hello mowa,

please note that, NS mode does NOT accept key files.
may I know had your done Xavier fusing before?
you should consider to enable “-p” options as your final step; fuse access will block once odm production mode burned.
you may also refer to Signing and Flashing Boot Files for the procedures to sign and flash boot files.

【Resolved】Finally Successful burn fuses on xavier and the experience share, thanks
