The SystemClock_Config function which is generated by CubeMX will disable Systick Timer. If you select LL Driver for RCC.
After calling SystemClock_Config the SysTick->CTRL is set from 0x7 to 0x5 in the Package L4.13.1 and to 0x01 using package L4.14.1 (even worser!). Systimer Interrupt is then disabled!
If you use HAL driver for RCC, SysTick->CTRL remain at 0x7 and it is ok.
Use L4R9I-EVAL Board, CubeMX V5.1 /V5.2, Package L4.1.13 /L4.1.14
Is there a bug in LL Driver?
