  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.
