Clock confirmation in NUCLEO-F767ZI

[ak52]

Hello,

I was looking into this wiki tutorial on setting up a UDP echo server by @mƎALLEm , and the clock configuration caught my eye and wanted to confirm a few things.

1. On the nucleo board , the 8 MHz crystal (X3) is not soldered and the 8 MHz clock signal comes directly from the ST-Link MCU (U2) via SB149. I have checked this on a oscilloscope. 

But in the tutorial , in Section 2.1 Clock configuration Section , the screenshot shows the input frequency set to 16 MHz. As far i am aware this should be 8 , not 16 MHz. Can someone please confirm this?

The current STM32CubeMX version 6.15.0 generates 8 MHz HSE clock by default.

The screenprint shows 16 MHz which is wrong, but irrelevant here as the PLL Source Mux is switched to HSI clock, not HSE.

Thanks for the confirmation
