I’m using AGX Dev Kit with JetPack 4.5.2 and I try to find a way to replace the device tree. One way is to flash the whole system but I try to avoid this way.
The other way is to flash the devicetree only. In the past this has been successfully done with Jetson TX1:
$ sudo ./flash.sh -r -k DTB jetson-tx1 mmcblk0p1
$ sudo ./flash.sh -r -k DTB -d <device tree> jetson-tx1 mmcblk0p1
So I adapted this call for the AGX Dev Kit like
$ sudo ./flash.sh -r -k DTB jetson-agx mmcblk0p1
but unfortunately I get
Error: Return value 13 Command tegradevflash_v2 --write DTB 1_kernel_tegra194-p2888-0001-p2822-0000_sigheader.dtb.encrypt Failed to flash/read t186ref.
What is the correct way to put a new devicetree on the AGX Dev Kit (without flashing the whole system)?
Thanks in advanced.
