Xilinx EDK 12.4/ SPI Core 2.02 MISO help

Hi all,

 I am working with an Atmel Serial Flash Device (AT45XX series), I used xilinx's example code to transfer data in and out of my microblaze design. I oscped my MISO and MOSI lines along with SCK and slave select. They all seem to be behaving as they should.  Attached is the code I am mimicking. For some reason the XSpi_Transfer always returns with 0's in my read buffer. I double checked my pins, although I will do it again, but I can not get the data I see on the MISO line into my read buffer. Any suggestions?
