Hello I want to connect to the STEVAL-MKI208V1K via STEVAL-MKIGIBV2 (conected those both togheter) , with Nucleo-F401RE. I conected pins as it is shown below
F401RE-> MKIGIBV2
MOSI (PB3 -> SDA
MISO -> SDO
SCK -> SCL
PWM/D6 -> CS
3v3 -> VDD
GND- >GND
I want to use SPI 4 wire interface but immediately after connecting nucleo to the PC I lost conection to the board and led LD1 starts blinking red. Do I need to connect some other pins as well with a board? Do I need to use some pull up resistors to the pins?

Hi @Konrad Długozima ,
You need to connect also VDDIO to 3V3.
