A.2 KD30 Problems
This section discusses the cause of the problem and countermeasures to resolve it. The common
problems encountered with KD30 are:
•
USB option cannot be selected from the initialization screen
•
Cannot connect to target
•
KD30 already exists
•
Issues that may come up during debug operations
A.2.1 USB Option Unavailable
When USB cannot be selected from KD30’s Init dialog box, you might be using an old version of
KD30 that does not support USB. Uninstall this version of KD30 and install latest version of KD30
from the \Tools\KD30 directory of the SKP CD.
A.2.2 Cannot Connect to Target
When the message ‘Can’t connect with the target’ is displayed after KD30 startup, there are
several reasons that may cause this message to appear. Each cause and the corresponding
countermeasure are discussed below.
•
The SKP is not connected correctly.
Please connect the ICD to your PC. Note: Regardless of whether the ICD is bus or target-
powered, please connect target board to ICD board first before plugging the USB cable to
your PC. Please see section 4 on system (SKP16C62P) connectivity.
•
The ICD has no power (Power LED on ICD is off).
Please ensure that the Power Mode switch on the ICD is on the ‘USB’ side. In ‘Target’
position, the ICD is powered from the target side.
•
USB was not selected on the Init dialog box.
Please select ‘USB’ from the Init dialog box that is displayed right after you start KD30.
•
The selected MCU on the ICD board and the actual target MCU (M16C/62P) do not
match.
Close the error message by clicking on ‘OK’ button, and then click on the ‘Cancel’ button of
the KD30 Init window to close KD30. Make sure you select ‘M30626FHP.mcu’. If the MCU
loaded on the ICD is different, KD30 will re-program the ICD to match it.
•
The target MCU is damaged.
Try a different target board and see if KD30 will come up as you may have a damaged board
or MCU.
