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
There are two USB ports on the carrier card and three Ethernet interfaces (one connected to a PS GEM and a pair connected to the PL-based Ethernet controllers). As shown in the following figure, Ethernet 0 (PS) on J24 is the default firmware and software Ethernet interface used for the image recovery application and the primary Ethernet interface in Linux.
