Full modem firmware update doesn't recognize zip file

Hello Jens,

[quote user="Jens Cameron"]Is there any way you are aware of that we could test the embedded code before you fix this in some upcoming version?[/quote]

we have fixed the issue and a new release of pynrfjprog is scheduled for next week. The update can be triggered via:

pip3 install --user pynrfjprog

Until then, you might want to try to downgrade to an older version of pynrfjprog. I’m not sure if this will solve the issue, but you could try using the following commands (and step through older versions):

pip3 uninstall pynrfjprog
pip3 install --user -Iv pynrfjprog==10.13.0

Additionally, please be aware that the sample only works with Segger J-Link software up to version 6.88a on the DK.

NCSDK-9441: Fmfu SMP server sample is unstable with the newest J-Link version
Full modem serial update does not work on development kit with debugger chip version delivered with J-Link software > 6.88a

I hope this will help you!

Regards,

Markus

Hello Markus.

Nice that you could reproduce.

Is there any way you are aware of that we could test the embedded code before you fix this in some upcoming version?

I tried the GUI tools but it wouldn't conect through the serial port (need a Segger or Nordic USB port).

Some earlier version of command line tools or pynrfjprog perhaps?

Regards

Hello Jens,

[quote user=""]It seems the PC side does not recognize the zip file as parameter but tries to interpret it as a digest.[/quote]

thanks a lot for reporting this. I can reproduce the exact same behaviour in NCS v1.7.0. I will report this to our development team and keep you posted.

Regards,

Markus
