Note: The examples will show usage of SW modules and APIs on a specific CPU instance and OS combination.
Unless noted otherwise, the SW modules would work in both FreeRTOS and NORTOS environment.
Unless noted otherwise, the SW modules would work on any of the CPU present on the SOC.
Unless noted otherwise, the SW modules would work on all supported EVMs

Extra Installation (On top of default CCS Installation)

To use this SDK, SysConfig version 1.11.0 build 2225 should be installed separately on top of the default CCS location.
Contact the TI representative to get access to this SysConfig version
Once the installation is complete (use default path), copy the sysconfig_1.11.0 build folder to CCS folder C:/ti/ccs1040/ccs/utils as well. This is needed to use CCS projects from CCS
