Recently I have to work with a project on audio signal processing. I use Eval-BF5xx board with a CM-BF533 processor and an audio extension board. In my project, I must acquire audio signal data to do some further processing. I put a piece of code inside the interrupt handler EX_INTERRUPT_HANDLER(Sport0_RX_ISR) to invoke to the function that pushes data into the data buffer, but it seems that the interrupt event never raised. I set a breakpoint inside the interupt handler but it never reach there. I used initialization code just the same with the sample code of C_TalkThrough_I2S for ADSP-BF533-EZ Kit Lite. I don't know what wrong here. Is there any different configuration between two these boards?

Thank in advance!
