Hi Guys, I am having some strange things going on with voltage levels and voltage drop.
First I noticed issues when powered from my MacPro, If I loaded the cpu then the board could reboot, it could also get in a state where it needed multiple reboots to get started. So I connected up to a 2.5A USB supply and this issue goes away. Another issue I am seeing though is I am only getting 4.6V on SYS_5V. I have connected a BBB to the same supply and see 5V on SYS_5V. Also under cpu load SYS_5V drops to 4.3V. When powered from the MacPro SYS_5V is 4.3V and drops to 4V under load and reboots. I tested a BBB connected to the MacPro and only get 4.7V on SYS_5V. Also when connected to the power supply VDD_5V is only 2.16V. Has anyone got any idea what might be going on here?
