nrfutil tool fails to read the .zip DFU package

AndyM

Hello . I saw this issue raised previously but with no resolution so here it is again

I built the smp-svr sample in VSCode with Zephyr SDK 2.6.1 which produced  a DFU package dfu_application.zip

I can successfully  update my device over BLE  with the Device Manager mobile app but nrfutil fails with the following error

./nrfutil.exe dfu ble -pkg /c/vd/samples/smp_svr/build-nrfdk/zephyr/dfu_application-.zip -ic NRF52 -p COM6 -a "EA:55:B0:DF:A9:6A"
Traceback (most recent call last):

File "click\core.py", line 1062, in main

File "nordicsemi\dfu\manifest.py", line 200, in from_json
KeyError: 'manifest'
[37460] Failed to execute script '__main__' due to unhandled exception!

I tried 

./nrfutil-6_12.exe pkg display /c/vd/samples/smp_svr/build-nrfdk/zephyr/dfu_application.zip with the same error

So appears that nrfutil fails to read the package

Looking through the forums I found one post that suggested to use the previous version of nrfutil. Tried 6.12 without success

Any ideas?

Thank you

    Hello,

    I believe the issue may be due to the format of the manifest.json files generated by Zephyr build and nrfutil. I tested this to confirm by examining the manifest generated by nrfutil, and it appears different from the dfu_application.zip manifest. I am attaching the generated zip file here. Please note that I did not include the key for signing during package generation, so it is not present in the generated manifest. I recommend trying to generate the package using nrfutil and using that package for DFU

    dfu_application_util.zip

    Kind Regards,
