Unable to update GPy modem firmware

[combaindeft]

@florianrdt said in Unable to update GPy modem firmware:

@combaindeft I can't try this because I can't initialize the LTE object. The comand freeze.

Step 1)

###
### STEP ONE
###
import pycom
print('LOG: pycom.lte_modem_en_on_boot() # to check, should be False')
print(pycom.lte_modem_en_on_boot()) # to check, should be False

print('LOG: pycom.lte_modem_en_on_boot(0) #set to False if above command is True')
print(pycom.lte_modem_en_on_boot(0)) #set to False if above command is True

print('LOG: pycom.lte_modem_en_on_boot() # to check again if change was made')
print(pycom.lte_modem_en_on_boot()) # to check again if change was made

Step 2)

• A) It is imperative that you do a "HARD" reset of the board!
  DO NOT PRESS THE "RESET" BUTTON ON THE BOARD

• B) To do a "HARD" reset:

  • Un-plug any battery source you might have attached!
  • Un-plug the USB-mini cable from the board
  • wait a few seconds
  • Re-attach the USB-mini to power up the device
  • continue to Step 3)

Step 3)

###
### STEP THREE
###
from network import LTE
lte = LTE()
lte.reset()
lte.disconnect()
lte.dettach()

# few AT commands to check if modem is alive and responsive
lte.send_at_cmd('AT') 
lte.send_at_cmd('ATI')
lte.send_at_cmd('ATZ')

If you got back your LTE() ... done the "Reset", "Disconnect" and "Dettach" ... and could execute the AT commands... continue to Step 3a) or 3b) in https://forum.pycom.io/topic/4022/unable-to-update-gpy-modem-firmware/24

from network import LTE
lte = LTE()

Thank you for your reply, but unfortunately the command freezes again.

import pycom
print(pycom.lte_modem_en_on_boot())

was already set to False.

@combaindeft Thanks a lot for the in-depth step-by-step walkthrough! I will try this tomorrow, when I get my NB-IoT SIM-card back and i will share if it works for me as well.

I really appreciate your help, thanks again!

@ktleh @wtrocel @Paul-Thornton @combaindeft
It works now for me as well!

So following the steps @combaindeft suggested did indeed result in a successful upgrade of the firmware.
One slight change: if using the upgdiff-file the updater.elf is not needed as @Paul-Thornton said, so for me (using an SD card)

sqnsupgrade.run('/sd/upgdiff_33080-to-40343.dup',  debug=True)

worked perfectly fine.
(Update paused at 96% for about 15 seconds as described in the guide at https://docs.pycom.io/tutorials/lte/firmware.html - whole upgrade took about 5-7 minutes)

So the whole process was:

>>> from network import LTE
>>> lte = LTE()
>>> import pycom
>>> print(pycom.lte_modem_en_on_boot())
False
>>> lte.reset()
>>> lte.disconnect()
>>> lte.dettach()
>>>
>>> lte.send_at_cmd('AT')
'\r\nOK\r\n'
>>> lte.send_at_cmd('ATI')
'\r\nSEQUANS Communications\r\nVZM20Q\r\n'
>>> lte.send_at_cmd('ATZ')
'\r\nOK\r\n'
>>> lte.reset()

Hard Reset

>>> from machine import SD
>>> sd = SD()
>>> os.mount(sd, '/sd')
>>> os.listdir('/sd')
['NB1-40343.dup', 'updater.elf', 'upgdiff_33080-to-40343.dup', 'upgdiff_38729-to-40343.dup']
>>> import sqnsupgrade
>>> sqnsupgrade.run('/sd/upgdiff_33080-to-40343.dup', debug=True)

This first upgrade took about 3-5 minutes -> it resulted in:

SYSTEM VERSION
==============
  FIRMWARE VERSION
    Bootloader0  : 5.1.1.0 [33080]
    Bootloader1  : 6.0.0.0 [40343]
    Bootloader2* : 5.1.1.0 [38638]
    NV Info      : 1.1,0,0
    Software     : 6.0.0.0 [40343] by robot-soft at 2018-11-07 13:57:00
    UE           : 6.0.0.0
  COMPONENTS
    ZSP0         : 1.0.99-3171
    ZSP1         : 1.0.98-3170

I then did the full update without using the differential file:

>>> time.sleep(5)
>>> sqnsupgrade.run('/sd/NB1-40343.dup', debug=True)
>>> sqnsupgrade.info()
<<< Welcome to the SQN3330 firmware updater [1.2.1] >>>
>>> FiPy with firmware version 1.18.1.r7
Your modem is in application mode. Here is the current version:
UE6.0.0.0
LR6.0.0.0-40343

Thousand thanks to @combaindeft again for the great hint with the LTE.disconnect/reset/dettach
This hint should be added to the renewed version of the upgrade guide.

hmm, if you can't do that ... then I think there is an issue with our board / modem ...

What is our "main board?" ... a PySense, PyTrack or PyScan? ... you are using with your GPy?

And ...

• did you update the firmware on the "main board"?
• did you update the firmware on the GPy?

As it's most recommended that you

• 1st - update the firmware on the "main board" to the latest
• 2nd - update the firmware on the "Logic board" .. GPy in your case ... to the latest stable version.

@bqpd

You are welcomed :-)

Was given a FiPY which had failed a modem upgrade. I have now tried almost every trick in the book and cannot get any life signs from the modem:

>>> import pycom
>>> print(pycom.lte_modem_en_on_boot())
False

>>> os.uname()
(sysname='FiPy', nodename='FiPy', release='1.18.1.r1', version='v1.8.6-849-b0520f1 on 2018-08-29', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1')

>>> sqnsupgrade.run('/sd/CATM1-39529.dup', '/sd/updater.elf', debug=True)

It is not possible to create a LTE() instance, the board simply hangs. Any ideas?

[combaindeft]

@redferne

A) Try the: Boot modes and safe boot

Hook it up to Board (PyTrack/PySense/Expansion/PyScan...) ... and shorten 3V3 + P12 with a wire for 7-9 sec ... and let go

B) Use the "upgdiff_33080-to*.dup" ... for the LTE-NB1 it is, and resp use the LTE-CATM1 version in the folder ...

sqnsupgrade.run('/sd/upgdiff_33080-to-40343.dup',  debug=True)

C) I haven't done this myself, but if I had the issue you have, I'd try to connect to the LTE-Modem by creating my own UART instance ...

https://docs.pycom.io/firmwareapi/pycom/machine/uart.html

Use the info from: https://github.com/pycom/pycom-micropython-sigfox/tree/master/esp32/lte

To figure out how to conf the UART instance ...

and lastly figure out how to send it the following AT_Command:

"AT!=\"setlpm airplane=1 enable=1\""

This will shut the modem down ... and after a Hard-reset (unplug everything, battery and usb-cable!) ... try to:

from network import LTE
lte = LTE()

and then run the firmware process ...

@bqpd Thank you!! I've managed to un-brick a FiPy and a GPy by following these instructions. Very much appreciated!

[grpatt]

@bqpd Thank you from the future.
