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.
