7. If you intend to use PPCBug interactively, connect the terminal that
is to be used as the PPCBug system console to the
the front panel of the MVME2300SC.
In normal operation, the host CPU controls MVME2300SC
operation via the VMEbus Universe registers.
8. Replace the chassis or system cover(s), cable peripherals to the
panel connectors as appropriate, reconnect the system to the AC or
DC power source, and turn the equipment power on.
9. The MVME2300SC's green
confidence tests is run, and the debugger prompt
appears.
To ready the system console terminal for use:
1. Confirm that jumpers were installed on all bits on header J10 of the
MVME2300SC board as shown in
when the PPCBug firmware is used.
2. Connect the terminal via a cable to the DB9
See
Table 5-3
for pin signal assignments. Set the terminal up as
follows:
– Eight bits per character
– One stop bit per character
– Parity disabled (no parity)
– Baud rate of 9600 baud
9600 baud is the power-up default for the serial port on the
MVME2300SC. After power-up you can reset the baud rate if you wish,
using the PPCBug firmware's PF (Port Format) command via the
command line interface. Whatever the baud rate, some type of hardware
handshaking — either XON/XOFF or via the RTS/CTS line — is desirable
if the system supports it.
