TDA4VM: Integrating C7 FFT lib into the pdk_jacinto (PSDK-RTOS 09.00.01.01)

Hi,

I have successfully applied the patch given in the below post in pdk_jacinto folder of PSDK RTOS 9.00.01.01 and now I can successfully build C/C++ files from PDK. 

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1071841/faq-tda4vm-how-to-build-c-application-from-j721e-pdk-is-there-a-demo-example-available

Now, I want to integrate C7 FFTLib into the pdk_jacinto folder of PSDK RTOS 9.00.01.01. I have a test application in PDK that plans to call the FFT high-radix decomposition functions. I am getting build errors when I update the makefile of my pdk test application by adding the relevant FFT C/C++ source files and linking fftlib_C7100.lib, and common_C7100.lib library files into my test project. Can you please guide me the steps needed to integrate the C7 FFTLib into the PDK?

Regards,

Attiya
