running fft example code

Ravikumar Chintoju

Hello every one,

we are trying to develop an acoustic application on c6472 multicore dsp.

we have downloaded the DSP lib form http://www.ti.com/tool/sprc265 and installed it.

Now i'm trying to run the FFT example code given along with this library on CCSv5.2. 

we are getting one error in the build that it is not able to open #include <ti/dsplib/dsplib.h> even though this header file is existing.

now i have searched through literature for the solution. i have seen how to build dsplib before running  actual program at file:///C:/ti/dsplib_c64Px_3_2_0_1/docs/doxygen/html/building.html

i followed the procedure as mentioned in this html document. i have downloaded "code generation tools" and installed.

now, i have selected to import existing eclipse project from the path :packages/ti/dsplib/lib

but i'm getting following error:

See details below.
Error: Import failed for project 'DSPLIB_LIB_GEN' because its compiler definition is not available. Please install the C6000v7.4 compiler before importing this project.

why is this happening? i have already installed compiler verc6000V7.6. where can i be wrong? how to link this DSP lib in CCSv5.2? how to run FFT example code? kindly help me

Thanks,

Ravikumar

    I'm suprised you are using CGT7.6, as it is not intended for general use at this point.  You must have downloaded it separate from CCS.  It is currently only used for MCSDK-HPC in C66x for use with multicore programming models.  I don't believe it will give you anything above and beyond the CGT7.4 for your usecase.  Please try installing CGT7.4 and trying that.

    Regards,
