DEBUG Port

The RJ-45 port labeled DEBUG provides an RS232 serial communications interface, based on
TL16C550 Universal Asynchronous Receiver/Transmitter (UART) controller chip. It is
asynchronous only. For additional information on pin assignments, refer to

Chapter 6, Pin

Assignments

.

The DEBUG port may be used for connecting a terminal to the MVME5100 to serve as the
firmware console for the factory installed debugger, PPCBug. The port is configured as follows:

8 bits per character

1 stop bit per character

Parity disabled (no parity)

Baud rate = 9600 baud (default baud rate at power-up)

After power-up, the baud rate of the DEBUG port can be reconfigured by using the debugger’s
Port Format (PF) command.

2.3

System Powerup

After you have verified that all necessary hardware preparation is done, that all connections
were made correctly and that the installation is complete, you can power up the system.

2.3.1

Initialization Process

The MPU, hardware and firmware initialization process is performed by the PPCBug firmware
upon system powerup or system reset. The firmware initializes the devices on the MVME5100
in preparation for booting an operating system.

The firmware is shipped from the factory with an appropriate set of defaults. Depending on
your system and specific application, there may or may not be a need to modify the firmware
configuration before you boot the operating system. If it is necessary, refer to

Chapter 3,

PPCBug Firmware

for additional information on modifying firmware default parameters.

The following flowchart in

Figure 2-1

shows the basic initialization process that takes place

during MVME5100 system start-ups.
