I've encountered an power supply issue with microZed Soc. I'm trying to power the board using USB charger/Battery back. It worked fine through the UART USB port. But if I connect it through the DC barrel jack or VIN_HDR on the expansion header, the boot process will end up in a reset loop. Caps 212 217 218 are depopulated.
The reset happens after PL configuration and before entry to the OS. The multimeter show a significant voltage drop at the precise moment.
I've checked the schematics of the board design (rev F). Power through UART and VIN_HDR is no different. I've also included a polyzen on my carrier card.
Can someone shed some light on this?
