Question: Update [kerel-dtb] is not supported, what that means? (Solved)

Try to build kernel, and update dtb.
I can build it, flash kernel into Xavier. But when flash dtb, seems system is not happy.
I used the same method on TX2 before, it works. Any thing changed in Xavier?

gtang@ws4:~/jetpack4/Xavier/Linux_for_Tegra$ sudo ./ -r -k kerel-dtb -d rootfs/boot/tegra194-p2888-0001-p2822-0000.dtb jetson-xavier mmcblk0p1

Hi @gue.tang
You have a typo in your command :
sudo ./ -r -k kerel-dtb
should be:
sudo ./ -r -k kernel-dtb


hello guo.tang,

Spawn32 is correct, you had a typo of your command,
in addition, you may also refer to flash_t194_sdmmc.xml for partition names to have more details.
