STM32H7 dual core support

[MMedv]

Does ST publish a roadmap of features/enhancements for CubeIDE? I'd really like to know what is planned for STM32CubeIDE for the dual core H7 chips.

For example, in Project Manager->Project, there is a setting "Dual Core Boot Mode", but it is greyed out. When will this be available? I'd like my CM4 to do boot initialization (for example of the RCC) rather than the CM7, but it seems this is not possible to generate out of CubeIDE right now.

Hello!

We don't have a public roadmap of planned features that we publish anywhere. This specific feature is currently not on the roadmap.

@Markus GIRDLAND​ So essentially, if you plan on using an H7 dual core chip, you can't count on using CubeIDE/MX at all. Only in the very narrow way ST currently has it set up. That is a bummer because CubeIDE/MX is so helpful in getting your HW setup correct. That's almost enough to discourage me from using the chip in a new design.

According @Markus GIRDLAND​  maybe no automation at that time but some doc may help you I guess.

Is option bytes may help you ?

And 3.58 years later, "Dual Core Boot Mode" is still greyed out .... :(
