Finally got myself a oscilloscope. I guess it's a must when working on projects like this.

Found out that the CRS module sure have 1.8v output logic. Seems like the level shifter is not capable to replicate the signal:

CSR Clock signal - Green | Level shifter output - Yellow

I guess I need another level shifter to get this compo to work?

Yeah, it is possible that there is too much parasitic capacitance on the line so it cannot be driven to high and low levels in time. I suspect that you have this on a breadboard or something?
