Chapter 12: Emulator Error Messages
Software breakpoint: <breakpoint address> (Async_Stat 615)
Software breakpoint: <breakpoint address> (Async_Stat 615)
Cause: This status message indicates that the target program executed a software
breakpoint instruction (an execution breakpoint, either in software or provided by
one of the eight hardware breakpoint resources). The emulator stopped the target
program and began running in the monitor.
Software breakpoint break condition is disabled (Error 661)
Cause: You disabled the software breakpoint feature. Breakpoints are enabled by
default. Then you attempted to set a breakpoint, or you attempted to single step
with the foreground monitor (either the built-in or custom foreground monitor).
Action: Re-enable the software breakpoint feature and try again.
Specified breakpoint not in list: <address> (Error 663)
You tried to enable a software breakpoint that was not previously defined.
<address> prints the address of the breakpoint you attempted to enable. Insert the
breakpoint into the table and memory.
Stack pointer is odd (Error 80)
Cause: You tried to modify the stack pointer to an odd value and the emulator
expects the stack to be aligned on a word boundary.
Action: Modify the stack pointer to an even value.
Step display failed (Error 688)
Cause: System failure or target condition.
Action: Check memory mapping and configuration questions.
Stepping aborted (Error 685)
Cause: This message is displayed if a break was received during a step command
with a stepcount of zero (0). The break could have been due to any of the break
conditions or a <CTRL> c break.
