Hi all,


We are evaluating the dual display use case in NXP's imx8mq based evk board with your
L4.14.98-GA prebuild image. For dual display use case, we referred Quick Start Guide for IMX-MIPI-HDMI for i.MX 8M Evaluation Kit. We stopped booting process at uboot and setenv fdt_file fsl-imx8mq-evk-dual-display-b3.dtb for dual display then boot the kernel.


We see both displays working fine. but after some time when we hard reboot the system screen on MIPI-DS, I (HDMI2)bridge is shifted on vertically.

I have attached photos for your reference.


We are developing imx8mq based on our custom design and dual display use case is part of our project. So,

Can you please help us to resolve this issue ASAP?

Please let me know if you need further information.
