Microblaze with AXI streaming interfaces

Hello,
         I am trying to connect my IP to the microblaze by AXI streaming
protocol. I have connected my IP to the microblaze using the AXI
streaming link M0_AXIS in XPS. But it seems that the microblaze does not
accept any data ie., the s_axis_tready never goes high. The below is the
code for micro blaze.

while(1){

     print("waiting for a packet...n");
      getfslx(temp,0,FSL_NONBLOCKING);
      temp2=temp;
      print(temp);
      print("getfsl passedn");
      putfslx(temp2,0,FSL_NONBLOCKING);
      print("putfsl passedn");
     print(temp2);
}
