Can I slave STM32s off of a master STM32 crystal clock oscillator ?

[MikeDB]

I want to have one STM32F730 using a crystal on OSCIN and OSCOUT, and then slave 7 other STM32F730s to the same clock. But if I connect OSCIN of these other 7 to OSCOUT of processor 1 I assume it will load that pin with too much capacitance. I can't see a way of getting a buffered clock out at the crystal frequency fHSE to drive the other processors so do I have to add an external buffer ?

Look at the schematics for any of the Nucleo boards. They use one STM32 as a debugger with a crystal attached and feed the main STM32 clock in.

I don't remember the details, but they're all in the schematics.

Well not all Nucleo board it would seem, but eventually found one as you described. The MCO function isn't described in the STM32F730 datasheet but I found the details in another STM32 device. Thanks
