FiPy firmware upgrade failed - Cat M1
-
@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 Or the video is a bit outdated maybe. -
@arnaudp I've started a forum chat with you. Can we continue there?
-
@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.b1to the latest stable1.18.1.r4 - on FiPy
1.18.1.r4modem f/w upgrade to the newestCATM1-39529failed - on FiPy
1.18.1.r4modem f/w upgrade to previousCATM1-38638failed - downgraded FiPy from
1.18.1.r4to1.18.1.r1 - on FiPy
1.18.1.r1modem f/w upgrade toCATM1-38638successful now I'm waiting for @ArnaudP feedback about modem f/w upgrade toCATM1-39529on FiPy1.18.1.r4- @ArnaudP has confirmed that after previous step, modem f/w upgrade to
CATM1-39529on FiPy1.18.1.r4was successful
What I've noticed is that
updater.elffile 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.The machine is working as good as it's code.

I am on the same page with version r4:

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

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