On Xavier NX, what command should I use to flash the device tree?

[liuyuhangpro]

When I use the command ‘sudo ./flash -r -k kernel-dtb jetson-xavier-nx mmcblk0p1’ to flash the device tree, I get the following error:

Hi,

To update the device tree, please just overwrite the file specified in /boot/extlinux/extlinux.conf.
They are by default read from the rootfs, so even if you update the kernel-dtb partition, it’s not going to take effect.

Take AGX Xavier for example:

LABEL primary
      MENU LABEL primary kernel
      LINUX /boot/Image
      FDT /boot/dtb/kernel_tegra194-p2888-0001-p2822-0000.dtb
      INITRD /boot/initrd
      APPEND ${cbootargs}
