9.2 On Target Platform – Run Time Update From File System

At runtime, you can use DCC tool’s live update function to override create time parameters. This results in an immediate effect of new parameters without the need for any code changes or restarting the application. The effect is similar to previous section, but the binary files are sent over Ethernet connection instead of being read from SD card.

For more details, see section Section 10.
