Hi,
We are trying to use both displays with imx8qm and ixora.
Tested with unmodified image from a link from toradex developer page image used: b2qt 6.4.3
from
Qt for Device Creation (Boot to Qt) | Toradex Developer Center
https://docs.toradex.com/106697-b2qt-embedded-qt5-image-apalis-imx8-tezi.tar?v=14
default settings for the display is HDMI and settings are following:
overlays.txt file:
fdt_overlays=apalis-imx8_hdmi_overlay.dtbo apalis-imx8_spi1_spidev_overlay.dtbo apalis-imx8_spi2_spidev_overlay.dtbo
kms.conf file:
{
"hwcursor": false,
"device": "/dev/dri/card1"
}
with these default settings HDMI works.
Then, we want to change it to use a touch screen :
overlays.txt file:
fdt_overlays=fdt_overlays=apalis-imx8_panel-lvds-dual-channel-1080p_overlay.dtbo
kms.conf file:
{
"hwcursor": false,
"device": "/dev/dri/card1",
"outputs":
[
{ "name":"LVDS-1", "mode":"1280x800", "virtualIndex":0 }
]
}
with these settings touch screen works.
But we want to use both screens.
When we change the settings on both files, kernel crashes on startup with different error on each time.
overlays.txt file:
fdt_overlays=fdt_overlays=apalis-imx8_panel-lvds-dual-channel-1080p_overlay.dtbo apalis-imx8_hdmi_overlay.dtbo apalis-imx8_spi1_spidev_overlay.dtbo apalis-imx8_spi2_spidev_overlay.dtbo
kms.conf file:
{
"hwcursor": false,
"device": "/dev/dri/card1"
"outputs":
[
{ "name":"LVDS-1", "mode":"1280x800", "virtualIndex":0 },
{ "name":"HDMI-A-1", "mode":"1920x1080" }
]
}
Following is the early step of the startup, added as a information:

I see a massive difference on overlay file changes on this release.
On previouse releases boot/overlay/ folder had different dtbo files than this one. Such as, there were no apalis-imx8_spi1_spidev_overlay.dtbo apalis-imx8_spi2_spidev_overlay.dtbo files. Touch screen
overlays dtbo file had a different name.
ls /media/BOOT-mmcblk0p1/overlays/
apalis-imx8_ar0521_overlay.dtbo

Could anyone help me on this. It is the default not-modified b2qt image and I’m still getting this error if I want to use dual screen setup.
Best regards
