EVM6418 Test Example
A variant of the board’s production test code is provided with the EVM6418 as a confidence test (every board passes a superset of these tests before it ships) and as an example of how to manipulate the various board components. You can find the code in :
c:\CCStudio\boards\evm6418\examples\test.
Test status is shown in the Code Composer output window.
External Connections
For UART tests you must have an external loopback connector attached to the RS-232 port to act as a loopback path.

Configuring the Tests
Only tests that can complete without external connections are enabled by default. To enable/disable a test simply comment or uncomment the corresponding TEST_execute() call in main().
