Re: eFPGA access to Voice subsystem data

Project qorc-sdk/qf_vr_apps/qf_1micvr_app shows the flow for audio data to circular buffer in M4 SRAM. This project is a good example for SDMA usage and the location of stored audio data. Project qorc-sdk/qf_apps/qd_helloworldhw shows the configuration for using M4 to configured eFPGA with Symbiflo...
