Wind River's Scout reference design is a single board computer (SBC) that enables development to begin before the hardware is available. This board offers a solid platform for bothhardware and software engineers to use in evaluating and prototyping designs that closely parallel their final applications. The Scout also gives software engineers a live target on which to begin developing and testing application code.Like all Wind River reference designs, the Scout comes complete with detailed schematics, board support package (BSP), user documentation, and power supply.The Scout reference design combines Motorola's high performance MPC750/755 RISC and MPC8260 microprocessors for multi-processor master/slave functionality.The major focus of the Scout design is to evaluate systems that use the high performance MPC7400 with a backside L2 cache as the system processor, and use the integrated communication and memory controller features of the MPC8260. In this companion mode, the PowerPC processor inside the MPC8260 device is disabled. A configuration option will allow the user to enable the MPC8260 processor, thus enabling a multi-processor system. This option is not recommended due to limitations in the power on reset sequencing.
