7.3.2 Target Configuration File

The target configuration file (.ccxml) helps to connect with one or more target hardware. With multiple target hardware for the given example, it becomes important to set the target configuration file appropriately to ensure successful connection to each device. Detailed documentation for the connection to multiple device and updating the serial number for the device has been provided in TI Documentation. Additional documentation on developing your own custom target configuration file and understanding the debug probe for the device can be found in the links provided, [1] and [2]. Steps to find and update existing target configuration are provided in Custom Target Configuration document.

Note: The target configuration file provided in the 'common' folder already has serial number configured for the devices, which is not the case for you. For the use case, you can either reprogram the serial number in the target configuration file or update the serial number of the debug probe through the steps mentioned in the provided links.
