Hello Community
My customer has a problem about audio playing on i.MX6DL(With YoctoBSP 4.1.15_1.2.0).
Sometimes when it is playing an audio file, SSI becomes hangup and no sound outputs.
Registers of SSI(SSI3 is used) in normal case and abnormal case are as bellow(Left is abnormal and right is normal).
From the differences between abnormal and normal, it seems that there is no data in transmit FIFO when it became abnormal.
And registers of AUDMUX are the same.
And my customer measured the waveform of AUD_TXC, AUD_TXFS and AUD_TXD,it seems that it is no problem in abnormal case.(Above is normal and bellow is abnormal)
Could you give me some advice?
Best Regards

one can check hardware: power supplies and clocks as described in
i.MX6 System Development User’s Guide

From software side one can try minimal image, use Demo Images from
Is there log at hangup, had customer run ddr tester and updated image with new coefficients
from test.

Hi igor
Thank you for your reply!
I don't think it is helpful to me.
And the logs of normal case and abnormal case are the same, so can't get helpful information from logs.
