I'm working on direct power CM5/CM5IO with power in J8 +5V but USB-C PSU, according to CM5IO document chapter 2.2 PSU input. However, board boot up with red led, green led and then stop unexpectedly. I then plug USB-A to USB-C cable ONLY and issue keeps the same. JUST after I plug USB-A to the power adapter, even without plug power adapter to power source, board keep boot up and works correctly!
I think the issue comes from cc1/cc2. CM5 need a correct cc1/cc2 setting to keep booting. What I think is add cc1/cc2 Rp to +5V(cheat CM5 the USB-C is plugged) so that CM5 recognize a +5V power is in and keep booting.
Any experience or suggestion is welcome.
