Confirm CCS Features

It is recommended to check the following CCS driver file if the CCS version is older than 11.1. The configuration of Cortex_R5 should be similar to Figure 2-1. If any line is missing, it is necessary to add the line showing in Figure 2-1. As for content of the lines, COM Port and Baud Rate need to be updated in target configuration file, which is included in the next step.
