Error using Cortex-R4 CMSIS DSP library

I tried the examples "arm_fft_bin_example" @ C:\ti\Hercules\Cortex-R4 CMSIS DSP Library\1.0.0\Examples. I modified the "File search path" under ARM linker in CCS project settings. Other than that, the fft example works fine.

This is a big endian example. Since you need the little endian one, you have to change the library included and the project settings.

You can find the documentation under C:\ti\Hercules\Cortex-R4 CMSIS DSP Library\1.0.0\Docs

Thanks for your answer.

The PDF included in C:\ti\Hercules\Cortex-R4 CMSIS DSP Library\1.0.0\Docs explained how to import a project in CCS (not very usefull...). Moreover, the project mentioned is in a directory which doesn't exist in the zip (\Lib\TI\CCS\arm_math_Cortex_R_b, i only have \Lib\ARM).

When trying to import arm_fft_bin_example, the compiler can not find any file while i changed the File Search Path (what did you changed exactly?).

Is the V5 of ARM Compiler necessary? (i havec TI 4.9.1)

I already changed settings and library to little endianness.

Thanks! But I did the same, and errors are still here : "the specified file is not found".

When i import file by file in a new project, I've got "attributes may not appear here" on several functions (__SIMD32(addr), __SMLALD ...).

How can i install compiler version 5.1?

Maybe i'm wrong... is this : http://www.ti.com/tool/hercules-dsplib availablefor RM48L952?

Yes. it is available for RM48952. I change my project to compiler version 4.95 (the lowest on my PC) and port it to the little endian. It compiles and runs. (I have not check the result). Please:

1. update your CCS ARM compiler to 4.95 or higher through the update maniger.

2. backup the arm_fft_bin**** folder in your PC.

3. Overwrite it with the zip file attached. 1464.arm_fft_bin_example.zip

4.Import it to CCS and let me know if it works in your bench

Meanwhile, I will look for ways to publish the compiler version 5.0.0.
