Description

This message is used during initialization (or re-configuration) by the application to

reset a board and download the code file that contains the operating software for the

board.

The download operation is supervised by the device driver that reads the binary format

code file and transfers it to the board.

The confirmation message (if requested) indicates success by status of zero. This

implies that the reset operation has commenced but does not imply completion. The

application must then wait until a Board Status Indication is received. This indicates

either successful completion of the reset and download operation or failure during the

procedure.

Parameters

board_type

The type of board to be reset. This must be set to 2 for DSI SPCI Boards.
