TDA4VM: Compilation Error Using FFTLIB – Undefined Identifiers

Part Number: TDA4VM
Other Parts Discussed in Thread: FFTLIB

Tool/software:

Hello,

I am trying to use the FFTLIB on the C71x DSP from the TDA4VM. To test the library, I created a simple project with only a main function and included the FFTLIB headers. I am using Code Composer Studio (CCS) and have configured the project settings according to the documentation.

However, when I try to build the project, I get the following compilation errors:

"C:\ti\ti-processor-sdk-rtos-j721e-evm-10_00_00_05\fftlib\src\common/FFTLIB_types.h", line 393: error #20: identifier "__HWA_CONFIG_REG_v1" is undefined

It looks like these identifiers (__HWA_CONFIG_REG_v1, __HWA_OFFSET_REG, etc.) are missing. I suspect there might be a missing dependency or preprocessor definition.

Additional Information:

Processor: C71x (TDA4VM)
SDK Version: ti-processor-sdk-rtos-j721e-evm-10_00_00_05
IDE: Code Composer Studio
Project Configuration: I have added the FFTLIB include paths and linked the necessary libraries in the project properties.

Questions:

Do I need to include any additional headers or define specific macros to use FFTLIB properly?
Is there a dependency (e.g., HWA or another library) that must be included for FFTLIB to work?

Any guidance would be greatly appreciated. Thanks in advance!

Hi,

It looks like this is the continuation of your previous thread, TDA4VM: Issues Using FFTLIB on DSP C71x of TDA4VM with TI Processor SDK RTOS.

Can you share the cmake configuration for your simple project?

Thanks.

Hi,

Thanks for your response!

This is indeed related to my previous thread. I was able to resolve the build issues when using CMake, but I am still facing issues when trying to use FFTLIB directly in Code Composer Studio (CCS).

Regarding your question, my project does not use a manually created CMake configuration. Instead, I am using the build system automatically generated by CCS. The project is configured to link against the FFTLIB library, and the makefile generated by CCS contains the following settings:

Hi ,

Have you selected the MMA version. If not please select option 1.

After that check the summary of flags set and verify whether MMA path is set or not.

Regards,
Sivadeep

Hi,

Oh, I don't know how I hadn't seen that before! I've selected it, and it worked!

Thanks again for your help, really appreciate it!
