Audio Codec IP core UP

Hi, 

 

I'm trying to use the audio core with the Nios IDE. Well, i think that i had no problems to link the libraries for the nios IDE. My problem is when i use the functions of the core.  

 

My code do this: 

 

- First i open the device with alt_up_audio_open_dev. The datasheet mention that the parameter of this function use only the name in the SOPC builder but it doesn't compile. So I check the system.h and found that the audio module is named# define AUDIO_0_NAME. 

 

- Now I read read the fifo with the function : alt_up_audio_read_fifo. I add some code to print the return of this function. The first time it return the number of words that i put in the function, but when i reset the system, it only read 2 or 1 word from the fifo. 

 

Maybe someone can help me with this. 

Thanks,
