Hello, I’m trying to work out whether the Jetson Nano supports encryption of the boot loader (U-Boot), and if so how one would go about it. The Jetson Nano Fuse Specification Application Note hints at the possibility with the SBK + DK, but then also goes on to state that this is obsolete and not us…

Hi, and thank you for your answer. Could please confirm that once the ODM Production Mode fuse has been blown, it would not be possible to read out the ODM Reserved fuses externally? The application note is not entirely clear on this aspect, and suggests it only applies to the production fuses, not …
