Configuring the NUCLEO-L452RE via HAL using nothing but the default values for the board in STM32CUBEIDE and setting PA8 as the master clock output to monitor HSI16, the clock frequency at PA8 is 16MHz. When configuration is done via LL (Project Mana...

Yes, I am sure HAL HSITRIM is 0x40; I think what is happening is that the 0x40 is changed to a 0x0 byt the IDE. Only the displayed value is incorrect. HAL is ignoring the value in HSI Calibration Value; rather, it is programming this in SystemClock_C...

Thanks for the reply, waclawek.janIndeed, the values I wrote are accurate. I am reading them with a debugger. As you say, when I change HSITRIM, HSICAL also changes. However, I cannot change it to 0x40 because I get a pop up error notice saying that ...
