I want to modify my device-tree and test it.
the generated boot image is appended by dtb file, can I generate separate dtb file and update it only?
Or will it be better to generate whole boot-image and flash and reboot ( for dragonboard 845c )

I’ve never used it on 845 but you can certainly use dbootimg tool for that:
The command could be something like:
cat my-custom-dtb | dbootimg /dev/disk/by-partlabel/boot -u dtb
reboot
let me know…
Dbootimg, thanks, I’ll look for its doc
