Tool/software: Code Composer Studio
Hello, I am using the tms320c6670 to implement the LTE Downlink PDSCH.
There is a question about using the FFT coprocessor. I want to use BCP to encode the data and then use the functionality of the fft engine.
The sample code 'FFTC_simpletestProject.c' provided by TI had an FFT size of 2048, and I tried using CP add function and FFT shift function.
I have also modified the example code and I am using FFT size 512, CP add and FFT shift enabled. However, it stops before the "Fftc_rxGetResult" function.
Disabling CP add and FFT shift does not stop.
Receive Buffer Starvation Error is expected when referring to user guide. So I increased the buffer size to the same size as the TI provided example code, but the pause continues.
I want to know how to solve it.
