TDA4VM: Running fftlib codes from TI on DSP C7X on CCS

Tool/software:

Hi TI,

I'm trying to create a project on CCS in order to test the FFT algorithm provided by TI in the fftlib folder.

For the moment, I've only done the bare minimum to check if the configuration is okay. Indeed, I added the paths required for the compiler and linker in the project properties, and I added the .lib libraries. Then, I tried to compile the project, which only contains the following main:

#include <fftlib.h>



int main(void)
{
	return 0;
}

However, when I try to compile it, I get those issues :

>> Compilation failure
subdir_rules.mk:9: recipe for target 'main.obj' failed

Could someone help me with that ?

Hi Mélanie,

Could you please let me know the following:

Which compiler version and PSDK version are you using?
Which CCS version are you using?
Which build configuration are you using (Debug or Release)?
Are you building on a Windows OS?

Regards,
Sivadeep

Hi Sivadeep,

- The version of compiler is ti-cgt-c7000_4.1.0.LTS and the PDSK version is psdk_rtos_auto_prebuilt_07_00_00

- I'm using the 12.6.0.00008 CCS

- I'm working on a Release configuration

- I'm using CCS on a pc with a windows OS if that's your question

Regards,

Mélanie

Hi Mélanie,

Can you please check if you have given the target processor version as 7120.

Hi,

The target processor version is 7100

Could you explain me why I should put the 7210 version ? I do not understand

Hi,

Could you please confirm the library path and the library you added in CCS.

Hi,

Yes sure

For the include options in the C7000 Compiler, I added the following path : T:\Packages\ti-processor-sdk-rtos-j721e-evm-10_01_00_04\fftlib\src

For the C7000 linker:

- I added for the library path : T:\Packages\ti-processor-sdk-rtos-j721e-evm-10_01_00_04\fftlib\lib\Release

- I added the following librairies : FFTLIB_C7100.lib, FFTLIB_common_C7100.lib and FFTLIB_test_common_C7100.lib

Regards,

Mélanie

Hi,

Thanks for sharing the paths.

Please ignore my previous comment about changing to c7120. You can use c7100.

Can you please check if you have enabled MMA. If not can you please change the following and check

I had enabled MMA while using c7100, so it doesn't explain the current issue

The error you mentioned typically occurs when MMA is disabled. Are you still encountering the same error after enabling MMA?

If so, please share a screenshot of your configuration settings.

Okay, now it works. I believe I may have modified this value inadvertently.

However, it still have a question : which code from the FFTlib could I use to execute a FFT algorithm on a 2D buffer ? I want to run it on the C7x

Thanks for the update.

I don't think there is support for the same.

Since this original question for this thread is answered can we go ahead a close this thread please.
