[Solved]Firmware upgrade tool for the Sequans Monarch SQN3330

[DDA]

Hi,
I was finally able to resolve the issue. The problem was with the SD card mount. The card would show successful mount , but for some reason would not show the *.dup file. I double checked my FAT32 format it looked right. Per suggestion from @jmarcelino, I formatted the card though the FiPy and then loaded the file and the issue was resolved:
The card directory was :

>>> import time
>>> import os
>>> from machine import SD
>>> sd=SD()
>>> os.mount(sd,'/sd')
>>> os.listdir('/sd')
[]
>>>

So tried the format :

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

After the format, and reload of the file the card directory showed as:

>>> import time
>>> import os
>>> from machine import SD
>>> sd=SD()
>>> os.mount(sd,'/sd')
>>> os.listdir('/sd')
['FIPY_GPY_CATM1_33988.dup']
>>>

Initial thread:
I followed the instruction per the link below and placed the codec.py, crc.py, sqnsupgrade.py, stp.py and README.md into VBS project space :

Per document : https://docs.pycom.io/chapter/tutorials/lte/firmware.html
Then I uploaded those files to my FiPy:

And , I also copied the firmware files : FIPY_GPY_CATM1_33988 and FIPY_GPY_NB1_35351 dup files into a recently formated FAT32 micro SD.
On executing

import sqnsupgrade

I get :

>>> import sqnsupgrade

  File "sqnsupgrade.py", line 7

I must be doing something wrong or reading in between the lines per the instructions. Thanks in advance!!

@dda
I think the project files hasn’t synced correctly. Please do, os.mkfs(“/flash”) to restore the board to a clean install and try syncing the project again.

[DDA]

@jmarcelino
Thank you for your response. I followed your instructions, ran

Connecting on COM25
>>> import os
>>> os.mkfs('/flash')

Then restarted Visual Studio Code and re-powered Fipy and Uploaded files:

Same as before, why is the import not working, the file is there and under the root directory itself. I also repeated the same by keeping the firmware files in a lib directory, same results.

@dda
Thank you.

What is the content of sqnsupgrade.py as shown in Visual Studio?

[DDA]

@jmarcelino
The content is about 1238 lines of code.

Umm that's definitely not right. Should be Python code.

Can you try downloading it again? It's better to download the whole project as Zip from Github and it pick it from there. I think you chose to save the webpage instead.

[DDA]

@jmarcelino
That was really a critical error on my part, I apologize . I have downloaded all the files again looks the same as on Git.
I have the two *.dup files under /sd directory in my microSD card.

>>>
sqnsupgrade.run('/sd/FIPY_GPY_CATM1_33988.dup', 921600)

@dda
Glad you got it going so far.

Are you saying you placed the files into a folder called sd on the SD card? That's actually not necessary, the files should be directly on the root folder.

The /sd is just a mount point for MicroPython

[DDA]

@jmarcelino
Now I get AT+SMSWBOOT=3,0 failed.
I removed the sd folder from the SD card, formatted it again to FAT32 and SD card now contains just the two *.dup files for CAT-M and NBIoT only on the root.

On executing the following from main.py or from REPL I get the error:

@dda
OK it's reading the files correctly. Can you try a couple more times? Make sure it's from a clean, freshly power up, start.

[DDA]

@jmarcelino
Ok repeated the following steps in order:

1. Ran os.mkfs('/flash')
2. Powered off Fipy/Expansion board 2.0
3. Took out SD card, formatted the SD card and reloaded the CATM 's dup file into it.
4. Powered Fipy on Expansion 3.0
   5 Started VSC software & Uploaded files

Tried about 4-5 times now and about 3-4 times earlier to you reply.

The FiPy is on a Expansion board 2.0 and powered via the USB connection to the PC.

[jmarcelino]

@dda
Ok thanks, can you let me know the output of

from network import LTE
lte = LTE()
lte.send_at_cmd('ATI')

Thanks

[jmarcelino]

@dda
Sorry just saw you're using the Expansion Board, have you removed the CTS and RTS jumpers from the board?

When using the expansion board with a FiPy, you will need to remove the CTS and RTS jumpers as these interfere with communication with the cellular modem.

https://docs.pycom.io/chapter/gettingstarted/connection/fipy.html

[DDA]

@jmarcelino
I took out the CTS and RTS jumper at the start itself, rest of the jumpers in place.
The unit is not responding to

lte=LTE()

its hangs up, first time it was stuck for over 3 minutes that's when I did Ctrl-C to get out of it. Tried again and its stuck again and won't respond to lte=LTE()

[jmarcelino]

@dda
So lte = LTE() doesn't respond? Even from power up?

If so please open a ticket with our service desk so we can best handle it.

@jmarcelino
Finally responding now after a few power-ups.
