Device tree doesn't flash on tx2

Hello All,

I was developed custom camera device driver.

I’m was upgrade sdkmager1.4.0.7363 ( jetPack 4.5 from 4.4.1 )
I was install jetPack4.5 on Jetson Tx2.

and then i added device tree files (dtb) for custom device.

  1. device tree compile
  2. copy to Linux_for_Tegra/kernel/dtb
  3. run flash.sh in Linux_for_Tegra folder

I flashed dtb files using flash.sh as shown below.
sudo ./flash.sh -r -k kernel-dtb jetson-tx2 mmcblk0p1

flash fusing was abnormal progress as shown below.

jpchae@ubuntu:~/Linux_for_Tegra$ sudo ./flash.sh -r -k kernel-dtb jetson-tx2 mmcblk0p1

Reusing existing system.img... 
file does not exist.

what do i need for flashing for device tree?

hello jpchae,

according to below.

$ sudo ./flash.sh -r -k kernel-dtb jetson-tx2 mmcblk0p1

Reusing existing system.img... 
file does not exist.

had you generate system image before?
you’re using -r options, which skips building system.img and reuse the existing one.
you may exclude it for testing,
thanks

Hello JerryChang,

Thank for your help.

as your comment, i removed “-r” option , and then dtb file was flashed.

thanks,
