CUBE-IDE / CubeMX Bug? Cannot setup clock for STM32N6 processor

Hello,

Does anyone know how to setup the clock source for the N657 processor?  I want to use an oscillator for the HS clock input and setup HSE = Bypass clock source...

using Bypass clock it should only use PH0 (clock in) and free up the PH1 pin (clock out).  But it seems the IDE / cubeMx always wants to use both pins regardless of the clock configuration.

am I missing something or is this a bug?

thanks, Matt

Hi,

maybe small inaccuracy in Cube ,or N6 just dont switch off osz-out . (read in rm or errata...what it should do)

But it has enough other pins, so not  free up the PH1 pin is nothing to worry about.
