How to make official spi examples master and slave in one board.(slave can not work)

[yuming]

hi, I use the official example to change, the example need two board(one master and one slave), I am tring to make spi master and slave communication in one board, My board stm32f411ve. I use PortB13~15(spi2) and3~5(spi3), when I set both of spi2 and spi3 to be master, and MOSI connect to itselfs MISO, its work, and the value is right. When I set one of them to slave, MOSI(PB15)-MOSI(PB5) MISO(PB14)-MISO(PB4) SCK(PB3)-SCK(PB13)and it will time out error. this is my code.
