Dear Graham,
Thanks for your reply! Yes, I am aware of power-on reset ICs, as well
as simple power-on reset circuits with discrete components. I was hoping
that the designers of the BeagleBone Blue, or experts on the OSD3358, might
be aware solution that was already designed into the system (cut a trace,
short an input, burn a fuse, etc).
Thanks and Best Regards,
-Louis
