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

I cannot enable DCMI for STM32H753ZIT in STM32CubeMX version 6.15.0.

 

I'd assume DCMI can be indeed used and that this is just a bug on CubeMX's part, but I'd like to verify before I do any orders.

Sometimes (especially when it comes to boards and not bare MCUs/MPUs) , some peripherals can be used simultaneously but require more advanced configurations, which CubeMx has yet to support. (At least from my experience)

Now would you believe me if I told you that I slept and woke up to the DCMI option available now?

I think what I did was try to generate code so that STM32CubeMX would download the MCU series package (e.g. STM32CubeH7) like the related thread vaguely mentioned. I then retried configuring the MCU, but the DCMI option was still grayed out. I restarted STM32CubeMX, still the same thing. I guess I didn't try *restarting* my entire computer, but I did that for virtual machine reasons and I guess now DCMI is working fine.

Glad I'm the person that's finally documenting this wacky behavior.
