How do I update the kernel and device tree?

We used AGX Xavier industrial Module for visual identification, designed our own baseboard, now using Jetpack4.6.
We are now experiencing a kernel and device tree update failure.
The previous command to update the kernel and device tree is as follows:
sudo ./ -k kernel jetson-xavier mmcblk0p1
sudo ./ -k kernel-dtb jetson-xavier mmcblk0p1
But none of the updates were successful with Jetpack4.6
Please help to provide the latest method of updating kernel and device tree, thank you


you’re having correct commands to update kernel (-k kernel) and device tree (-k kernel-dtb).
when you said failure, does it mean you have complete the flash process but the changes did not applied?
if yes, please check /boot/extlinux/extlinux.conf to see if you’re having LINUX and FDT entry included.

for your reference,
it’s CBoot functionality includes a default booting scan sequence, it’ll have higher priority to load binaries via root file system if the entry specified.

the name of the board is different for the industrial module. Its jetson-agx-xavier-industrial
