    Hi,

    Yes, you need to add the files to the make file.

    Please check the SDK UG

    Thank you

    The error shown is a simple coding problem.  It is usually flagged as a warning, not an error.  What the error is saying is that the variable is defined, such as:

    int errCode;

    Then it is used, for example:

    errCode = myfunction();

    But then the variable is never again used.  In this case, there's no point for errCode to exist at all.

    There are two ways to fix it.  Either delete all references to errCode, or add a piece of code following the function call like this:

    if (errCode != 0)

       printf("The function returned an error\n");

    That will solve the compile error, but you make have a linker error if the lib has not been referenced in the makefiles.  Make sure you read about the watchdog functionality so that you do not then have an error when the program runs.

    Hi 

    i can't find page about how to add library path into makefile.

    could you point which page describe about add file to make file.

    thanks

    You haven't mentioned what you are building.  If it's the MSS portion of the demo, the makefile you want is:

    C:\ti\mmwave_sdk_02_01_00_00\packages\ti\demo\xwr16xx\mmw\mss\mss_mmw.mak

    See the section of the makefile I pasted below.  Look at the two lines that include the UART driver.  Copy each of those lines replacing uart with the driver you are adding.  Make sure your editor does not strip off trailing whitespace or the makefile will be broken.
