b.Copy the fousb.sys and usbmon.sys files from the C:\Renesas\FoUSB\USB Drivers folder to the \WINNT\SYSTEM32\drivers folder.

Windows 98 or XP

a.Copy the fousb.inf and usbmon.inf files from the C:\Renesas\FoUSB\USB Drivers folder to the \WINDOWS\INF folder.

b.Copy the fousb.sys and usbmon.sys files from the C:\Renesas\FoUSB\USB Drivers folder to the \WINDOWS\SYSTEM32\drivers folder.

A.3 Debugging Problems

This section discusses the cause of the problem and countermeasures to resolve it. The common problems encountered with debugging are:

Erratic debug behavior

Cannot connect to target

Issues that may come up during debug operations

A.3.1 Erratic Debug Behavior

HEW allows you to launch multiple instances of itself. However, if more that one instance of HEW is open during a debug session, erratic behavior can result. Running the FoUSB Programmer at the same time as HEW can also result in erratic debug behavior. Lastly, having more than one ICD installed can also cause erratic problems or cause HEW to crash.

A.3.2 Cannot Connect to Target

When the message “Can’t connect with the target” is displayed when attempting to connect, there are several reasons that may have caused this message to appear. Each cause and its corresponding countermeasure is discussed below.

The ZDK board or the ICD are not connected correctly.

Unplug the ICD from the USB cable. First connect the ZDK target board to the ICD via the supplied 2×5-header ribbon cable, then connect the ICD back to your PC’s USB port via the supplied mini USB cable. Please see section “4.0 System Connectivity”.

The ICD has no power (Power LED of the ICD is off).

Please ensure that the Power Mode switch on the ICD is set to ‘USB’, and that the power switch on the ZDK board is set toward the ICD connector, if you want to power the board from the ICD unit. If you want to power the ICD from the ZDK target board, the ICD power mode switch must be in the ‘Target’ position. The target board then must be provided with its own power supply and the target board’s power switch must be on in the correct position (toward the power connector).
