Hi @DylanMingan
You can follow the steps below to edit and update the dts.
- Convert dtb to dts source file
$ dtc -I dtb -O dts /boot/dtb.img -o new-dts.dts
new-dts.dts is current dts source file.
- Modify dts you want
$ vim new-dts.dts
...
- Convert dts to new dtb
$ dtc -I dts -O dtb new-dts.dts -o new-dts.dtb
new-dts.dtb is the new dtb.
- Backup old dtb
$ sudo cp /boot/dtb.img /boot/dtb.img.backup
- Update to new dtb
$ sudo cp new-dts.dtb /boot/dtb.img
$ sync
- Reboot to use new dtb
$ sudo reboot
