Debugging Embedded Code

To set a breakpoint at address 0x8080B0AA, enter this address as part of the Breakpoint (br)
command:

The Picobug prompt reappears, confirming that the system set the breakpoint:

To see the list of breakpoints, enter the Breakpoint (br) command without any address value:

The system responds with the addresses of breakpoints, in this case only the breakpoint set
in step 8:

10.

To start program execution, enter the Go (g) command:

In this instance, the breakpoint set during step 8 stops code execution. The system responds
with this new display of register values:

11.

To remove all breakpoints, enter the No Breakpoint (nobr) command, without any address
value:

The Picobug prompt reappears, confirming that the system has removed the breakpoints:

12.

To see the list of breakpoints again, once more enter the Breakpoint (br) command without
any address value:

As there are no longer any breakpoints, the system responds with the Picobug prompt:

13.

To continue with this example session, enter another appropriate command. For example,
to resume program execution, enter the Go (g) command.
