Hi,

What JetPack/L4T version are you using?
Any booting log to provide?

That’s because bootloader by default reads kernel-dtb from rootfs as specified in extlinux.conf, and the kernel-dtb partition is not used unless there is no FDT entry specified in extlinux.conf.

I using Tx2_nx dev kit board
the version is 32.5.1

the log was updated on the post as a txt file attachment

Yes , but the dtb is the same for both in the rootfs and in the emmc

6

Are you using the latest release?

Maybe not, I down load it several month ago. Using Jetpack 32.5.1 all the way

Then please upgrade to the latest L4T 32.7.4.
