Kernel Flash fails with dtb missing error

[hc_0302]

I have downloaded L4t 32.6.1 sources for my jetson agx xavier then I tried to build kernel
by refering to the following link:
https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/kernel_custom.html#wwpID0E0WD0HA
After building I got the Compiled kernel in kernel_out directory and then I did following steps on linux host pc:

1. Copy and replace kernel_out/arch/arm64/boot/Image to <release_package>/Linux_for_Tegra/kernel/Image
2. Similarly I deleted all the files inside <release_package>/Linux_for_Tegra/kernel/dtb/
   and then copied all files from kernel_out/arch/arm64/boot/dts/ to <release_package>/Linux_for_Tegra/kernel/dtb/

After doing this we started to flash the jetson with this linux host pc . but got the following error:

Can anyone please support here ?
