Hello,
We are using custom board of iMX8QXP-mek
I built an NXP i.MX Release Distro 5.4-zeus imx8qxpc0mek image.
The board boot on SD card without problem.
I have the display on hdmi screen using the IMX-LVDS-HDMI converter.
My goal is to have the display on an LVDS screen directly connected to DSI1/LVDS1 connector.
So I will not use the IMX-LVDS-HDMI converter for DSI1/LVDS1 connector.
I used the dtb which exists by default to manage the display via lvds (imx8qxp-mek-jdi-wuxga-lvds1-panel.dtb)
=> setenv fdt_file imx8qxp-mek-jdi-wuxga-lvds1-panel.dtb
=> saveenv
=> boot
After booting, I encountered a problem:
The image is blocked at init.

Herewith the full traces.
Are there any explanations?
Is this the correct dtb that I should be using to have the display on the lvds screen?
Thanks & Regards,
