iMX8QM MEK Android Automotive OS 10 Dual Chanel LVDS Panel Issue

[cbl]

Hello,

I want to drive dual channel LVDS panel with Android Automotive OS 10(Kernel 5.4).

For this, I write my Android image to eMMC with "-u md -d md" parameters, but I cannot get an image from my panel.

I included "imx8qm-mek-jdi-wuxga-lvds1-panel.dts" file in "imx8qm-mek-car2-md.dts" file as device tree file.

After doing this with Native Android 10(Kernel 5.4.70), I was able to get an image from my LVDS panel.

But with Android Automotive OS 10, I can't get an image from my panel.

Could you please help this issue?

Best regards,
Efecan

Hello,

Do you try the NXP official Version?

Hello @Bio_TICFSL,

Yes, I downloaded and compiled the official Android Q10.0.0_2.2.0_AUTO (Linux 5.4 Kernel) version of NXP.

But unfortunately I can't get a picture from my dual channel LVDS panel.

Using NXP's official Native Android 10 image and wuxga-lvds1-panel device tree, I was able to get an image from my dual channel LVDS panel.

But I can't do this in Android Q10.0.0_2.2.0_AUTO (Linux 5.4 Kernel).

Could you please help this issue?

Best regards,

Efecan

Hello,

Images were taken from LVDS panels with PWM configurations changed in defconfig and device tree.
