Error Messages
Trigger duration out of bounds: <bounds> (2032)
Cause: This error occurs when you attempt to specify an external timing
trigger duration outside the valid range. A "greater than" duration must fall
within the range of 30 ns to 10 ms (and must be a multiple of 10 ns). A "less
than" duration must fall within the range 40 ns to 10ms (and must be a
multiple of 10 ns).
Action: Re-enter the command with the trigger duration within the bounds
shown.
Unable to break (608)
Cause: This message is displayed if the emulator is unable to break to the
monitor because the emulation processor is reset, halted, or is otherwise
disabled.
Action: First, look at the emulation prompt and other status messages
displayed to determine why the processor is stopped. If reset by the
emulation controller, use the break command to break to the monitor. If
reset by the emulation system, release that reset. If halted, try reset and
break to get to the monitor. If there is a bus grant, wait for the requesting
device to release the bus before retrying the command. If there is no clock
input, perhaps your target system is faulty. It's also possible that you have
configured the emulator to restrict to real time runs, which will prohibit
temporary breaks to the monitor.
Unable to configure break on software breakpoints (651)
Cause: The emulator controller cannot enable breakpoints, possibly because
the emulator is in an unknown state or because of a hardware failure.
Action: Initialize the emulator or cycle power, then re-enter the command. If
the same failure occurs, call your HP sales and service office.
Unable to configure break on write to ROM (650)
Cause: The emulator controller is unable to configure for breaks on writes to
ROM, possibly because the emulator was left in an unknown state or because
of a hardware failure.
Action: Initialize the emulator or cycle power. Then re-enter the command.
If the same failure occurs, call your HP sales and service office.
