Hello!
I have ported overt X-CUBE-CLKTRIM to the STM32L4R5ZI Nucleo board. Unfortunately the callback HAL_TIM_IC_CaptureCallback is not called. Which results in the HSI and MSI frequency measurements to be calculated as 0.
I have put a function generator to act as the HSI (X3) and I have converted the project for the nucleo board via the Target setting found in the project properties.

I've also added a function generator to act as the HSI at 8MHz.

So it looks as though the timer15 does not fire and is used to measure the HSI and MSI frequencies. However, Timer16 which is used for LSI does work.
