    Hello

    I think you need to add ARM_MATH_CM4 like as shown in CM4.jpg

    There is a lab for this board that has a DSP example you can try out:  www.keil.com/appnotes/docs/apnt_233.asp
    I added the CMSIS-DAP library as shown in DSP_Lib.jpg
    Download the lab and see if you can get the DSP example to work.  Hopefully it will help.
