MATLAB: Freescale Cup: Why do I get the error message “Warning: Unexpected Warning: A timeout occurred before the Terminator was reached”

Why do I receive the error message:
Warning: Unexpected Warning: A timeout occurred before the Terminator was reached.
Warning: Unexpected Warning: A timeout occurred before the Terminator was reached.
Warning: Unexpected Warning: A timeout occurred before the Terminator was reached.
Warning: failed to read expected serial data.
> In showCameraData at 75
My workflow is as follows:
I first open and build the "Line Scan Camera" model as instructed in the documentation. Next, when I execute the function "showCameraData" provided in the example "View Live Camera Data" from the Freescale Cup Companion App, I see the error message listed above. Why do I see this error?

Best Answer

This error message is displayed when the function "showCameraData" cannot read data from the COM Port specified. The following procedure will help you resolve this error.
1) Check the Device Manager in Windows and look for the COM Port with a label that begins with "OpenSDA-CDC Serial Port".
2) Next, execute the "showCameraData" function again and when prompted, provide it with the COM Port you found in the Device Manager.
