Chapter 13: Error Messages
Terminal Interface Messages
100 No response from monitor
Cause: The main cause of this error message is when the target system does not
assert RDY for target memory and I/O accesses.
Action: Do not attempt to access target locations that don't return RDY.
102
Monitor failure; no clock input
Cause: The monitor is unable to run because no emulation processor clock is
available.
Action: Make sure a clock meeting the microprocessor's specifications is input to
the clock pin of the target system probe.
103 Monitor failure; no processor cycles
Cause: The monitor is unable to run since the processor is not running. The
monitor is unable to determine the cause of the failure.
Action: If running in-circuit, troubleshoot the target system.
104
Monitor failure; bus grant
Cause: The monitor is unable to run. The emulation processor is not running
because it has granted the bus to another device.
Action: Wait until the processor has regained bus control, then retry the operation.
105
Monitor failure; halted
Cause: The monitor is unable to run because the processor is halted (due to an
external halt line or a halt instruction).
Action: Release the external halt and retry the operation. If the processor halted
due to a halt instruction, try the reset command, then retry the operation.
106 Monitor failure; wait state
Cause: The monitor is unable to run because the processor is in a continuous wait
state.
Action: A continuous wait state may indicate target system problems.
Troubleshoot the wait line.
