Where single stepping with STM32H7 code works?

LMI2
Lead

Some ARM/STM32H7 CPUs have a problem with single stepping through code. Which CPUs didn't have this problem? I have planned to use STM32H750 because it is now somewhat available, but I could swap.

Read the ARM chip identification.

The ones which were an issue were the STM32F746/756 parts (r0p1)
