Orin Nano+DevLit+Jetson Linux 36.4
I modify source/hardware/nvidia/t23x/nv-public/overlay/tegra234-camera-rbpcv2-imx219.dtsi
“make dtbs” to get
./source/kernel-devicetree/generic-dts/dtbs/tegra234-p3768-0000+p3767-0000-dynamic.dtbo
How do I update tegra234-p3768-0000+p3767-0000-dynamic.dtbo only ? flash.sh the whole system takes lot of time.

Hi 627263202,

Please refer to DTB Support to know how we load DTB in Jetpack 6.1(r36.4.0).
It uses DTB from UEFI-DTB by default.

For you use case, please confirm both FDT and OVERLAYS entry have been specified in extlinux.conf on your board. Your custom overlay DTBO would be loaded during boot up if you’ve configured them corretly.
