Hi nvidia,
im begiiner in nvidia jetosn and use jetson orin nx i learn about this and use diffrent tools
i use secure boot and dont know what happend and my jetson not flash and all .key file is missed.
now i cant use my jetson and re flash again.
i saw the forume nvidia and do not give a good answer for my problem can you help me to reset my jetson i dont have any data in my jetson i just re flash again
You must have the key to sign any newly flashed content. Without the key there is no reversing this (assuming security fuses actually burned; if the burn process failed, then even though you tried to burn security fuses, perhaps a regular flash will work).
The boot stages are designed to not accept incorrectly signed content. Even the default case unburned fuse flashes have this rule…the difference being that without security fuses burned a NULL key is accepted; default flash signs with that NULL key. Are you certain that the fuses were actually burned?
Now if you modified your flash content to use keys thinking the fuses did change, you might need to create an alternate directory with a new/default flash software (be careful to not delete your old content), and try flashing that way and see if it boots. If not, then there is nothing that can be done without the key.
thanks for your answer
I know need .key file but i missed all my key
i want to find any way to find re flash my jetson
i dont have any data in my jetson i just re flash my jetson and can use it again .
If you have the key file, then you should be able to flash it (although the commands for flashing with a key file and a security fuse burned Jetson would differ). It sounded like you had lost the key though.
Maybe @WayneWWW or @KevinFFF can suggest the correct command to flash using the key.
no any way for re flash without rsa.key ?
jetson do not have hardware reset or anything else can help me ?
Even if you do figure out how to flash, all content other than the rootfs partition must be signed by that key. If not signed by that specific key, then the content is rejected. It won’t matter if you can’t flash, versus flashing and having the content rejected. Whatever you need to do to find that key, if there is any possibility, is mandatory. There is no hardware reset for burnt key fuses.
Note: Make sure the fuse burn was actually successful. If there was a failed fuse burn, then perhaps the system still uses default software.
