installation process of dtb #1

well , I tried it just now . but I have some queries on L4t 28.1 ,I didn't understand the installation process clearly .

  1. should i need to compile the kernel ? or should i just need to compile the dtbs doing only "make dtbs" .

  2. And how do i exactly replace the dtbs from linux-l4t-4.4/kernel/kernel-4.4/arch/arm64/boot/dts folder i can see there are total 8 dtb files and among them both tegra210-jetson-tx1-p2597-2180-a01-devkit-hdmi2csi.dtb and tegra210-jetson-tx1-p2597-2180-a01-devkit.dtb exist . but in 64_TX1/Linux_for_Tegra_64_tx1/kernel/dtb folder. I saw 3 dtbs , these three have their counterparts in thelinux-l4t-4.4/kernel/kernel-4.4/arch/arm64/boot/dts folder with the same name too, but sizes are different . so what should be the right way to replace them , replace only the tegra210-jetson-tx1-p2597-2180-a01-devkit-hdmi2csi.dtb or put all of them in the jetpack's dtb folder ? or just remove the tegra210-jetson-tx1-p2597-2180-a01-devkit.dtb file and then paste thetegra210-jetson-tx1-p2597-2180-a01-devkit-hdmi2csi.dtb file ? or should i rename tegra210-jetson-tx1-p2597-2180-a01-devkit-hdmi2csi.dtb file to tegra210-jetson-tx1-p2597-2180-a01-devkit.dtb

  3. should i also replace the Image and zImage and dtc files?

  4. I tried sudo ./flash -r -k DTB jetson-tx1 mmcblk0p1 this command and it says it's looking for tegra210-jetson-tx1-p2597-2180-a01-devkit.dtb but i actually deleted it and placed tegra210-jetson-tx1-p2597-2180-a01-devkit-hdmi2csi.dtb

Please Advise Regards
