Chapter 10. Troubleshooting
10.1 When M306V0T-RPD-E Does Not Work Properly
(1) Emulator main unit cannot be powered up.
Check to see if the AC power cord is firmly plugged into the receptacle.
Check to see if the AC power 3P-2P converting connector is firmly connected.
(2) The M306V0T-RPD-E does not start up when the target system is connected with the PC4701
system. (The Error LED of the emulator main unit lights up.)
Check (1) described above.
Check whether the emulator main unit and the FLX120-RPD are firmly connected.
Check whether the FLX120-RPD and the M306V0T-RPD-E are firmly connected.
Check whether the M306V0T-RPD-E and the target system are firmly connected.
Check whether the power and GND are supplied to the target system.
Check whether switches of the M306V0T-RPD-E are firmly set. (Refer to Chapter 4. for setting
switches.)
Check whether the RESET pin and NMI pin are held 'HIGH' when the target system is
connected.
Check whether the HOLD pin and RDY pin are held 'HIGH' when in the microprocessor or
memory expansion mode.
Check whether the oscillator circuit of the target system is oscillating correctly when using a
target's oscillator.
Check whether correct firmware is downloaded in the emulator main unit. (Refer to the user's
manual of the emulator debugger about how to download firmware.)
(3) If the PC4701 system does not pass all self-checks (excluding when an target system error occurs),
there is the possibility of trouble in the system. In such case, contact the place of purchase.
Please take note that self-check should be executed under the following conditions.
• The target system is not connected.
• The Switch SW6 is set to 'L' position, SW7 to '16' (See Chapter 4).
When the condition does not improve even if you check the items above, troubles described below
are considered.
• Trouble of the evaluation MCU
• Trouble of the M306V0T-RPD-E
• Trouble of the PC4701 emulator main unit
