Warnings when creating the `spk` file with Modem Firmware from Firmware 15.1 Components

Legato Linux distribution (Yocto project)
1

I am trying to create base images for WP7702 devices in a production environment using the following components derived form the Firmware 15.1 (FW 15.1) release:

  • appsboot_wp77xx.cwe
    generated from yocto distro from FW 15.1, assuming bootloader
  • yocto_wp77xx.4k.cwe
    generated from yocto from FW 15.1, assuming kernel and rootfs
  • legato-squashfs.ubi.cwe
    downloaded from FW 15.1, assuming legato host tools
  • 9999999_9907618_SWI9X06Y_02.36.08.09_00_GENERIC_001.079_000.spk
    downloaded from FW 15.1, assuming the generic, closed-source modem firmware

When I try to bundle these components into a spk file, i get the error below. If i remove the modem firmware file from the arguments, the spk files builds without errors.

My question is: Is the error correct? If yes, how do I include modem firmware updates to my target? If no, how do i know to ignore this and future errors like it?

swicwe -o my-image.spk -c ./build_bin/tmp/deploy/images/swi-mdm9x28-wp/yocto_wp77xx.4k.cwe ./build_bin/tmp/deploy/images/swi-mdm9x28-wp/appsboot_wp77xx.cwe ./legato-squashfs.ubi.cwe ./9999999_9907618_SWI9X06Y_02.36.08.09_00_GENERIC_001.079_000.spk

does it work if you download the combined spk without modem image to module?
Does it work if you download the combined spk with modem image to module?

Have you tried to combine all official image with swicwe and download to module to test?

This is reproduceable using the official files in Firmware 15.1 page (see below).

Not sure, as I don’t see those file in the FW 15.1 Components page. I also don’t think that will help with my core issue.

If the combined spk with or without modem image is working fine in module, that means those warning message is not important

Sorry, but I am going to have to escalate this issue through my WP distributor. Your tools needs to correctly alert when they are making a package that may harm or not update a certain aspect of the device. I do not want my team to get used to ignoring this warning only to brick devices when it correctly triggers in the future.

Also there are two sets of model numbers: the WP series (wp77, wp76. etc.) and the Product ID. The Product ID is referenced above (Y921, Y931, 9X06, 9X28 ) and in the image generation (bitbake mdm9x28-image-minimal). Is there documentation mapping this two sets of identifiers?

Probably you need to ask your distributor
