My customer is facing the issue that the RX from SSI by SDMA does not work on their custom board.
They use SDMA for TX/RX from/to SSI of i.MX6.
TX by SDMA works fine but RX does not work.
They use AUDMUX, SSI2 and AUD3 are used to connect with external DSP.
TXD, RXD,TXFS and TXC pins are used.
The following register dump is captured when the TX completion interrupt occurs.
i.MX6 is expected to receive audio data from external DSP at that time but no data has been received.
Do you have any ideas about the cause of this issue?
