Xavier NX device tree sets xavier-nx-devkit-emmc into a boot loop

[vK-embedded]

tegra194-p2888-as-p3668-p2822-0000.dts/dtb is been declared as the Xavier for Xavier-nx devkit model

Jetpack 4.6

Simply replacing the device tree by adding FDT in /boot/extlinux/extlinux.conf seems to be putting into a boot loop with the Nvidia logo being shown again and again.

The reason I need is to access the ov5693 in the device tree which the stock device tree doesn’t have : tegra194-p3668-all-p3509-0000.dts/dtb

How do I make it work?

Thanks,

I don’t see a reason to use this dtb. This is more like some old emulation dtb before NX getting released…

Alright. What would your suggestion be to get OV5693 working in tegra194-p3668-all-p3509-0000.dts/dtb @ Xavier-NX

unlike nano, xavier-nx seems to support the ov5693 sensor in the official documentation. But going through the dtsi files in t19x/jakku/ I haven’t found anything relevant.

Follow below link to download the kernel source from download center.
Then integrate the ov5693 device tree to tegra194-p3668-all-p3509-0000.dts

How do I integrate ov5693 to tegra194-p3668-all-p3509-0000.dts for tegra-l4t-r32.6.1.

From what I understand. ov5693 is shown in the device tree source includes for galen ie Xavier agx
but not for jakku ie Xavier nx

both at {Source}/hardware/nvidia/platform/t19x/

I could be wrong, but that’s what i’m trying to figure out

Do let me know if my question isn’t clear.

You need to include the device tree of ov5693 or maybe need copy and modify it for XNX.
