How to get firmware-imx for imx8mm evk into sdcard image? I'm getting firmware loading errors for sdma-imx7d.bin etc.


Brian Hutchinson
 

Just built latest Freescale Community BSP core-image-minimal (kernel 5.4.67 was built) for imx8mm-evk and firmware-imx is not included in sdcard image ... which I think is why I'm getting messages like these:

[    0.127623] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2

[    4.013621] imx-sdma 302c0000.dma-controller: external firmware not found, using ROM firmware

I found the firmware files in:

build/tmp/work/aarch64-mx8mm-poky-linux/firmware-imx-8m/8.8-r0/firmware-imx-8.8/firmware

... and copied them to the sdcard under /lib/firmware/imx directory but I still get the firmware errors.

How "should" I be getting these firmware binaries into the core-image-minimal sdcard image to also get rid of the firmware loading errors?

I'm using a rev B imx8mm-evk board and using the imx8mm-evk-revb.dtb.

Regards,

Brian

I'm using core-image-minimal because I have a custom board based off of imx8mm evk but don't use wifi, bluetooth, video, touch pad etc. so I don't want all the "stuff" that comes in core-image-base.  Just background for those that might ask.

Regards,

Brian

Another update ... decided to build core-image-base just in case it was related to core-image-minimal missing something ... I get the same sdma errors.  So I add IMAGE_INSTALL_append = " firmware-imx-sdma-imx7d firmware-imx-epdc" to local.conf.  Still get the errors.

I'm stumped.

I fixed this on master and dunfell; please do a repo sync and give it a new try.

Hi Otavio,

That's great!  Just curious when was this done as I did a fresh repo init/sync of dunfell yesterday afternoon.

repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b dunfell

Regards,

Brian

Excellent!  Thank you!

I got to poking around in one of the include files and looks like I should have done:

MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d'

... instead of:

IMAGE_INSTALL_append = " firmware-imx-sdma-imx7d firmware-imx-epdc"

... in local.conf.  Is one of these still needed or should it key off the fact I'm using a imx8mm evk machine?

Regards,

Brian

So I did build of core-image-minimal with local.conf containing MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d' and still got the sdma errors.

No firmware-imx packages were installed and no /lib/firmware directory created so I guess that explains why.

Now I'm off trying core-image-base.  I'll comment out:

MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d'

... and try that first.

Mush Ryzen 9 3900x, mush!

More background information in case it matters.

I did my original setup with:
EULA=1 MACHINE=imx8mmevk DISTRO=poky source setup-environment build

... because I don't want/need graphics etc.

After Otavio did his change, I smoked sstate and tmp dir and rebuilt core-image-base.  Still get sdma errors and do not have /lib/firmware/imx
/ binaries.

... what "distro" 'should' I be using since I have a custom board that's based on imx8mm evk but I don't necessarily want/need wifi, bluetooth, video, touchscreen etc.???

Is poky what's causing my pain?

I've been doing TI based builds forever and recently switched over to NXP based products so still learning the lay of the land.  I finally discovered I don't think I want to be building based off NXP releases from codeaurora and that Freescale is the better base for our products but not 100% clear what distro's are available and which ones I should focus on.

I suggest you go with your own distro then, as you can leverage the
DISTRO_FEATURES in it yourself. You can either take any of 'fsl-'
prefixed distros over 'poky' if you need some NXP proprietary
components (e.g. VPU, GPU, etc), or take any of 'fslc-' prefixed ones
if you want to stay with mainline. Please note - I do not say that
'poky' would not work here! :) It is just a reference distro from
Yocto Project, which targets qemu on the first place, but also works
well for real HW.

This is the way we build our distro (derived from 'fsl-wayland'), and
so far it has proven to be working quite well. I also do sanity build
and run the 'fsl-wayland' off the master on imx8mmevk to make sure
there are no regressions.

You can see what distro features you have included when you do
'bitbake -e' and search for DISTRO_FEATURES. If you have (and
according to what you say - you do :) ) some pieces you do not need -
you can always either not include them in your custom distro, or use
DISTRO_FEATURES_remove = "<unneeded list>".

Those distros are located in a meta-freescale-distro layer, you can
peek there to see what's available.

