A.2 KD3083 Problems
This section discusses the cause of the problem and countermeasures to resolve it. The common
problems encountered with KD3083 are:
? USB option cannot be selected from the initialization screen
? Cannot connect to target
? KD3083 already exists
? Issues that may come up during debug operations
A.2.1 USB Option Unavailable
When USB cannot be selected from KD3083’s Init dialog box, you might be using an old version
of KD3083 that does not support USB. Uninstall this version of KD3083 and install latest version
of KD3083 from the \Tools\KD3083 directory of the SKP CD.
A.2.2 Cannot Connect to Target
When the message ‘Can’t connect with the target’ is displayed after KD3083 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 (SKP32C8x) 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 KD3083.
?
The selected MCU on the ICD board and the actual target MCU (M32C/8x) do not match.
Close the error message by clicking on ‘OK’ button, and then click on the ‘Cancel’ button of
the KD3083 Init window to close KD3083. Make sure you select ‘M30835FJGP.mcu’ or
‘M30855FJGP.mcu’. If the MCU loaded on the ICD is different, KD3083 will re-program the
ICD to match it.
?
The target MCU is damaged.
Try a different target board and see if KD3083 will come up as you may have a damaged
board or MCU.
