Dear all:
1: I change Linux_for_Tegra/kernel/dtb/tegra194-p3668-all-p3509-0000.dtb
2: then flash JetPack5.0.1 to JETSON XAVIER NX with our custom board

sudo ./flash.sh p3509-0000+p3668-0001-qspi-emmc mmcblk0p1

3: But after the device poweron, I found that /boot/dtb/kernel_tegra194-p3668-0001-p3509-0000.dtb have no change.

So, how to update dtb file in JetPack5.0.1? In JetPack4.6, it works. thanks very much!

DTB by default read from rootfs. Check your extlinux.conf.

Could I do like that : comment out related line

And, why are you doing like this (add line which not in the previous version) ?

Yes, you can do that.

This kind of configuration can work in previous release too. Nothing special.
