DEBUG Port

The RJ45 port labeled DEBUG on the front panel of the MVME240x

supplies the MVME240x serial communications interface, implemented

via a UART PC16550 controller chip from National Semiconductor. It is

asynchronous only. This serial port is configured for EIA-232-D DTE, as

shown in Figure 2-1.

The

DEBUG port may be used for connecting a terminal to the MVME240x

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. Refer to Chapters 5 and

6 for information about PPCBug.
