SPI3 does not work on stm32f405

[hacknus]

I'm trying to use the SPI3 bus (alongside SPI1 and SPI2, which both work fine), however the clock does not seem to be activated.

[dependencies.stm32f4xx-hal]
version = "0.17"
# git = "https://github.com/stm32-rs/stm32f4xx-hal"
features = ["rt", "stm32f405", "usb_fs","spi3"] # replace the model of your microcontroller here

// initialize SPI3 for FLASH MEMORY
let sclk_3 = gpioc.pc10.into_alternate().speed(Speed::VeryHigh);
let sdo_3 = gpioc.pc11.into_alternate().speed(Speed::VeryHigh);
let sdi_3 = gpioc.pc12.into_alternate().speed(Speed::VeryHigh);

let spi3 = dp
    .SPI3
    .spi((sclk_3, sdo_3, sdi_3), MODE_0, 10.kHz(), &clocks);
