FiPy firmware upgrade failed - Cat M1

[ArnaudP]

Hello everyone.

I'm new to the Pycom community, so I apologise in advance if some of my questions may seem stupid.

I've just received a FiPy from which I'd like to use its CAT-M1 capabilities. I'm using it on top of a Pytrack module.
When trying to do a "From network import LTE", it failed to find LTE but I think it's because I need to upgrade my FiPy firmware. I have tried to do so following the tutorials found here :
https://core-electronics.com.au/tutorials/pycom-gpy-fipy-cellular-lte-firmware-update.html
And here :
https://docs.pycom.io/tutorials/lte/firmware

But I cannot get past the step where it says :

import sqnsupgrade
sqnsupgrade.uart(True)

As I get this message :

>>> import sqnsupgrade
>>> sqnsupgrade.uart(True)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'uart'

Could anyone please help me figure out what's the issue here and how I can resolve it? Thanks.

@john-baird Can you try this? https://forum.pycom.io/topic/4022/unable-to-update-gpy-modem-firmware/4

[John Baird]

@rskoniec Thanks for these detailed instructions. I've followed them and no longer get the Aborting error, however the process seems to fail:

>>> sqnsupgrade.run('/sd/CATM1-38638.dup','/sd/updater.elf')

Any suggestions?

Thanks!

@arnaudp I've been attempting to update the modem from UART no SD card. Haven't been able to do it.

[rskoniec]

@dda Download 1.18.1.r1 from here https://software.pycom.io/downloads/FiPy-1.18.1.r1.tar.gz and downgrade using Pycom Firmware Upate tool with flash from local file option.

I am on the same page with version r4:

>>> import os
>>> from machine import SD
>>> sd=SD()
>>> os.mount(sd,'/sd')
>>> os.listdir('/sd')
['upgdiff_38638-to-39529.dup', 'CATM1-39529.dup', 'upgdiff_33080-to-39529.dup', 'updater.elf']

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

Please advise on how I may be able to downgrade to 1.18.1.r1, so I may be successful....per post below.

@Xykon When I was helping @ArnaudP to resolve the problem with FiPy modem f/w update (sqnsupgrade.run('/sd/CATM1-version.dup', '/sd/updater.elf')) from initial release, we went this path:

• upgraded FiPy from 1.10.0.b1 to the latest stable 1.18.1.r4
• on FiPy 1.18.1.r4 modem f/w upgrade to the newest CATM1-39529 failed
• on FiPy 1.18.1.r4 modem f/w upgrade to previousCATM1-38638 failed
• downgraded FiPy from 1.18.1.r4 to 1.18.1.r1
• on FiPy 1.18.1.r1 modem f/w upgrade to CATM1-38638 successful
• now I'm waiting for @ArnaudP feedback about modem f/w upgrade to CATM1-39529 on FiPy 1.18.1.r4
• @ArnaudP has confirmed that after previous step, modem f/w upgrade to CATM1-39529 on FiPy 1.18.1.r4 was successful

What I've noticed is that updater.elf file in the previous CAT-M1/NB1 releases is the same and with a size of aprox. 300KB, but for the latest they are different for CAT-M1 (420KB) and NB1 (364KB). I've been told by @ArnaudP that he had already sent you a message.

[ArnaudP]

@rskoniec Sure, thanks :)

[rskoniec]

@arnaudp I've started a forum chat with you. Can we continue there?

[ArnaudP]

@rskoniec We haven't received our cat-M1 SIM card yet. Do you think I can try with a regular SIM ?
In this video tutorial : https://core-electronics.com.au/tutorials/pycom-gpy-fipy-cellular-lte-firmware-update.html
it seems he hasn't put a sim card in it. Weird. Or the video is a bit outdated maybe.

[rskoniec]

@arnaudp One more thing just came to my mind - do you have SIM card inserted in your FiPy? I don't know if this is an issue, but all of my FiPy modem f/w updates I've done with SIM card.

[ArnaudP]

@rskoniec
With some debug infos. We can see the files are listed with their right size :

File /sd/updater.elf has size 429340
File /sd/CATM1-39529.dup has size 6059510

Here is the complete log :

[ArnaudP]

@rskoniec Yup, that's the file I have on my disk, just checked the size with a freshly dowloaded version. It seems that it's the sending that didn't work. And now it says it won't detect the modem (perhaps because of faulty upgrade). Ok not anymore
But my files are the right ones on the disk :/

[rskoniec]

@arnaudp I think you've got incomplete file/files - 55498 bytes is too short (incomplete download from https://software.pycom.io/downloads/sequans2.html ?).

CATM1-39529.dup is almost 6MB big
updater.elf is over 400KB big

[ArnaudP]

@rskoniec Ok ! So I have formatted it again and now it works !

Now here's the new issue :

Attempting AT wakeup...

[rskoniec]

@arnaudp So maybe you should try with 8/16 GB SD card. FYI, os.mkfs(sd) is formatting your SD card to the right filesystem for Pycom devices. So after that you should remove SD card from PyTrack, put into your PC, copy files and then insert back again to the PyTrack, reset by button your FiPy and from fresh REPL:

from machine import SD
sd = SD()
os.mount(sd, '/sd')
os.listdir('/sd')         # to check if the files exist on SD card

import sqnsupgrade
sqnsupgrade.run('/sd/CATM1-39529.dup', '/sd/updater.elf')         # for CAT-M1
sqnsupgrade.run('/sd/NB1-40343.dup', '/sd/updater.elf')             # for CAT-NB1

[ArnaudP]

@rskoniec Same issue :

>>> os.mkfs(sd)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: the requested operation failed

[rskoniec]

@arnaudp Can you try:

os.mkfs(sd)

and then:

os.mount(sd, '/sd')
os.listdir('/sd') 

[ArnaudP]

@rskoniec Nope, here's what I get :

>>> from machine import SD
>>> sd = SD()
>>> os.mount(sd, '/sd')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: the requested operation failed

I wonder if it could come from the card? I only have at hand a 128Gb card (maybe too high capacity) ?
