Hi everyone:
The hardware platform is TX1 and filesystem is L4t R28.1. In uboot i tftp Image and dtb to corresponding address and i use booti to boot the kernel with dtb.Everything seems fine. When i use onboard camera i can’t fine /dev/video0.So i burn the same kernel and dtb to mmc the /dev/video0 comes out and the camera works ok.So i check the bootlog,there is the problem:

I don’t know the reason.

Due to plugin manager support bootloader need to modify the DTB base on the child board’s EEPROM to enable the correct driver. The booti may not use the modified DTB cause the problem.

Thanks for the replay.
Then what should i do to use booti.

What reasons/purpose you must need booti?

Thanks for the reply.
I want to debug kernel driver and the dtb.Using usb otg to debug dtb and driver is not convenient.So i use tftp to download the kernel and dtb and use nfs to debug fs.

@wjljy1
That’s interesting. Could you explain more about the tftp and nfs to debug fs that would help figure out a solution.

Thanks for the reply.
I delete the plugin-manager support on camera.The problem is solved.
