STM32L452RET6 HardFault from HSE

Posted on July 10, 2018 at 11:14

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.

Perhaps your Flash settings (wait states) are not correct ?

I would try with a reduced core clock.

Look at the code that is actually faulting. Ideally outputting diagnostic information to USART or SWV

Try also clearing the structures when allocating from the stack

RCC_OscInitTypeDef RCC_OscInitStruct= {0};

RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

Isn't this one of the known CubeMX bugs ('does not set one of the PLL parameters')?

Sorry, If I am reducing core clock, the problem save0690X0000060Li6QAE.png

Posted on July 10, 2018 at 12:23

And please say me, How change Flash settings on the truth?

Posted on July 10, 2018 at 13:20

Not sure what you mean, I guess there is something lost in Google-translation.

If the problem persists even without PLL, it looks like a runtime problem (bug).

Perhaps a stack overflow.

You could try to debug the issue, or add telemetry (debug output) to your code.

If I connect System Clock Mux to PLLCLK, no problem. But if connecting to HSE, problem is save.

If you are clocking at 8 MHz I don't think the flash is an issue.

Device should start/run from 4 MHz MSI

You might want to enable HSE and feed to MCO (PA8) pin, and scope it there.

For oscillator source, consider HSE BYPASS mode.

Check HSE coming ready.

Check also define for HSE_VALUE in stm32xxxx_hal_conf.h

There have been issues with PLLM value being set up properly, but again, should drive directly from HSE
