Questions for secureboot and trusty

I want to enable secureboot and trusty, program all fuses in single step really with:
“sudo ./odmfuse.sh -j -i 0x19 -c PKC -p -k rsa_pri.pem --KEK2 KEK2.txt -S SBK.txt jetson-xavier-nx-devkit” accroding to the reference: “Welcome — Jetson Linux<br/>Developer Guide 34.1 documentation”,
but I failed.
so I changed command line parameter, may be “sudo ./odmfuse.sh -j -i 0x19 -c PKC -p -k rsa_pri.pem --KEK2 KEK2.txt -S SBK.txt jetson-xavier-nx-devkit”, may be “sudo ./odmfuse.sh -j -i 0x19 -c PKC -p -k rsa_pri.pem --KEK2 KEK2.txt jetson-xavier-nx-devkit”, and one of them worked.

This causes odm_production_mode to be set to 1, so I can’t burn fuses others now. Is there any way to set odm_product_mode to zero.

I’m a beginner. I don’t understand a lot of it. Can you read it?

I tried your solution at “Unable to burn fuses (dev kit) / no more output (serial/hdmi) / bricked? - #89 by DaneLLL”, but when i do “sudo ./fusecmd.sh”, I got “Error: Return value 3”
