Where to apply interim patches?

[Andrei Chichak]

If I find a bug in CubeIDE/CubeMX's code generation (like not turning on power to SDMMC), is there somewhere on my system that I can alter the boiler-plate code that is used to generate the project until the correction comes out in a future release?

Thanks,

Andrei (from The Great White North)

You can define a post-generation command (script).

I see that there is an "After Code Generation" box in Project Manager/User Actions.

Any hints as to how to use it? sed scripts? awk? Is there any documentation to follow? ST videos?
