[Bug report] CubeMX bad Clock/SysTick configuration using LL
Hi,Using STM32L082KZUx MCU with CubeMX 5.4.0 and Keil. Wanted to use 16MHz with LL on RCC library but having bad clock configuration, SysTick is maybe 10 time faster. If I change on RCC to HAL, when it works as it should - Systick gets to be correct...
