(2) Errors Occur When the Emulator Debugger Starts Up

(When the target system is connected)

Table 6.2 Checkpoints of errors when starting up the emulator debugger (target is connected)

Error Checkpoint

Communication error occurred

Data was not sent to the target

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 the emulator debugger.

Target system cannot be properly built

(1) Download the proper firmware.

See "4.2 Downloading Firmware" (page 50).

(2) Recheck the connection between the PC4701 and this product.

See "3.5 Connecting the PC4701 and Emulation

Pod" (page 38).

PD30 version is not the same version as the firmware in the target

Download the proper firmware.

See "4.2 Downloading Firmware" (page 50).

Target MCU is in the reset state

Target MCU cannot be reset

Check the reset pin of the target system has changed from "L" to "H" level.

(1) Check the RESET* pin and NMI* pin are "H" level.

(2) If in memory expansion mode or microprocessor mode, check the RDY* pin and HOLD* pin are "H" level.

(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 where memory not allocated. Recheck the map setting.

See the user's manual of the emulator debugger.

Target is in HOLD state

Target clock is stopped

Target MCU is not receiving power

(1) The MCU is either in the stop mode or wait mode.

Either reset the MCU or cancel the mode with an interrupt.

See the MCU specifications.

(2) The program may be uncontrollable in areas where memory not allocated. Recheck the map setting.

See the user's manual of the emulator debugger.

(1) Check the oscillation circuit of the target system is oscillating properly.

(2) Check the switches in the emulation pod are correctly set.

See "3.2 Setting Switches and Pullup Resistors"

(page 29).

Check power is properly supplied to the target system and the target system is properly grounded.
