WM8731 slave mode BCLK signal always low

I am using the audio codec shield made for arduino (https://www.sparkfun.com/products/11290) with a DE0-NANO development board.

I am measuring the signals with a usbee AX pro

In the attached picture you can see that the I2C communication is working and ADDA_LCR signal is 44.1 KHz

The chip is configured to run in slave mode so the signals need to come from the FPGA.

I also attached the code i am using now
