3–40 SROM Mini-Debugger Command Set
User Commands
rt
The return (rt) command exits the mini-debugger.
Control Flags
Not applicable.
Description
The return command exits the mini-debugger, returning to the calling program if
there is one. For the standalone mini-debugger, it simply exits.
Returning from a mini-debugger built into the SROMs provided with the
motherboards allows you to continue with the booting process, as if the mini-
debugger had not been invoked.
The rt command is also useful during debugging of SROM code you may write. You
can place calls to the mini-debugger throughout the SROM code to act as
breakpoints. You can then examine the system and CPU state at those points and
return to the SROM code to continue its execution.
For information on using the rt command during debugging, refer to the sources for
the EB164 motherboard SROM included in the Alpha SDK.
Example
An example of the rt command follows:
SROM> rt
