hello my frends
now i habe a new doubt!
i am traing to enable the DCMI in the STM32H743BGT6 whit the stmcubeIDE (in the cubeMX section)

and as you can see in the image above, the program does not let me enable the DCMI because its resources are used by the "PSSI" (which I NEVER enabled, and I imagine that it is an initial configuration by default)
(with fedora 41 on my PC) with this version:

and according to this tutorial: https://community.st.com/t5/stm32-mcus/how-to-configure-and-use-the-pssi-on-the-stm32h7/ta-p/49811

I should be able to disable the PSSI (which I don't want) in the section you see in the tutorial image
but I can't because that PSSI is NOT in that part, nor can I find where it is to DISABLE it anywhere in my  stmcubeIDE (as you can see in the first image I posted)
the question is: where will I be able to disable PSSI to enable DCMI?:crying_face:


Saludos!...

Hello @Maposaagsky 

I am not sure about the error message that occurred the conflict should not be with PSSI. could you please attach your IOC to investigate further.

Hello,

There is no PSSI interface on STM32H743 part number.

I opened your ioc file with the standalone CubeMx and as you can see there is no PSSI in the list.:
