Checkpoint
Check all emulator debugger settings, interface cable
connection and switches on the rear of the PC4701 match.
See the user's manuals of the PC4701 and emulator
debugger.
(1) Download the proper firmware.
See "4.2 Downloading Firmware" (page 32).
(2) Recheck the connection between the PC4701, this
product and pod probe.
See the user's manual of the pod probe
See "3.3 Connecting the PC4701 and Emulation Pod"
(page 26).
Download the proper firmware.
See "4.2 Downloading Firmware" (page 32).
(1) Check the reset pin of the target system is pulled up.
(2) Check the reset pin of the target system has changed
from "L" to "H" level.
(1) Check the NMI* pin is "H" level.
(2) When in memory expansion or microprocessor mode,
check the RDY* and HOLD* pins are "H" level,
respectively.
(3) If the reset circuit of the target system has a watchdog
timer, disable the timer.
(4) Check power is properly supplied to the target system
and that the target system is properly grounded.
(5) The program may be uncontrollable in areas memory
not allocated. Recheck the map setting.
See "4.3 Starting up the Emulator Debugger (Setting
EMEM Dialog)" (page 33).
(6) The contents of an MCU file varies with the version of
the emulator debugger M3T-PD79. Check the current
MCU file is the one included with your emulator
debugger M3T-PD79.
(7) The flash ROM of the MCU may be worn-out. Contact
your local distributor.
(1) Check the oscillation circuit of the target system is
oscillating properly.
(2) Check the switches in the pod probe are correctly set.
See the user's manual of the pod probe.
Check power is properly supplied to the target system and
that the target system is properly grounded.
Recheck the connection of this product, pod probe and
the target system.
See the user's manual of the pod probe.
Check the program is not accessing to the unused area.
