We see the thread that ever discussed it before. We still have something needing to clarify.
We have the connection described in the thread that we connect the codec BCLK and FS to I.MX7 RX_BCLK and RX_FS just like the sample picture in that thread. Does it work?
We see the description shows the TXC/TXFS can be slave or master mode. Does RXC/RXFS have the same feature or it just can be used as asynchronous mode?
In our board, currently, the TXC and TXFS is no connected and we just connect RXC and RXFS to codec to receive the signal.
