eMMC partition locking

Is it possible to hardware lock specific partitions of the eMMC on the SOM? We have concerns about potentially corrupting or erasing critical partitions that would brick our system. A hardware lock / unlock sequence would alleviate our concerns.

Our current approach to is make logical partitions read-only (ie. software locking.) However, we’re not completely confident that this is going to be sufficient.


hello tscott-jdes,

you could enable the Secureboot to prevent unauthorized process.
please also refer to Security chapter to enable Secureboot, which prevents execution of unauthorized boot codes through chain of trust.
you should also check access Jetson AGX Xavier Fuse Specification App Note for preparing the board to burn fuses.
