<![CDATA[FiPy firmware upgrade failed - Cat M1]]>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.

It's still not working but digging into the GitHub repo, it seems that the commands that are described in the tutorial : https://docs.pycom.io/tutorials/lte/firmware uses methods (sqnsupgrade.uart , sqnsupgrade.run , ...) that worked only with an older version of the code. Can anyone confirm ?

Has anyone attempted to upgrade its modem recently?

Thanks in advance.

  • FiPy (v1.18.1.r3) + PyTrack (v0.0.8) upgrade modem f/w to CATM1-39529
  • FiPy (v1.18.1.r4) + PyTrack (v0.0.8) upgrade modem f/w to NB1-40343

I've put .dup and .elf files on the SD card root folder and use below instructions:

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

Which version of f/w do you have on your FiPy?

I get this when I make a os.uname() :
(sysname='FiPy', nodename='FiPy', release='1.10.0.b1', version='v1.8.6-834-g5677703c on 2017-11-13', machine='FiPy with ESP32', lorawan='1.0.0')

Is that the information you were asking?
As for

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

The system tells me that it doesn't know a method by the name "run". Which is odd since it's in the code of sqnsupgrade.py
I've been issuing these commands from the Pycom Console. Is it ok or should it be in main.py ?

Once again, thanks for your reply.

Download Pycom Firmware Update for your platform (Windows, macOS, Linux) and make a FiPy f/w update to the newest stable version. After that you should be able to upgrade FiPy modem f/w with my procedure and be patient, because it'll take a while.

I've put your code in main.py, copied the necesarry files on a SD card and began the update process. Maybe putting it in main rather than typing the commands myself was a bad idea because I have no idea if the update process is running. I guess something is happening since I can't connonect on the pycom console.
So I guess I'll wait and see if something is happening.

Is the heartbeat suppose to resume once the update process is over? If not, how I'll know when I can remove the power?

Connect your PC to the FiPy through the microUSB of PyTrack module and use for example PuTTY to connect to VCP (Virtual COM Port) and execute my instructions one by one.

Be sure that your boot.py have these lines:

from machine import UART
import os
uart = UART(0, 115200)
os.dupterm(uart)

Your main.py for safety should be empty or renamed (main_off.py).

With heartbeat when pycom.heartbeat_on_boot(0) is set then it won't work after FiPy restarts.

I had uploaded this (and forgot a boot.py) and now I can't get a REPL console.
I hope I did not brick it....

Do you know by any chance how I can reset the board so I can connect to it and upload the correct files ?
Sorry and thank you for helping me.

How long is it going now? Do you have WiFi connectivity in your boot.py/main.py files to try telnet connection? There is also something like Safe Boot.

So now I'm trying your commands. And here what I giet for :

>>> os.mount(sd, '/sd')
Traceback (most recent call last):

import os
os.uname()

Btw, I've upvoted your posts so maybe your posts delay has gone - check it out.

(sysname='FiPy', nodename='FiPy', release='1.18.1.r4', version='v1.8.6-849-dfa1176 on 2018-11-12', machine='FiPy with ESP32', lorawan='1.0.2', sigfox='1.0.1')

1.18.1.r4 seems on it.
Thank you, that's very kind of you. I you can read this message, it'll mean it succeeded to post ;).

I'm going to try to format my sd card again. Could that be an issue with it or is it necessarily on the side of the fipy firmware itself?

from machine import SD
sd = SD()
os.mount(sd, '/sd')
os.listdir('/sd')

do you get your modem upgrade files listed?

]]>https://forum.pycom.io/post/23564https://forum.pycom.io/post/23564Thu, 15 Nov 2018 15:35:06 GMT<![CDATA[Reply to FiPy firmware upgrade failed - Cat M1 on Thu, 15 Nov 2018 15:37:38 GMT]]>@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) ?

os.mkfs(sd)

and then:

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

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

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

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 :/

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.

  • 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.
