Hello Caleb
thanks for your help
Here's my current dts
I want to use ssi1 on port 4
I added #sound-dai-cells = <0>; on ssi1 because simple card complaijning
about it (what is that?? I could not find documentation about it)
Now the driver says:
asoc-simple-card sound.26: snd-soc-dummy-dai <-> 2028000.ssi mapping ok
and
> aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: D2028000ssisnds [2028000.ssi-snd-soc-dummy-dai], device 0:
2028000.ssi-snd-soc-dummy-dai snd-soc-dummy-dai-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
> aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
sysdefault:CARD=D2028000ssisnds
2028000.ssi-snd-soc-dummy-dai,
Default Audio Device
but if I try to play a file it hangs and nothing escape
How I can debug the various modules? ssi, dma, ???
how I can print debug messages?? (i cannot see the various dev_dbg no
matter what I try...)
