STM32 PLL Configuration Triggers WWDG Infinite Loop, PLL Config Problem CMSIS STM32F746-Disco, Win 10, CubeIDE 1.8.0, CMSIS-only (no HAL), C.I've decided to change the clock of my MCU from HSI 16MHz to full 216MHz with PLL. I've setup the correct values for PLL parameters, but whenever I actually switch system clock to PLL, the thing crashes (and doesn't crash if I don't).It's a full empty project, only register definitions from MCU-specific headers and m7 core. For now it's an empty project that only lights up an LED - if it gets there, that is.I change AHB, APB dividers, all is fine. As long as I'm on HSI, it still works ok. I configure PLL and make sure the values are set - debugger shows all correct values, I triple checked every single bit with pen and paper. Literally.I noticed that HAL activates PWR peripheral during clock setup, which I don't do. Description of PWR peripheral in the reference manual gives no reason to believe it has anything to do with it, but maybe I overlooked something.Here's the interesting part:void rcc_init(void) {
//enable
