Hello,

we are trying to bring up QT application on our custom board with i.MX8MP. Our distro is fsl-imx-wayland. We are getting the following logs when we try to run the application.

weston@imx8mp-lpddr4-evk:~$ ls -la total 824 drwxr-xr-x 2 root root 4096 Mar 9 2018 . drwxr-xr-x 4 root root 4096 Mar 9 2018 .. -rwxr-xr-x 1 weston weston 829808 Mar 9 2018 DASHBOARD_V2 -rwxr-xr-x 1 weston root 150 Mar 9 2018 cluster.sh weston@imx8mp-lpddr4-evk:~$ ./cluster.sh QML debugging is enabled.

Is there any user manual on bringing up QT applications on i.MX boards. What is the issue on our case?

Thanks!

Best Regards.

Hi @Wobaffet

Can you share kms.json ?

Maybe you are using wrong dri node, need to use card1 device.

{ "device": "/dev/dri/card1", "hwcursor": false, "outputs": [ { "name": "HDMI1", "mode": "1920x1080" } ] }

Best Regards
