Which feature do I must enable to use the LVDS0 LCD without it6263 in iMX8QM MEK B/D?

[hyun-moyang]

Hi all,

I am trying to enable the LVDS for LCD without the bridge of it6263 in iMX8QM MEK B/D in android auto platform software that the software version is android-11.0.0_1.1.0-AUTO.

And I'd like to use the Full-HD LCD(1920x1080).

Which feature do I have to enable to use the LVDS0 of LCD without the IT6263 in /vendor/nxp-opensource/kernel_imx?

 Regards

HM

I am afraid it is not supported, so it is necessary to make software changes.

One can start with linux  imx8qm-mek-jdi-wuxga-lvds1-panel.dtsi

https://source.codeaurora.org/external/imx/linux-imx/tree/arch/arm64/boot/dts/freescale/imx8qm-mek-j...

it uses panel-simple.c driver, custom lcd timings can be adjusted in " struct display_timing jdi_tx26d202vm0bwa_timing" :

In general, in Android Automotive default image, M4 will be responsible for displaying
at the starting stage. Therefore a lot of resources is assigned to M4 first, and the dts for
Automotive is a little different.
