Hi,

Is it possible to transfer Audio data to/from DSP over the PCIe bus instead of the McASP?

Hi Abigail,

TI only supports PCIe driver for Linux which runs on the A72.

Therefore, it is technically possible to use OpenVX/GStreamer to transfer data between A72 and C7x. This will be similar to how camera data is transferred from CSI/USB interface to A72, then to C7x, then back to A72 to display: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/10_00_00/exports/edgeai-docs/common/edgeai_dataflows.html
