Listening SPI communication between two ICs

hi everyone,
Two boards communicate via SPI, I try to read what master sends to slave and what slave responds with my STM32 eval board.
I simply connected 3 wires to CLK, CS and MOSI lines of master IC to three GPIO lines of my eval board and configured the lines accordingly. I try to read by polling the FLAG_RXNE, but no data arrives.
My question is: Is it possible to intervene SPI communication between two ICs with STM32100B-Eval board?
I wonder that since SPI communication is duplex, I need to use two SPI modules of STM32100B-Eval, but how?
Can you post an example?
