hello dcapers44,
you may programming production mode fuse (i.e. -p
option), when PKC and SBK is fused for Jetson Xavier.
there’s a discussion thread about Xavier not booting after burning fuse,
please check Unable to burn fuses (dev kit) / no more output (serial/hdmi) / bricked? - #89 by DaneLLL, as see-also.
thanks
