Audio FIFO Full interrupt(0x96) of ADV7511 occurs in rare cases.
Would you please enumerate the reasons to cause Audio FIFO Full?
In other words, where and what should we check?
Your advice would be big help for us.
If this occurs right after initialization it is not a problem, just clear it and continue.
If it occurs during normal operation, it mean that you I2S clock is faster then the clock that extracts the data from the FIFO and inserts it into the video stream. Check your I2C clock against the CTS/N values programmed into the part.
Thank you for your support.
I checked I2S Input signals, but it didn't seem that I2S has any problems.
Would you please tell us the alternative point we should check(e.g. register settings)?
Check the CTS and N registers based on your pixel clock. Also verify your pixel is really what you expect and not slightly below the target value.
