How can I check the revision of the m7 core without checking the registers?

How can I check the revision of the m7 core without checking the registers?

The revision r0p0 and r0p1 have a problem. When debugging  jump to a timer interrupt or debug sequence is bad.

So I would like to know how to check revision in advance when buying m7 core.

Look into the errata for given STM32 model.

Yes I also refer to errata. However, the revision of the cpu I am using is only visible to r0p1.

So I asked the question if I was wrong about checking revision.

I think I've posted a list of the cores used by various F7 and H7 parts here multiple times.

ST doesn't change the core used in each model once committed.

​omg... I am using stm32f746igt.

I have to change the my cpu.

Thank you. Have a nice day.
