hello zc.bj,
let’s try resolve your fuse burning issue.
please refer to Jetson Orin Fuse Specification for the fuse name, i.e. FUSE_BOOT_SECURITY_INFO_0 .
it’s BootSecurityInfo ’s bit [3:0] to indicate the target’s secureboot authentication scheme.
please refer to Jetson Orin Series Modules Fuse Update Field Services Bulletin for the details of FUSE_BOOT_SECURITY_INFO_0 changing to 0x1e0 . you must do bitwise logically OR your desired value with 0x1E0 in the fuse programming flow.
BTW,
you may refer to Topic 359163, let’s try to burn BootSecurityInfo correctly.
