of OSErrors ENOENT means No such file or directory

    there was a typo in the file path

    at this point i'm getting other errors at line 121

    >>> sqnsupgrade.run('/sd/FIPY_GPY_NB1_37781.dup',921600)
    <<< Welcome to the SQN3330 firmware updater >>>
    Entering recovery mode
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/flash/lib/sqnsupgrade.py", line 121, in run
    TypeError: extra keyword arguments given
    >>> 
    

    reading the sqnsupgrade.py says that the line does

    print('Resetting.', end='', flush=True)
    

    guessing it is not important that to print something i removed the line
    running the upgrade again gives me this

    >>> sqnsupgrade.run('/sd/FIPY_GPY_NB1_37781.dup',921600)
    <<< Welcome to the SQN3330 firmware updater >>>
    Entering recovery mode
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/flash/lib/sqnsupgrade.py", line 123, in run
      File "/flash/lib/sqnsupgrade.py", line 74, in wait_for_modem
    TypeError: extra keyword arguments given
    

    reading the code at that line 74 gives

    print('.', end='', flush=True)
    

    this makes me think that there is something wrong with the call of the print() function

    so i removed the

    flush=True
    

    from both lines. after running the sqnsupgrade i now get the following

    >>> sqnsupgrade.run('/sd/FIPY_GPY_NB1_37781.dup',921600)
    <<< Welcome to the SQN3330 firmware updater >>>
    Entering recovery mode
    Resetting..
    
    Starting STP (DO NOT DISCONNECT POWER!!!)
    STP started
    Session opened: version 1, max transfer 8192 bytes
    Code download failed, aborting!
    >>> 
    

    this is how far i am at he moment still looking in to this
    any help is appreciated

    edit:

    after some more trying got some more info
    if i try the update again i get this error

    >>> sqnsupgrade.run('/sd/FIPY_GPY_NB1_37781.dup',921600)
    <<< Welcome to the SQN3330 firmware updater >>>
    Entering recovery mode
    AT+SMSWBOOT=3,0 response b''
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/flash/lib/sqnsupgrade.py", line 131, in run
    OSError: AT+SMSWBOOT=3,0 failed!
    
    

    the modem is not responsive to any AT commands
    if i send just AT+CGMI i get ERROR

    i tried to locate the cause of the error of the code download
    i eddited the sqnsupgrade.py to find out where this error is generated
    it is in line 155

    except:
            blob.close()
            print('Code download failed 2, aborting!')
            abort = True
    

    i'm really out of ideas for the moment



  • yes i did

    the new sqnsupgrade.py file does that too by the way on line 87 so i figure it isn't needed to do that.

    also tried with mounting doesn't make a difference



  • @eric-waai just checking, did you mount the SD device ?
