The following figure and table provide an overview of the physical connections, their designators, and relative position on the starter kit. The table uses the following abbreviations to indicate if a specific designator is located on the carrier card or on the SOM.

  • CC = Device or interface is located on the carrier card
  • SOM = Device or interface is located on the SOM

On the carrier card, there are four USB ports. USB0 and USB1 are each connected to a pair or USB physical port interfaces. There are four Ethernet interfaces with one pair connected to PS GEMs and one pair to PL-based Ethernet controllers. As shown in the following figure, Ethernet 1 (PS) on J10C is the default firmware and software Ethernet interface used for the image recovery application and the primary Ethernet interface in Linux.

Location Name Description
SOM DS34 PS done LED Lit indicates that the PS has successfully loaded a PL design.
SOM DS35 Heartbeat LED Periodic flashing green LED driven by the Zynq UltraScale+ MPSoC APU processor.
SOM DS36 PS status LED Status LED, when lit indicates a successful application load.
CC DS1-DS6 Power status LEDs Indicates various power supply and power domain status. Green LED indicates good status.
CC J2, J18, J19, J20 Pmod Digilent Pmod 2x6 expansion header
CC J1 Watchdog out selector J1 is used to select the external watchdog circuit. The default (pin 1-2) routes the output of the watchdog to the PMU GPI on MIO26. In the other position (pin 2-3) routes to the SRST pin of the Zynq UltraScale+ MPSoC.
