Hello,

Were you able to successfully generate the package using nRFutil?

Kind regards,

Thank you for verifying. Could a ticket be opened to fix this going forward?

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

Kind Regards,

Yes, initially I was using the latest nrfutil tool from your website. It has version 7.13.0

Yes, I am trying to perform BLE DFU with the dfu_application.zip file that was generated as part of the smp_svr sample build. This package is recognized by the Device Manager mobile app and I was able to run BLE DFU successfully with it. Are you saying nrfutil does not support the manifest format generated by the Zephyr build?

Here is the manifest from dfu_application.zip

Hello,

Could you please let me know which version of nrfUtil you were using initially (before downgrading)? I recommend using version 7.0.

I am not entirely sure, but are you trying to perform BLE DFU with the generated dfu_package.zip inside the build/zephyr folder? If so, the error might be due to the manifest file within the dfu_application.zip file.

I recommend generating the zip file using the command nrfutil pkg generate. Please follow the instructions on this page for generating the zip file and then proceed with the steps outlined in the "Performing a DFU" section.

Kind regards,

Abhijith
