I was indeed told a while ago that there was a limited number of KBL-based devices with DMIC, but mistakenly assumed we could avoid dealing with this configuration and Murphy's Law applied of course. we'll have to huddle with our Intel colleagues to figure this one out.
OK, thanks.
Is there any update on the release of signed firmware files for the other platforms? We are under pressure to return the other unit we have to the vendor (which needs the cnl files), but we would like to try SOF first.
Apologies for the delay, I hurt my back and was off work for a few weeks. Signed binaries now on v1.3 github release tag. Will now be upstreaming into Linux FW repo.
Liam, the sizes of signed firmware binaries are a lot different than the unsigned ones (v1.3 tag) which I can build in docker:
-rw-rw-r--. 1 perex perex 270336 Jul 24 15:44 sof-apl-signed-intel.ri -rw-r--r--. 1 perex perex 167936 Jul 24 15:44 sof-apl.ri -rw-rw-r--. 1 perex perex 278528 Jul 24 15:44 sof-cnl-signed-intel.ri -rw-r--r--. 1 perex perex 172032 Jul 24 15:44 sof-cnl.ri -rw-rw-r--. 1 perex perex 278528 Jul 24 15:44 sof-icl-signed-intel.ri -rw-r--r--. 1 perex perex 172032 Jul 24 15:44 sof-icl.ri
Is that ok?
The firmware used for production is typically built with the Cadence tools, which unfortunately are not available publicly (but can be made available to Intel partners). It wouldn't be surprising if the code size was different due to the use of intrinsics (though 100K seems like a lot indeed).
Liam, I think we ought to release binaries with the community key as well so that people can use them as is, e.g. on the Up2 board which does not require the Intel production key. Same for GLK Chromebooks.
It would be probably more nice to create a tar ball with all firmware and topology files bundled with the proper (usual) filesystem location (/lib/firmware/intel/sof/... and /lib/firmware/intel/sof-tplg/...). So we (users/distribution packagers) can just use it.
BTW: Do we need UCM config files for SOF, too?
