Dear；

In https://github.com/nxp-imx/linux-imx/blob/lf-6.1.y/arch/arm64/boot/dts/freescale/imx8mp.dtsi, currently iMX8MP support multiple screen display. But now I need MIPI-DSI output an image screen, while HDMI output the same content, May I ask: IMX8MP can achieve multi-screen display? If so, how to configure it?

Thank you!

Best Reards!

Hi @jack_huang1,

Thank you for contacting NXP Support.

Yes, the i.MX8MP can achieve multi-screen display.
Regarding hardware, you can use the imx8mp-evk-rm67191 that enables output of MIPI-DSI for that display model.
For software, the BSP doesn't support clone screens. In this cases, you will need to work in weston.

I hope this information will be helpful.

Have a great day!
