Hello, Help me please. I configuration STM32L452RET6 in the CUBEMX, how on the pictures. Then I build project in the Attolic and go to debuger and then when MCU is starting work, it go in the HardFault_Handler(void) through 1-5 seconds. Why? I can't find problem. Maybe anyone know?
Crystal clock is Abracon LLC ABM9- 8.000MHZ-10-D-1U-T.

I am cheking clock signal on the MCO pin and signal is very good.
I checkdefine for HSE_VALUE in stm32xxxx_hal_conf.h. It is 8 MHz.
If I stand crystal clock on the 16 MHz and AHB Prescaler = 2, board is working. But if I stand crystal clock on the 8 MHz, MCU go to
HardFault_Handler(void) on the Debagger mode. But if I disconnect Debugger, and reseting MCU. MCU work stably. Why? Do you know?

Read out the content of relevant RCC registers in case of problem and check/post.

Hi Anton,
In both configuration case, are you able to debug step by step your SystemClock_Config() function by placing a breakpoint at the beginning. Then step into HAL_RCC_OscConfig(&RCC_OscInitStruct) to troubleshoot the Hard Fault ?
In addition, what is your hardware? Is it a board that you designed yourself? Or a NucleoL452?
