hello zhihui.zhu,
the BOOT_SECURITY_INFO was burned (by manufacturing) to 0x1E0 as default value.
it’s also as mentioned by Jetson Orin Fuse Specification v1.5.
let me re-cap as below..
FUSE_BOOT_SECURITY_INFO_0
- Bits [8:4] Reserved (may not be logic 0 by default)
please update your fuse configuration file, especially the BootSecurityInfo.
for instance, please fuse devices with a BootSecurityInfo value by doing an OR with 0x1E0.
