Hello guys,
I'm now having a setup with ADSP 21593 and A2B device, the SPORT 1A is set as TDM TX and SPORT 1B is set as TDM RX, and they all have a DMA list, when we are trying to apply a loopback feature, we want the data from SPORT1B directly going to the SPORT1A, the way we are using now is use a while(1) loopback and copy the data from buffer RX to buffer TX, but this will block the main function. Is there an non-blocking method to copy the data from one DMA to the other one? the TDM config are all the same one. by the way ,we try to let the adi_sport_DMATransfer of TX using the RX's DMA, but it seems not work.
