The data line has data when the FS is high (when FS is low, that data line has 0). So this is correct Left Justified.
At least it seams that McBSP is actually shifting out the data at the correct place, when it is slave..
Oh, and I can not explain why this is working, but I do trust on my scope, and it shows me that it is correct :o
For me it looks it's working because of NB_IF so try again with NB_NF :-)
Oh yes :D You know, I was looking at the diff between the I2S and LEFT_J polarities, but did not noticed NF vs IF... Yes, you are right, I need to invert the FS in a similar fashion as we do with the DSP modes.
Thanks for spotting it, I'll send the fixed patch with inverting the FS in case of LEFT_J
