Can I update the DTB using the network?

we can use copy the Image to /boot for updating the kernel;
Is there a similar method to update the tegra194-p2888-0001-p2822-0000.dtb through the network

You need to configure FDT field in extlinux.conf so that it will read dtb from rootfs instead of partition.

Sorry, I’m not sure where this should be modified.
Can you give me some suggestion, Thank you very much.

I find the file : extlinux/extlinux.conf
but I donot kown how the modify it .

Is it just need to add this?

FDT /boot/tegra194-p2888-0001-p2822-0000.dtb

Add it, reboot and check your uart log.

Thank you, that is OK
