Enable J-Link log file

Enable J-Link Log File

Software which uses the J-Link DLL to include J-Link support (e.g. IDEs), can implement an option to specify a J-Link log file. As this is no must, the J-Link log file can also be set / overwritten using the J-Link Control Panel. This allows to create a log file independent of the used software. Please note, right now the J-Link Control Panel is available in the windows software package, only.

Following steps needs to be done to configure the J-Link log file using the J-Link Control Panel:

1. Open the J-Link Commander
2. Click the small green J-Link icon in the windows task bar
3. Switch to the Settings tab in the J-Link Control Panel
4. Check the Override checkbox in the Log file section and specify a path to the log file
5. Close the J-Link Commander
6. From now, any J-Link DLL based application uses the J-Link log file override

The override option can be used in any application to create the J-Link log file as it is a global override.

J-Link Commander

The J-Link Commander allows to configure the J-Link log file using the "log <LogFilePath>" command.

J-Link GDB Server

The J-Link logfile can be enabled by passing the -log <Path> command via command line option to the J-Link GDB Server.

The J-Link log file can be enabled using the User Actions function int Project.SetJLinkLogFile(const char* FileName);. We recommend to add this function call in the OnProjectLoad() project function. For further information regarding this, please refer to the Ozone User Manual (UM08025).
