On the Linaro debian build I have to do this

+       firmware-name = "wlan/prima/WCNSS_qcom_wlan_nv.bin";

On Debian I have to do this

Can you confirm that you're saying that you want below patch, which I
just merged?

https://lore.kernel.org/linux-remoteproc/20210312002441.3273183-1-bjorn.andersson@linaro.org/

(Which makes it possible to specify firmware name per platform/board)

Bjorn

The changes itself look good to me, but the commit message is really
misleading. It does not mention anywhere that the change actually just
enables "modem" on apq8016-sbc instead of "msm8916". :)

Also, WCNSS was actually enabled before already (with the default
firmware path). In my opinion, it would be clearer to change the
firmware-name for it in an extra patch.

How do I get a .mbn from the wcnss.{mdt,.b??} files provided in the
DB410c firmware package? I guess I should just run them through
https://github.com/andersson/pil-squasher?

Also, is the single file format (mbn) preferred now? Not sure if there
is any significant difference except having less files laying around.

Thanks,
Stephan

Same issue here, where can I get mbn file?,

After change the file to use wcnss.mdt this patch works.

You're right, I will rewrite the commit message.

Yes, .mdt + .bNN files can be put back together as a .mbn by running
them through the pil-squasher.

It's worth mentioning that the suffix doesn't matter for the loader, so
symlinking the .mdt to .mbn (in either way) will keep the kernel
happy - if that simplifies transitions in either way.

We've had numerous cases where people has managed to mix the parts from
different versions of the firmware, sometimes with the nice result of
the loader complaining that some particular .bNN file is missing
other times just with the signature check (mysteriously) failing.

Lumping the parts into a single .mbn resolves all these issues and
hence I prefer this. It is however not a requirement.

Bjorn
