Linux/AM3359: McASP LRCLK not working

AJINKYA PRABHU

Part Number: AM3359

Tool/software: Linux

I am trying to interface an I2S microphone (https://www.adafruit.com/product/3421) with BeagleBone Black,I have written the device tree:

I get a clock on pin 9_42 but no LRCLK on pin 9_27, and also when i measure the bit clock it seems to have a freqency of 24MHz, The .wav files are created when I run
