Modem Firmware Update

jaredwolff

Hi cchoi22915, yup the mfw_update sample is for standalone upgrades. (No programmer or dev kit necessary)

jaredwolff

@cchoi22915 I assume you’re following the directions from here? https://docs.jaredwolff.com/nrf9160-managing-mfw.html

cchoi22915

jaredwolff Yes that is correct. I am able to run other code successfully (such as AT_Client) Here is the full error log:

cchoi22915 can you install the CLI tools from Nordic and try again?

cchoi22915

I have uninstalled and installed practically everything (even restarting my computer in between). I wonder if there is a way for me to download NRFDFU.dll separately? Although there appears to be a bigger issue at hand
.

cchoi22915

jaredwolff no joy, the same thing occurs

jaredwolff

I think originally that DLL was packaged with the Python module but that may have changed recently. I know other people in the community are having similar problems.

cchoi22915

jaredwolff Hmm, I wonder if I can go to a really old version

jaredwolff

cchoi22915 looks like you’re using power shell. Can you try from cmd.exe instead?

cchoi22915

jaredwolff Ran the same command in cmd.exe with admin rights and the same issue occurs

jaredwolff

What type of system are you running on cchoi22915 ? (OS and Architecture)

jaredwolff

What version of python do you have installed?

cchoi22915

jaredwolff 3.10.4

cchoi22915

jaredwolff I am running Windows 11 ×64

jaredwolff

Hmmmmm. I have a feeling it may have something to do with the Python install. Hard to say. There’s nothing on the repo that states you can’t use the latest/3.10.

https://github.com/NordicSemiconductor/pynrfjprog

Have you tried downgrading and using something like Python 3.7?

cchoi22915

That is one thing I have not tried downgrading yet. I am currently creating an Ubuntu VM to see if it is an OS related issue. I will try to downgrade python and also try Linux to see how this fairs.

jaredwolff

cchoi22915 sounds good. Sorry this is a pain.

cchoi22915

jaredwolff no worries, thank you for helping. I will update on how it goes

cchoi22915

jaredwolff Whoops, forgot to update this thread, but the issue continued to occur when I tried this in Linux. I was, however, able to follow the steps in LINK TO FORUM PAGE and successfully update the modem firmware.

jaredwolff

That’s awesome! Thanks for letting me know cchoi22915
