Hi all,

I am following this guide here to allow my Orin board to enter lock mode:

This was for “Jetpack 5.0.1” but when trying to use the same changes for 5.0.2 or 5.1.0 it will not boot. Is there a different way to allow lock mode in new versions of Jetpack?

please refer to public documentation, you may check CPU Split-Lock Feature section for the steps.

I have followed these steps with Jetpack 5.1 and met with no serial output & a black screen. Has there been a change from 5.0.1 to 5.1 which would affect this?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
