Did CubeMX 6.7 break H7 Clock Configuration?

HHuyn.15 · ‎2022-11-29

Hi,

I have just updated to CubeMx 6.7 and now my stm32H755 nucleo board shows error while setting to 480MHz. I'm pretty sure that this board can run this fast before.

Did the new CubeMx break clock config feature for H7 devices?

There is also this crazy aliasing issue with the UI refresh while I move the mouse to select the option. Does anyone know how to get rid of this?

Thank you.

To get 480 MHz, go to the RCC parameters and check that the product revision is "V".

For some reason the default is "Y".

Then set the power regulator voltage scale to 0.

@Pavel A. Awesome! That tweak did the trick for the clock. Thank you.

Thanks for the heads up on the RCC setting bug!
