    Damaged Crystal pins STM32F407

    Hello friends,


    I have a few STM32F407ZET6 that do not work, and the reason for not working is getting stuck in the HSE Init function.

    I will change the capacitor and Crystal, but it will not be right
    when I change my Micro everything is fine

    Crystal = 8mhz
    capacitor= 20pf

    Where the CPU catches

    Code:
      if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
      {
        _Error_Handler(__FILE__, __LINE__);
      }

    I feel oscillator pins are damaged
    Is there a protective circuit for it?

    Re: Damaged oscillator pins

    Protection from what? Meteors? What damaged the micro originally?The oscillator circuit is going to be sensitive to anything you might attach there(additional capacitance/inductance).
