Its giving following issue:

Complete log file is attached:

Sorry for the late response, have you managed to get issue resolved?
Any result can be shared?

What do you put inside the usb drive?

I add rootfs to my USB drive.

I also tried the instructions on: Jetson/L4T/Boot From External Device - eLinux.org

But those also give the similar issue.

Hi,

Please note that when you follow the page: Jetson/L4T/Boot From External Device - eLinux.org, you don’t need to check the usb boot error in cboot log because this method still boots the kernel from emmc.
Only the rootfs is booting from usb. If you don’t know what I am talking about, please just ask.
