change dtb file using file copy(scp) not use flash.sh

Autonomous Machines Jetson & Embedded Systems Jetson TX2

I followed “Jetson_X2_Developer_Kit_User_Guide.pdf” and flash binaries using jetpack.
After then, I tried to change dtb file using file copy(scp) not flash.sh.
I refered below link for this and modified extlinux.conf
Jetson/TX2 DTB - eLinux.org // Add FDT /boot/tegra186-quill-p3310-1000-c03-00-base.dtb

but after this, board has not boot up with below error message.
Do I need more fix for it?

Unless you are using an older version of L4T you cannot use the FDT entry in extlinux.conf. The specifics vary by which release of L4T. Which version are you using?

The newer versions merge some of their boot environment into the device tree, and the device tree itself is in a partition. The flash tool may do some editing or adjustments before placing the tree into the partition.

I’m using JetPack-L4T-3.2-linux-x64_b196.run
So, Do I have to update kernel image(Image) using file copy(scp) and update dtb to partition using flash tool seperatly?

That is correct. I know it isn’t convenient, but if you look at the list of partitions (using “sudo gdisk -l”) it looks like there is some work going on to actually ease in-place updates (I’m only speculating…but if that is the case, then the pain of the current setup will some day become easier instead of worse).

Okay, I understand.
Thank you for your answer.
