Confusion about flashing to a USB Drive

Hello, I have a question. Are you running these operations on the HOST or on Jetson TX2?This is a silly question, but please help me,I didn’t understand the User Guide.

I have not set up for a USB drive. However, in general the software performing a flash runs on a host PC. When in recovery mode the Jetson becomes a custom USB device, and the “driver package” (which JetPack/SDK Manager is a front end to) understands the custom device. Anything referring to “” (and more) is something running on the host PC for flashing to a Jetson in recovery mode (later on in the process of flashing there might be some optional packages which are installed to a fully booted system, but flashing itself is always to recovery mode Jetsons).

Thank you very much for your help. I will try it on the host computer today.(≧∇≦)ノ

I have solved this problem.The method is here.
