[BUG] DCMI disabled in absence of PSSI peripheral STM32H7 series

[max4]

Specific STM32H7 series MCUs have the DCMI peripheral greyed out in STM32CubeMX version 6.17.0.

See this image:

Hovering over the peripheral it displays "Not available: DCMI and PSSI are in exclusive choice"

I opened a few projects with different MCUs and checked whether the DCMI was greyed out:

​​STM32H723ZGIx - Working
STM32H725IEKx - Working
STM32H730ZBIx - Working
STM32H733ZGIx - Working
STM32H735IGKx - Working
STM32H742BITx - Not working
STM32H743XGHx - Not working
STM32H745BGTx - Not working
STM32H747XGHx - Not working
STM32H750IBTx - Not working
STM32H753Allx - Not working
STM32H755XIHx - Not working

The PSSI peripheral is notably absent from the list of available peripherals (correctly as per the datasheet) in STM32CubeMX for the parts where DCMI has been disabled.

This is clearly a bug in the mutually exclusive check in STM32CubeMX between the DCMI and PSSI, failing on the parts without the PSSI peripheral. 

See: 
STM32CubeMX 6.15.0 claims "DCMI and PSSI are in exclusive choice" for STM32H753ZITx (and others). | Community

Why the DCMI is disabled for the STM32H747 discovery board in the CUBE IDE? also when Touch GFX will be supported in the IDE? | Community

Hello ​@max4 

Have you tried to restart STM32CubeMX and retry to select DCMI peripheral,

From my side I can select DCMI :

Thanks Souhaib!

Restarting STM32CubeMX seems to have resolved my immediate issue but the bug still persists under certain situations.

To replicate the bug, open any STM32H7R7/7S7 or STM32H7R3/7R3 project prior to opening a project with the MCUs previously listed.

Kind Regards, Max
