Hi,
I’m trying to build my own TorizonCore image with a modified device tree.
I’m using a Apalis imx8qm on a apalis evaluation board. I’ve added this part to my tcbuild.yml file:
customization:
device-tree:
include-dirs:
- device-trees/include/
custom: device-trees/dts-arm64/imx8qm-apalis-eval.dts
Before I enabled the customization part the image build fine and I could run it on my board. But when I added this part I got some troubles.
I can build the image and I can install it on my module using the Toradex Easy Installer, but when I reboot the device I can’t get an ssh connection anymore.
I haven’t made any other changes, just added these lines but they should work right?
My idea was to replace the dtsi files in the device-trees/dts-arm64 folder with my customized files and build an image, but I can’t even make the image work with the defualt files.
Best regards,
Pontus
Hi @pontusoim,
How are you? Could you please share with us more information on the topic?
- Which Apalis version are you using?
- Which TorizonCore version are you trying to build?
- Which TorizonCore Builder version are you using?
Also, could you please share with us your full tcbuild.yml and the device tree files you’re using? You could use share.toradex.com to do so and send the link here or by a private message if you feel more comfortable.
Best regards,
Hi,
I’m using the Apalis iMX8QM 4GB WB IT V1.1 C
I’m using the torizon-core-docker-apalis-imx8-Tezi_5.6.0+build.13.tar image
And I’m using torizoncore-builder 3.5.1
My tcbuild.yml looks like this:
input:
easy-installer:
local: torizon-core-docker-apalis-imx8-Tezi_5.6.0+build.13.tar
customization:
device-tree:
include-dirs:
- device-trees/include/
custom: device-trees/dts-arm64/imx8qm-apalis-v1.1-eval.dts
output:
local: my_image
name: "My customized image"
bundle:
dir: bundle/
I got it to run now but I still have a problem. My docker compose file starts two containers, one is the Weston container that I just copied from the docker-compose file you get when you build the image with evaluation containers, and another container that runs my application. When it starts the weston container exits straight after it starts, so I can’t see anything on my connected screen. I have only added the custom: device-trees/dts-arm64/imx8qm-apalis-v1.1-eval.dts line, I haven’t changed any dtsi files or anything like that. If I remove that line from the tcbuild file the weston container runs fine.
Can you help me to figure out why that device tree kills my weston container?
This is the log from the weston container after it exits:

Hopefully it can give some clues to why it exits.

Dear @pontusoim,
It seems that the drm device was not found. Could you please share with us the changes that you made to your device tree? You could use share.toradex.com. Also, are you using which kind of screen?
Have you enabled the proper overlays? Setting up Displays with Torizon | Toradex Developer Center
