No video on Toradex Apalis IMX8

pgiangrossi · September 1, 2021, 4:14pm

I am using Yocto with the 5.2.0 Toradex Manifest and mender layers for OTA support. I am building the tdx-reference-multimedia-image, and I get no video output. I have tried HDMI, and LVDS, but same results.

My board is an Apalis IMX8 QM V1.1C with an ixora 1.2 carrier board.

When I run the tdx-reference-multimedia-image from the Toradex JFrog repository, I get video output. The only difference I can think of is that I have added the mender layers.

Is it possible that the mender layers are causing the video to not work? I know this is a stretch, but I have been at this for a week with no progress.

I noticed one error when using mender that does not show in the working image:

1.669447] imx-drm display-subsystem: parent device of /bus@57240000/ldb@572410e0/lvds-channel@0 is not available

And weston@root.service is failing with:

Some debugging reveals that there is no /dev/fb0 present:

fbset: can't open '/dev/fb0': No such file or directory

None of these errors is seen with the tdx-reference-multimedia image retrieved from toradex’s jfrog artifactory.

Hi @pgiangrossi the first step would be to dump the kernel command line parameters in both images to make sure the Mender one has all the same bits. I tried to make sure they were identical since Mender does modify the bootcmd, but it’s possible I missed something.

Drew

pgiangrossi · September 1, 2021, 4:48pm

Hi Drew, here is the working command line:

root@apalis-imx8:~# cat /proc/cmdline 
pci=nomsi root=PARTUUID=23f58d39-02 ro rootwait

The non-working one (mender) looks like:

root@apalis-imx8:~# cat /proc/cmdline 
pci=nomsi root=/dev/mmcblk0p3 ro rootwait

I see some changes to boot.scr. The mender version took out some overlay support.

Paul

drewmoseley · September 1, 2021, 5:09pm

OK. I suspect it is the overlay stuff that is missing. You can probably re-add equivalent functionality with MENDER_UBOOT_PRE_SETUP_COMMANDS or MENDER_UBOOT_POST_SETUP_COMMANDS or by modifying the boot.scr based on the MACHINE type. If you have a chance to prototype something that would be helpful.

The following patch on meta-mender-community gives me video output on the mender version of tdx-reference-minimal-image.

I’ve tested the script stand-alone. Testing the yocto-generated image now…

drewmoseley · September 2, 2021, 2:47pm

I’m surprised you need this. I thought those were added automatically.

Drew

pgiangrossi · September 2, 2021, 2:50pm

you’re probably right, I’ll check

pgiangrossi · September 2, 2021, 3:53pm

So the build does not appear to be correct. I am getting a file boot.scr-apalis-imx8 in the deploy/images/apalis-imx8 folder. That file is what I want. But when I deploy, /uboot/boot.scr is not correct. It looks like what was there before deploying.

Am I missing something?

drewmoseley · September 2, 2021, 4:13pm

You may just need to wipe the tmp/ dir and build again. But the real culprit is likely some other package providing the boot.scr file. I just don’t know which one.

Drew

pgiangrossi · September 3, 2021, 2:08pm

You were right, I had to delete some history and re-build mostly from scratch.

I also made the change you suggested earlier. I tested this by programming the yocto-generated image in recovery mode. So I can say that this patch is tested from my side. Here’s the updated patch:

Can you submit that as a pull request here?

Drew

pgiangrossi · September 3, 2021, 3:06pm

The pull request above works for the HDMI output. On my local build, I want to make it work for the Toradex LVDS 10.1" screen, so I add the following to local.conf:

TEZI_EXTERNAL_KERNEL_DEVICETREE_BOOT = "apalis-imx8_lvds_overlay.dtbo apalis-imx8_atmel-mxt_overlay.dtbo display-lt170410_overlay.dtbo"

But it doesn’t have the desired effect. How do I do this correctly?

pgiangrossi · September 3, 2021, 3:53pm

Seems like I have to remove and append to get that to work.

TEZI_EXTERNAL_KERNEL_DEVICETREE_BOOT_remove = "apalis-imx8_hdmi_overlay.dtbo"
TEZI_EXTERNAL_KERNEL_DEVICETREE_BOOT_append = " apalis-imx8_lvds_overlay.dtbo apalis-imx8_atmel-mxt_overlay.dtbo display-lt170410_overlay.dtbo"

drewmoseley · September 3, 2021, 6:09pm

Yeah, that doesn’t surprise me. I’ll continue the discussion over in the PR.

Hi Drew, I just noticed that with the pull request, I cannot do a mender update. Any idea what these errors might indicate?

That generally means that something is unhappy in the U-Boot environment. It could be that the u-boot-fw-utils config file is incorrect.
