This example performs FSI TX to FSI RX internal loopback in DMA mode. The application configures an instance of FSI TX and FSI RX module with below configuration
With above configuration, the application transfers 100 frames of data from FSI TX, waits for data to be received by FSI RX. EDMA completion interrupt is configured once all the data, tag and user data is transmitted/received.
Once the transfer completes, it compares the source and destination buffers for any data mismatch.
