Creating an external module

Dear all,

 

I am trying to implement a real time FFT with CrossCore in order to do frequency domain audio processing. I am using the ADSP-21479. My aim is to create a custom SigmaStudio to ease future development (I do not wish to use the FFT blocks SigmaStudio already has).

 

I am quite new to CrossCore and to DSP programming so I am having troubles figuring how all this works... For now, I tried to implement a simple block that just copies the input to the output, following the instructions given by the Algorithm Designer.pdf doc. I cannot seem to build the project correctly. Instead, I get the following error:

 

[Error li1021]  The following symbols referenced in dynamic 'p0' could not be resolved:

        'main [_main]' referenced from '.\system\startup_ldf\app_startup.doj'

 

Linker finished with 1 error

cc3089: fatal error: Link failed

make: *** [TEST_EXT_MODULE.dxe] Error 1

 

I am really stuck here, so I would be grateful if you could have a look at my project (attached to this post) and tell me what i did wrong.

 

Thanks for your help,

Regards.

Stephane.
