i am developing xavier nx commerial module p3668-0001 based on Jetpack 5.0.2,
compile kernel dts and copy all generated dtb files into kernel/dtb folder,
then flash dtb by following command:
sudo ./flash.sh -r -k kernel-dtb jetson-xavier-nx-devkit-emmc mmcblk0p1
then reboot device and check the booting log,
it sees dtb no changed…
FDT entry, the device tree is loaded via file system.
FDT in the
/boot/extlinux/extlinux.conf, then it’ll load via kernel-dtb partition.
if i want to update dtb by flash tool,
first, remove /boot/extlinux/extlinux.conf, then flash on PC;
if i want to update dtb without flash tool,
replace kernel_tegra194-p3668-0001-p3509-0000.dtb located in /boot/dtb by new one, then reboot.
Is it right?
yes, your understanding is correct.
