Question
Using STM32CubeIDE in order to program SPI1 on STM32U585AII6Q with SW NSS. The relevant pins are not initialized and PinOut seems weird.
Trying to configure SPI1 with SW NSS on STM32U585AII6Q with STM32CubeIDE.
While generating the code, the relevant 4 pins are not initialized.
The PinOut looks like that. This grey shade seems suspicious to me.
