How do I verify that I'm running latest-n-greatest?

@Ed-Sutter I see what you're saying. In order to add the VID/PID then we would have to patch qmi_wwan which we've done for other modems and integrate it into https://gitlab.com/voxl-public/system-image-build/meta-voxl.
If you look through meta-voxl you'll see some other modem related patches we've done in the past, e.g.: https://gitlab.com/voxl-public/system-image-build/meta-voxl/-/blob/master/recipes-kernel/linux-quic/files/qmi_wwan2.patch
What I would do is run through voxl-build without making any changes. Once it gets past the patching step you should now be able to see the post-patched qmi_wwan.c file and can create another patch based off of that file to then add to meta-voxl.
@tom I was able to look at the post-patched qmi_wwan.c file and it does have the VID/PID in there. I just don't know for sure if that patch is in the platform build that I just installed (actually, I'm hoping its not because the latest build doesn't fix my problem).
This is what is running on my machine now.../ # voxl-version -------------------------------------------------------------------------------- system-image: 3.8.0 kernel: #1 SMP PREEMPT Tue Apr 26 18:08:39 UTC 2022 3.18.71-perf -------------------------------------------------------------------------------- hw version: VOXL -------------------------------------------------------------------------------- voxl-suite: 0.7.0 --------------------------------------------------------------------------------If that patch is not part of this package (which appears to be 6 months old), then I'd like to know how I can pull that patch in.
If on the other hand, its already in this package, then I don't have a clue what to do about my modem issue. -
@Ed-Sutter Okay cool, well in that case I would recommend building the kernel using
voxl-build, flashing the kernel, and seeing if there is a difference in performance.@tom Ok I did that but now I'm scared...
I had built the kernel yesterday, so I ran through the steps in "Testing the Kernel Before Flashing" and everything checked out (the timestamp changed).
I then followed the steps in "Flashing the Kernel", got this output:$: fastboot flash boot /opt/data/workspace/poky/build/tmp-glibc/deploy/images/apq8096-drone/apq8096-boot. img target reported max download size of 536870912 bytes sending 'boot' (56096 KB)... OKAY [ 1.551s] writing 'boot'... OKAY [ 0.429s] finished. total time: 1.980sbut then typed adb devices and got this output:
$: adb devices List of devices attached $:I have not reset or power-cycled anything yet. Should I do that?
-
@Ed-Sutter Yeah you have to reboot or run
fastboot reboot, it's still in fastboot mode. For example it'll probably show up withfastboot devices -
@Ed-Sutter Great! I updated the README to make that step more clear.

@Ed-Sutter Hmm not too sure where to go from here other than contact Sierra for ideas.
In the past we've used scripts that run in the background that monitor a network connection and re-enables the connection if it drops off, that might be the route to go.
It would be a modified version of something like this: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/scripts/modallink_relink.py

Apologies for highjacking the thread and being a noob, but @Ed-Sutter are you able to build a system image from https://gitlab.com/voxl-public/system-image-build/meta-voxl ?
Or is this the kernel only that you then install ontop of an existing system image?

@Steve-Turner voxl-build allows you to build the kernel only which you can then flash on top of an existing system. Qualcomm licenses are required in order to build a full system image.
