PLLQ maximum frequency reported as 32MHz using STM32CubeMX v6.11.1

euanbrown · ‎2024-05-09

Somewhere between CubeMX 6.9 and 6.11 a bug has been introduced that reports the PLLQ can only be less than 33MHz.

It is not honouring the Voltage scale set in the RCC parameters.

I have set the voltage scale to "Scale 1" but it still reports the PLLQ to be limited to 32MHz which is actually "Scale 2"
