Hiпјљ

when I loopback audio by SPORT TDM8 in DMA modeпјЊI have place all audio buffer in L3, and DSP-CORE0 copy(memcpy) the rx audio to a temp buffer then copy the temp buffer to tx audio buffer. I found that the audio sounds normal both using cache mange API(flush_data_buffer(x, x, ADI_FLUSH_DATA_NOINV), flush_data_buffer(x, x, ADI_FLUSH_DATA_INV)) or not, why ?
