Hi All: I just received a TWR-K20D72M board today and am trying to compile the example code that came with it. Prior to receiving this board I downloaded the K20 72MHz example code and was able to compile several of the example projects. But when I tried to compile the twr-k20d72m-oobe.eww program that came with the TWR-K20D72M I ran into a number of problems that seem to be related to arm_math.h file and some of the include files. I added ARM_MATH_CM4 to the defined symbols and added cor_cm4.h, core_cmInstr.h, core_cmFunc.h, and core_cm4_simd.h to the build. When I try to compile the program I get a lot of “incompatible” errors that are related to the intrinsics.h file that is being read from my IAR arm libraries. I have tried to locate a newer intrinsics.h file that is compatible with core_cmFunc.h and common.h, but no luck so far. Can you shed some light on this problem?
