Hi folks,


I'm trying to initialise system clock to 168MHz without using cubemx generated function just to get better grasp of the RCC , PLL and clocks. So currently I'm trying to use HSE as source for PLL and PLL out as System core clock, right after setting the clock switch bits in RCC->CFGR, controller crashes.


Attached below is the function.