Hello Brian,

See if below change fixes it:
That should actually do the trick! I just realized that the mx8m is

Let me try this out on the imx8mmevk, I'll get back on this one.

So I did build of core-image-minimal with local.conf containing MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d' and still got the sdma errors.

No firmware-imx packages were installed and no /lib/firmware directory created so I guess that explains why.

Now I'm off trying core-image-base. I'll comment out:

MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d'

... and try that first.
Brian,
Did you try Otavio's patch? Would be curious to know if that solved
the absence of SDMA FW package for you.

I did a repo sync before building.  Did I need to do something else?

When I did NXP released builds I would use fsl-wayland distro but if memory serves me right a core-image-minimal would not boot.  Only core-image-base images did and they were quite large.

I do need to create my own distro but kind of would like to start from core-image-minimal and build up rather than take something like fsl-wayland and try to figure out what I don't need.  Being new to NXP family this approach "feels" more logical.

Is poky what's causing my pain?

So just finished the above cycle and flashed sdcard.  Think we got somewhere this time!

I get only one instance of sdma error:

... of note here is it didn't say it was using ROM version!!!!

And I have firmware package for sdma now:

... and /lib/firmware/imx/sdma looks like:

root@imx8mmevk:/lib/firmware/imx/sdma# ls
sdma-imx7d.bin

So hopefully this helps with the ALSA issue I was chasing that led me to this sdma issue in the first place!

Thanks guys!  I don't know why core-image-minimal isn't working ... I see there is a
firmware-imx-8m package so maybe I should add it.

Brian

No, 4.5 is the external SDMA firmware version. This looks correct.

Smoking sstate & tmp and trying build again with:


IMAGE_INSTALL_append = " firmware-imx-sdma-imx7d firmware-imx-epdc"

So just finished the above cycle and flashed sdcard. Think we got somewhere this time!

I get only one instance of sdma error:

[ 0.117495] EINJ: ACPI disabled.
[ 0.126332] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2

[ 0.134253] mxs-dma 33000000.dma-controller: initialized
[ 0.135378] Bus freq driver module loaded

... of note here is it didn't say it was using ROM version!!!!

And I have firmware package for sdma now:

root@imx8mmevk:~# rpm -qa | grep -i firmware
linux-firmware-ath10k-license-20200817-r0.noarch
firmware-qca9377-3.0.2-r0.noarch
firmware-imx-epdc-8.8-r0.noarch
linux-firmware-ath10k-20200817-r0.noarch
firmware-imx-sdma-imx7d-8.8-r0.noarch


root@imx8mmevk:/lib/firmware# ls -l

drwxr-xr-x 3 root root 1024 Mar 9 12:34 wlan

... and /lib/firmware/imx/sdma looks like:

root@imx8mmevk:/lib/firmware/imx/sdma# ls
sdma-imx7d.bin

So hopefully this helps with the ALSA issue I was chasing that led me to this sdma issue in the first place!

Thanks guys! I don't know why core-image-minimal isn't working ...
Well, this is I guess an expected behavior. firmware packages are
listed in MACHINE_EXTRA_RRECOMMENDS, which is (according to Yocto
Reference manual, link
https://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#var-MACHINE_EXTRA_RRECOMMENDS)
is only considered when packagegroup-base is installed in the image
and does not affect 'core-image-minimal' or 'core-image-full-cmdline'
images.

That is the reason that even if the package is added in the
imx-base.inc (like Otavio suggested in his patch) - you would not
receive it in core-image-minimal and you would have to install it
explicitly.

As for firmware packages themselves, I guess it should be changed from
MACHINE_EXTRA_RRECOMMENDS to MACHINE_EXTRA_RDEPENDS in order to bail
out at the build time rather than figure out that they are not present
on the device at boot time. But this is yet a separate point, which
actually would not solve your original issue as you either need an
image recipe which includes packagegroup-base or you have to
explicitly list them in IMAGE_INSTALL.

I see there is a firmware-imx-8m package so maybe I should add it.
This package is actually empty, and only serves as a deploy target to
provide Cadence HDMI FW for imx-boot to build a boot container. Even
if you try to install it - you would not receive any FW files on the
target.

Brian
