  2. Download the program to the target board.

  3. Power on shield dock board then power on development board.

Run the example

  1. Download this program to the board.

  2. Connect the displayer to the MinDP port (J2).

  3. Connect one video source (like: “the shield host board (om13790host)” or “PC”) to the Type-C port (J1). For example: if the video source is PC, connect the shield dock board to PC with one Type-C cable.
