Problems with using SPI and I2C together

Hi,

i am using a NUCLEO STM32L412 board and i want to use SPI and I2C together.

Every bus works for itself - this is OK.

But when i measure the signals, i get SPI clock signal on SDA and vice versa the SDA Signal on SPI SCK. I initialized with CubeMx.

Here my connections:

PA12 - SPI1 MOSI

PA11 - SPI MISO

PA5 - SPI SCK

PB6 - I2C SCL

PB6 - I2C SCL

Attached a scope image (SPI CLK = channel 2)
