Cellular radio firmware release (SQN3330) for both Cat-M1 and NB-IoT

[DDA]

@danielm
Could you shed some details on how you resolved the problem?? By manully mounting card-folder (/sd) using script via serial REPL?
I am having similar similar ussue:

Thanks a lot.

Hey Guys, I see this has been a problem for a few people and I have battled it for a few hours today. Initially, I was unable to get the firmware update to occur under any conditions. Always the same result:

<<< Welcome to the SQN3330 firmware updater >>>
Entering recovery mode
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/flash/lib/sqnsupgrade.py", line 100, in run
OSError: AT+SMSWBOOT=3,0 failed!
>>>

I have now performed the upgrade three times successfully and each time under slightly different conditions. Here's my setup:

• Pycom GPy (w/ firmware 1.17.5.b2)
• LTE antenna attached
• nano SIM for Telstra (Australia)
• Expansion Board 2.0
• SanDisk Ultra 16GB microSD card

Procedure:

• Remove all partitions from SD and format as single FAT32 partition
• Copy to SD, FIPY_GPY_CATM1_33988.dup from https://software.pycom.io/downloads/sequans.html. Check file size 5,533KB.
• Put SIM in GPy. Put SD card in Expansion Board 2.0. GPy on EB2.0
• Power from USB. Join Wi-Fi AP provided by GPy with password www.pycom.io.
• Create Atom IDE project folder. Use Settings - Project Settings to set Address: 192.168.4.1. Connect. Do not use Reset button: if reset is required, power down by unplugging, wait 10 seconds, reconnect.
• Use REPL to check contents of SD card:

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

• In the Atom project, create a 'lib' folder, add files from https://github.com/pycom/pycom-libraries/tree/master/lib/sqnsupgrade
• Synchonise with the microcontroller Ctrl-Alt-S
• Disconnect Atom IDE. Unplug GPy. Wait 10s. Reattach USB power. Reconnect Atom IDE, again, don't use Reset.
• Begin SQN3330 update at REPL per documentation:

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

• If successful, expect:

>>> import sqnsupgrade
>>> sqnsupgrade.run('/sd/FIPY_GPY_CATM1_33988.dup', 921600)
<<< Welcome to the SQN3330 firmware updater >>>

Upgrade completed!
Here's the current firmware version:
UE5.0.0.0c
LR5.1.1.0-33988
OK
>>>
>>>

Since the first update I also tried the above conditions with the following changes:

• Serial connection instead of Wi-Fi ... OK
• Expansion Board 3.0 instead of Expansion Board 2.0 ... OK

Honestly I think one of two things made the difference: Getting all the libraries loaded and the firmware image on the SD card before powering down. On first power up everything seemed to work the first time. If I reset, or if I'd had a failed attempt, only powering down and restarting made it work again.

The other option that might have had effect is doing the initial update using Expansion Board 2.0 (no firmware, FTDI only). Maybe once the first firmware update took hold subsequent updates were more likely to succeed.

Hoping that helps anyone still stuck with this. Chris.

Is the new NB1 firmware at https://software.pycom.io/downloads/sequans.html ready to use? Are there release notes detailing new feature support?

I tried to upgrade a GPY to FIPY_GPY_NB1-37365, but it stalled toward the end of the process. I waited about 30 minutes, then reset it. The previous NB1 firmware loads correctly. Any idea why it would hang at the final reset?

• Support of standalone mode of operation
• Support of Guard-band mode of operation
• Non IP PDN data delivery (NIDD)

@kevin hi! Same issue here. Did you manage to sort it out?
Cheers!

[flo242]

@danielm Would you happen to have any changelog for the new Cat-M1 firmware as well?
Thanks in advance!

[danielm]

@flo242
No, I asked Daniel Campora specifically regarding NB-IoT firmware. I suggest to contact him by email.

@danielm Thanks! Anything about band support?
