[bug report] STM32CubeMX - RCC configuration for STM32F427

Hi Everybody

Developing code for STM32F427 I decided to use CubeMX. It was not the first time when I found the tool useful to start the project but the first time when I noticed a problem with the output configuration files, especially with RCC configuration.

Please find the following code into your main.c file:

  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI | RCC_OSCILLATORTYPE_HSE;

  RCC_OscInitStruct.HSEState = RCC_HSE_ON;

  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;

  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;

  RCC_OscInitStruct.PLL.PLLM = 8;

  RCC_OscInitStruct.PLL.PLLN = 180;

  RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2;

  RCC_OscInitStruct.PLL.PLLQ = 3;

  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)

  {

    Error_Handler();

  }

The function HAL_RCC_OscConfig returns with HAL_ERROR.

To run the program properly I had to remove RCC_OSCILLATORTYPE_HSI from the first line of the code above.That was the only modification. No more changes were made.

IDE: TrueSTUDIO

MCU and firmware package:

Is this a bug, or I did something wrong?
