Question

BUG: 3 different clocks labeled PLLI2SCLK in CubeMX

In the clock tool picture below, no less than 3 separate and different clocks are labeled PLLI2SCLK.

So, which one is input to MCO2 source mux?

Also, calculated clock values should be shown on arcs!

ST, Please confirm you understand and reproduced the problems and have filed one or two bug reports...

IOC attached.
