Nvidia Jetson Nano Device Tree ADV7282M

Hello

I’m trying to get an ADV7282M Board up and running with the Nvidia Jetson Nano.

I took the device tree from ADV7280m configuration - #105 by hoanganhv1svm and copied it to Linux_for_Tegra/source/public/hardware/nvidia/platform/t210/porg/kernel-dts/porg-platforms/tegra210-camera-rbpcv2-dual-adv7280m.dtsi.

Then I removed #include "porg-platforms/tegra210-porg-camera-rbpcv3-dual-imx477.dtsi" and
#include "porg-platforms/tegra210-porg-camera-rbpcv2-dual-imx219.dtsi and added #include "porg-platforms/tegra210-camera-rbpcv2-dual-adv7280m.dtsi" in the file platform/t210/porg/kernel-dts/tegra210-p3448-0000-p3449-0000-b00.dts

I rebuilt the kernel and updated the dtb on the Jetson Nano. For that I added FDT /boot/tegra210-p3448-0000-p3449-0000-b00.dtb in extlinux.conf.

When booting it loads the correct dtb:

[    0.207621] DTS File Name: /run/media/user/d8879b5a-fbbc-4f2f-8661-0fe055396189/nv/Linux_for_Tegra/source/public/kernel/kernel-4.9/arch/arm64/boot/dts/../../../../../../hardware/nvidia/platform/t210/porg/kernel-dts/tegra210-p3448-0000-p3449-0000-b00.dts
[    0.207629] DTB Build time: Jan 25 2022 10:57:57

But I don’t see any adv7180 driver messages in dmesg. Is there something wrong?

root@linux:~# dmesg | grep adv
root@linux:~# 

Sorry for the late response, is this still an issue to support? Thanks

hello user150318,

had you configure the kernel driver to enable the config?
please also refer to this training video for the sensor bring-up, V4L2 Sensor Driver Development Tutorial
thanks
