Then, I'm trying to play sounds via WM8728 and have not hear any sounds yet. I checked SSI-3 signal set with an oscilloscope, no clock signal appears on SSI3_CLK. I tried the various SSI setting, I2S normal, I2S master, asychronous/synchronous, normal mode/network mode, ... But, I can't see clock signal, yet.
Is it just SSI3_CLK that produces no output or do you also see nothing on the I2S bit clock, frame sync and data signals?
I want to know an example setting to act i.MX' SSI as I2S clock master.
I'm not aware of any public examples of i.MX code other than what is in the ASoC git repository and the Freescale BSPs, and the only example I can see in ASoC git is for i.MX31.
