Because the Jacinto7 Common Processor board is used with different SOM boards featuring different Jacinto7
processors with different feature sets, some of the board’s peripherals/interfaces may not be supported. For the
J721E SOM, the following interfaces are not supported:
• USB 3.0 uAB (USB Type C, and 2x USB Type A interfaces are supported)
• 2nd DisplayPort interface (single DisplayPort interface is supported)
These interfaces are identified with a grey color in the component placement pictures (opposed to the yellow
color).
