FiPy firmware upgrade failed - Cat M1

[rskoniec]

@arnaudp Do not do this by main.py please - you should use USB UART REPL. 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.

@rskoniec Indeed, it seems it may have been a bad idea. 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.

[rskoniec]

@arnaudp Did you try anything after you start upgrade (reset button)? 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.

[ArnaudP]

@rskoniec Oh thank you ! I was able to safe boot into it. I was afraid I had bricked my device.
So now I'm trying your commands. And here what I giet for :

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

Sorry for the delay between the messages, I'm allowed only one message every 10 minutes on thsi forum.

[rskoniec]

@arnaudp Did you verify your FiPy f/w version after the update?

import os
os.uname()

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

[ArnaudP]

@rskoniec Yup, I had checked it, here's the update :

(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?

[rskoniec]

@arnaudp OK, perfect. If you try:

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

do you get your modem upgrade files listed?

[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) ?

[rskoniec]

@arnaudp Can you try:

os.mkfs(sd)

and then:

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

[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 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 Ok ! So I have formatted it again and now it works !

Now here's the new issue :

[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 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 :/

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

[ArnaudP]

@rskoniec Sure, thanks :)

@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.
