Link errors with a new project on a LM3S3748 EVB kit

Other Parts Discussed in Thread: LM3S3748

I just received a LM3S3748 EVB kit and have downloaded the latest CCS tools, 4.2.4.00033, and I am trying to create my own project based on the uart_echo project. I am familiar with eclipse IDE but the TI library structure is new to me.

 

I get the following link errors, I have just listed the first 3 errors

 

Severity and Description Path Resource Location Creation Time Id

errors encountered during linking; "RemoteTower.out" not built Remote Tower line 0 1314761856500 297

    Sounds like you are missing some of the Stellaris libraries in your build. The first three I believe are from "driverlib.lib"

    C:\StellarisWare\driverlib\ccs\Debug\driverlib.lib

    You'll need to include this file (--library option for the linker).

    Thanks

    Hi Dave,

    It sounds most likely like a linked resource problem - there are likely a few files or paths CCS is confused about and/or can't find. 

    How have you setup your project?  How have you included the UART library you refer to?

    You can find the include paths and settings as per the screenshots below.

    These are also likely to be good wiki pages for you regarding using Stellarisware libraries etc

    Thanks for all the responses. There 2 problems, 

     

    1) I needed to include driverLib

    2) Predefined symbol TARGET_IS_DUSTDEVIL_RA0 was needed.

     

    Thanks again.

     

    Dave
