I am trying to build and use FFTLIB from the lates RTOS SDK J722S EVM (10_01_00_04) on the BeagleY-AI, but have had little success. Is there anyone who has successfully implemented FFT on the c7x DSP of the BeagleY-AI, or have some insight on how to do it? I am also curious to know if there are some example projects on how to communicate between the OS and the DSP, to f.ex. running a python program that does FFT on the DSP.
I have compared the library to Olofs Hello world tutorial (Hello world on the C7x DSP coprocessor with the BeagleY-AI | by Olof Astrand | Medium), and have noticed that the FFTLIB tests do not include a resource table. How should I adjust the linker file to include a usable resource table?
If this is a wrong approach to utilizing the c7x DSP, please let med know.
