STM32WB55CE Pinout & Configuration Interface has SPI1 greyed out

[alexRossRBR]

Created a new project for the STM32WB55CE microcontroller and I am trying to configure the SPI1 using the Pinout & Configuration tool. However, SPI1 is greyed out with the message "I2S1 must be disabled". I tried looking for the I2S1 and I think it is implemented with the SAI1, but that is also disabled. 

Is this just a bug? Or am I missing a setting?

Hello @alexRossRBR and welcome to the ST Community :smiling_face_with_smiling_eyes:.

I've tested personally and it works perfectly for the 3 STM32WB55CE MCUs. (STM32WB55CEU6, STM32WB55CEU7 and STM32WB55CEU6TR) 

I'm using CubeMX 6.9.2 and CubeIDE 1.13.2. I suggest you use the last versions of each tools.

PS: you Can activate both I2S and SPI in the same Time (as you Can see in the screenshots).

Best Regards.

Strange I have:

STM32CubeMX

Version: 6.9.2-RC4
Build: 20230910-1412 (UTC)

STM32CubeID

Version: 1.13.2
Build: 18220_20230914_1601 (UTC)

Do you have this same behavior with all STM32WB boards.

Best Regards.

Well I guess I have good news. It looks to have fixed itself. Even in older projects the option of SPI1 is now available. The only thing that I can think of is that I restarted my computer (I restarted CubeIDE a few times before that with no luck, but restarting the whole computer I suspect helped).

I discovered that this issue occurs if I open a project using a different MCU (namely STM32H563IIK6) first and then open a project with the STM32WB55CE. The SPI option will remain greyed out until I restart STM32CubeIDE.
