Request failed; bus grant (Error 171)
Cause: An attempt was made to execute a monitor command, but an external target
system device has monopolized the bus and the monitor is no longer responding.
Action: Wait until the processor has regained bus control, and then retry the
operation or don’t let external devices monopolize the bus for extended periods of
time.
Request failed; halted (Error 171)
Cause: During a monitor command, one or more target exceptions caused the
processor to stop running bus cycles.
Action: Use the emulation-bus analyzer to determine what exceptions caused the
problem and try to work around them.
Request failed; no bus cycles (Error 171)
Cause: During a monitor command, some problem caused the processor to stop
running bus cycles.
Action: Use the emulation-bus analyzer to determine what caused the problem and
try to work around them. If you are using the demo board, make sure the reset
flying lead from the probe is connected to the demo board.
Request failed; no target power (Error 171)
Cause: You do not have proper power applied to your target system or demo board.
Action: Check the connection from your emulation probe to the target system or
demo board. If using the demo board, be sure you have connected the external
power cable correctly.
Request failed; slow clock (Error 171)
Cause: The target system is providing target power but no clock signal.
Action: Make sure the clock oscillator is installed correctly.
