Startup and Operation

Introduction

This chapter supplies information for use of the MCPN750A family of Single Board Computers in a system configuration. Here you will find the power-up procedure and descriptions of the switches and LEDs, memory maps, and software initialization.

Applying Power

After you have verified that all necessary hardware preparation has been done, that all connections have been made correctly, and that the installation is complete, you can power up the system. The MPU, hardware, and firmware initialization process is performed by the PowerPC™ PPCBug power-up or system reset. The firmware initializes the devices on the SBC module in preparation for booting the operating system.

The firmware is shipped from the factory with an appropriate set of defaults. In most cases there is no need to modify the firmware configuration before you boot the operating system.

The following flowchart shows the basic initialization process that takes place during PowerPC system startup.

For further information on PPCBug, refer to Chapters 3 and 4 in this manual, or to the PPCBug Firmware Package User’s Manual.
