Dear All,

I am using STM32F030x6 for one of my projects ,

PLL not working with Mul 6 of Internal 8 MHZ oscillator.

PFA code .

Share your valuable advise to resolve the issue.

Thanks,

Utpal

Define 'not working'

The PLL doesn't lock? The frequency is unstable? You see the wrong frequency on MCO pin?

Doesn't seem to be using MUL 6

  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI;

  RCC_OscInitStruct.HSIState = RCC_HSI_ON;

  RCC_OscInitStruct.HSICalibrationValue = 16;

  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;

  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI;

  RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL12;

  RCC_OscInitStruct.PLL.PREDIV = RCC_PREDIV_DIV1;
