This boards share SPI with NRF24 connector and on board flash.

STM32F405VE

NRF24L01 (JP2)
1 GND
2 3V3
3 PB6 NRF_CE
4 PB7 NRF_CS
5 PB3 SPI1_SCK
6 PB5 SPI1_MOSI
7 PB4 SPI1_MISO
8 PB8 NRF_IRQ

SPI Flash W25Q16 (U3)
1 PB0 F_CS
2 PB4 SPI1_MISO
3 WP 3V3
4 GND
5 PB5 SPI1_MOSI
6 PB3 SPI1_SCK
7 HOLD 3V3
8 VCC 3V3 

So, I connected PB0 and 3V3, and attached a module to the NRF24 connector.
It should work with the following settings, but it doesn't work for some reason.

Nrf24l Mirf = Nrf24l(PB6, PB7);
