3–6 Remote Debugging
Starting a Ladebug Session
3.7 Starting a Ladebug Session
The Debug Monitor ladebug command configures the motherboard as a remote
debugger target. Communication is performed through the Ethernet connection.
To debug a program running on a motherboard using Ladebug running on a remote
host, follow these steps:
1. Set up the host DIGITAL UNIX machine as described in Chapter 2.
2. Start the motherboard.
3. Load the program into memory on the motherboard.
4. Set a breakpoint in the program.
5. Execute the program. The program will stop at the breakpoint and print the
instruction line at that location.
6. Issue the ladebug command. This causes the motherboard to wait for a
connection from Ladebug.
7. From the host system, enter the command to start Ladebug and cause it to
connect to the motherboard.
The following example shows how to set up a sample session:
