(2) The following messages are displayed in the action log window and the flash memory programming mode
cannot be entered.
ERROR(E012):Connection or synchronization failed
ERROR(E014):Connection or synchronization failed
[Cause 1]
The connection between the target system and FP5 may be incorrect.
[Action 1]
<1> Connect the SO/TxD and SI/RxD signals from the FP5 with TxD (SO) and RxD (SI) of the target device so that
signal input/output are consistent.
FP5 Target device
SO/TxD TxD (SO)
SI/RxD RxD (SI)
<2> The target interface must be isolated from other devices, using jumper switches or the like; otherwise,
malfunction may occur. Refer to CHAPTER 10 NOTES ON TARGET SYSTEM DESIGN, CHAPTER 11
SPECIFICATIONS OF TARGET INTERFACE CIRCUITS or the user’s manual of the target device. Moreover,
monitor the actual waveform to confirm that the signal is not distorted and the signal level is correct.
[Cause 2]
Connection of pins for other than for the target interface may be incorrect.
[Action 2]
Refer to CHAPTER 10 NOTES ON TARGET SYSTEM DESIGN or the user’s manual of the target device.
[Cause 3]
The PR5 file selected in the [Parameter and Setting file] area on the [Target] tab in the Device Setup dialog box
may not be correct.
[Action 3]
Use the PR5 file that supports the target device.
For details on PR5 files, refer to 1.3 Supported Devices and 4.3.3 (12) (a) [Parameter and Setting file] area.
[Cause 4]
The clock may not be able to be supplied to the target device.
[Action 4]
<1> Check the settings in the [Supply oscillator] area on the [Standard] tab in the Device Setup dialog box. For the
correct settings, refer to the supplementary materials for the PR5 file or the user’s manual of the target device.
<2> Check the clock supply on the target system by means such as waveform monitoring.
