Hi,

 

We are working on iMX8QM custom board (B0 CPU) with 4.14.98 Kernel BSP.
The DP(Display Port) interface is crashing while booting.

 

We tested the same with iMX8QM ARM2 LPDDR4 CPU Validation Board, in that also facing same issue.
We used below DTS file as reference for DP support.

arch/arm64/boot/dts/freescale/fsl-imx8qm-lpddr4-arm2-dp.dts

The boot log is attached for your reference.

 

Kindly support us to resolve above issue as soon as possible.

 

Best Regards,

Prashanth Kumar K
