Hi,
you can easily load new LDF file into LIN stack component. The file should be copied into the project directory. Then LDF file is selected within "Network Configuration" tab. The LDF file is automatically parsed and its contents is reflected to LIN Slack component GUI. You can do modification of the parameters in the GUI's tabs and changes are automatically saved into the selected LDF file. "Validation of changes .." message is displayed in Progress bar or window.
The Reload button can be useful if you modify LDF file in S32DS text editor as other source file. After you save the file after Reload is pressed new contents is reflected in the LIN Slack component GUI.
After PE code is generated the node configuration files (lin_cfg.h and lin_cfg.c), that are needed for LIN Stack, are updated based on LDF file.
BR, Petr
