Hi, sir:
My board's sound card can work well when use default mcasp3 interface. When I modify some configuration in order to use mcasp4 as an output of sound.
Of course, I use logic analyzer to watch the output. Because mcasp4 in my board doesn't connect to any codec. But I can't watch any waveform in mcasp4.
Strangely, there is output of frame sync and clock in mcasp3 interface.
I modify 2 places.
1. change .dts file to fit mcasp4.
2. change mux_data.h file to fit pin mux.
If any other modification should I make? This problem bother me a lot ! Any advice will be appreciate ! Thanks !
