Chapter 12: Emulator Error Messages
MMU is not enabled via configuration (Error 160)
MMU is not enabled via configuration (Error 160)
Cause: You tried to display MMU translations or load the deMMUer but the MMU
is disabled within the emulation configuration.
Action: If you wish to use the MMU, enable it in the emulation configuration
before attempting to display its translations or load the deMMUer.
MMU is not enabled via translation control register (Error 160)
Cause: You tried to display the MMU translations or load the deMMUer. While
the MMU is enabled within the emulation configuration, the enable bit is not set in
the translation control register.
Action: Either enable the MMU in your target system by modifying the TC register,
or specify an enabled value for the TC register on the command line when invoking
the MMU or deMMUer commands.
Monitor address is not set to <addr> for downloaded monitor (Error 144)
Cause: You have downloaded a custom foreground monitor which was linked at an
address other than the monitor address specified within the emulation configuration.
Action: Change the monitor address within the emulation configuration or link your
custom monitor at the address specified in the configuration.
Monitor operation interrupted by target system (Error 173)
Cause: Your attempt to execute a monitor command was aborted when the target
system preempted the monitor and did not return control. When the foreground
monitor is running and is in its idle state, the monitor can be interrupted by the
target system to service target system requirements. If the target system interrupts
the monitor and fails to return control to the monitor after it has finished, this error
is generated. The emulator does not attempt to regain control when after the
monitor has been preempted.
Action: The only way to regain control of your emulation system is to reset the
emulation processor. If you do not want the monitor to be preemptable by target
system interrupts, you can increase the monitor interrupt priority level. Refer to
Chapter 8, "Configuring the Emulator."
