Dual display on iMX8MQ EVK board

Release: Yocto-Sumo (4.14.78_1.0.0_GA)

Board: i.MX8MQ EVK


I want to use the dual-display on i.MX8MQ EVK board and I have NXP OLED display which is used "fsl-imx8mq-evk-lcdif-rm67191.dts" or "fsl-imx8mq-evk-dcss-rm67191.dts" dts files.

I have created new dual display dts file using "fsl-imx8mq-evk-lcdif-rm67191.dts" file.


When I test the newly created dts file only HDMI display works and nothing appeared on NXP display on the mipi-dsi interface.

I have attached board boot-up logs and dts file which I have used for reference.


Does anyone have an idea why it's not working? or I have missed any configuration for that?


Thanks & regards,
