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?
