Found a solution of DTB live update for R28.1 it doesn’t require going thru the flash process from a host. [url] https://devtalk.nvidia.com/default/topic/1019936/jetson-tx1/jetpack-3-1-how-to-select-different-dtbs/[/url] It’s for TX1 though. Not sure if it works for TX2 as well. Could anyone confir…

Hi tmx3, If you want to update the DTB without getting into recovery mode, please refer to the “dd” method in this thread: How to use UART0 as normal uart port on R28.1? - Jetson TX2 - NVIDIA Developer Forums For me, it worked. And it was verified by Arlen0615.

It is sad that we have to use hacks like dd-ing the device tree into the mmcblk0p15 partition. These would stop working the second they add more things in that partition. I really hope nVidia brings back a simpler way to update out the device tree without needing a Ubuntu x86 host machine.

Lack of a simple/quick way to update device tree is indeed a headache. TX2 is such a powerful intelligence supercomputer, and the dev kit has been made into be a complete system. Debug and trial-and-error are routine tasks in the development. Ideally, you’d wish not to hook up another computer and f…

hello tmx3, FYI, please refer to this similar topic that loading the camera module and get it works, [url] https://devtalk.nvidia.com/default/topic/973087/jetson-tx1/error-compiling-ov5693-driver-as-module-on-l4t-24-2/post/5014011/#5014011[/url] we’re looking another ways to update device tree wit…

Just want to resurrect this old topic. I hope Nvidia will put back support for loading device tree from file in the upcoming Jetpack release. -albertr

Hi JerryChang, any updates on alternatives to update the device tree?

hello Benjamin_Caro, we’ll need to flash the DTB partition for updating the device tree on release 28.1 please check this external wiki page for reference: [url] https://elinux.org/Jetson/TX2_DTB[/url] thanks

For 28.2, the update of the dtb as describe in Jetson/TX2 DTB - eLinux.org does not work. I have decompiled the dtb in the tx2 located in /boot/dtb using dtc -I dtb -O dts -o original.dts original.dtb Made changes to the dev name for e3326 and compiled using dtc -I dts -O dtb -o new.dtb new.dts …

Hi JerryChang, having to use the flash.sh tool to update the device tree works but isn’t really a great story for deployment or customization. I own a Tx2 based platform to which we add custom hardware drivers over time. I would like to be able to tell my customers to simply untar a new kernel (wi…

DTB files in “/boot” are not used. Documentation for newer releases gives information on using flash.sh to update device tree (things change depending on release). Example of an update via flash.sh: sudo ./flash.sh -r -k DTB -d <path/to/device tree> mmcblk0p1 jetson-tx2 Selecting kernels at boot t…

Hello all, I managed to be able to use FDT in /boot/extlinux/extlinux.conf simply by using flash.sh of jetpack-3.0 to install binaries from l4t 28.2 :) It is a little bit tricky, as flash.sh configuration is not consistent :) cd ~/jetpack30/64_TX2/Linux_for_Tegra_tx2 LINUX=<my-kernel-image> FDT…

How to update device tree on TX2

Is it possible to write the modified device tree file using the method described here if I sign it using l4t_sign_image.sh? I’m using a TX2 (l4t 32.3.1)
