Cannot enable SPI1 on F427

[ReinhardD]

Hi,

I cannot enable SPI1 interface in CubeMX with STM32F427.

I only see the message "I2S1" must be disabled":

But I2S is not used in my project.

In Pinout view it is possible to select Pins PA4 to PA5 and PB5 for SPI1-sugnals without error messages.

Whats wrong here?

Hello @ReinhardD 

Can you share your .ioc file if possible to reproduce your issue and which CubeMX version do you use?

Thank you

I tried a complete new empty project, and it was the same: SPI1 was greyed out.

Then I closed CubeMX and started it as administrator: and it works

No idea, what is the difference, but I can go on now with my project.
