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.
