Troubleshooting

This section provides the answers to the most commonly asked questions. When this section doesn’t provide a solution, please contact the developer via hantune@han.nl, provide a description of what happened and make sure the errorLog.txt file is attached, which can be found in the HANtune folder. We will get back to your request as soon as possible (usually within one or two working days).

HANtune cannot start or hangs at the splash screen

This may be caused by an outdated version of the Java Runtime Environment (JRE).

Please check which version you have installed currently, by following these steps:

1. Click the windows home button
2. Type “cmd” and press “Enter” (command promt appears)
3. Type “java –version” (without the quotation marks) and press “Enter”

Make note of the message which appears in the command prompt.

In case the command prompt returns “Command not found”: install the Java Runtime Environment by going to the following website and download and install the JRE: www.java.com/en/download/ In case the command prompt returns something like: java version "1.8.0_101", please go to www.java.com/en/download/ and check whether you are running the most recent version of Java. If not, please download and install the latest version.

HANtune has crashed or stalled

Our policy during development and testing is to avoid all situations in which HANtune can get unresponsive or crashes. Unfortunately, not all situations can be tested and accounted for, so in case this has happened we would like to ask you to contact us via hantune@han.nl. Do not forget to add the errorLog.txt in your email attachment!

HANtune cannot connect

When HANtune cannot connect, usually it’s wise to first check the power supply and correct wiring. Finally it’s advised to use a debug LED (or blinking LED) to indicate that the target’s software is running. If this these three topics are okay, please proceed to the following hints:

XCP on CAN

When HANtune cannot connect via XCP on CAN, please check the following items:

• Are the communication settings correct?

Hint: Click the menu item “Communication” > “Communication Settings”. The “XCP on CAN” option should be selected. Go to the tab “CAN” and check whether the baudrate and CAN ID’s used for XCP communication are set according to the target’s running application.

• Does the CAN-bus comply to the CAN-standard?

Hint: Check the resistance between CAN high and CAN low. It should be 60Ω. Not 60Ω? Check the termination resistors.

• Is the CAN-dongle fully functional?

Hint: Check if the dongle is working correctly using PCAN-View(freeware).

• Does another application use the PCAN hardware driver?

Hint: Close all other application which might use the PCAN dongle, restart HANtune and reconnect.
