Bug with STM32L476 PLL source?

Posted on September 25, 2017 at 03:42

Hi All,

I have been experimenting with my

http://www.st.com/en/evaluation-tools/nucleo-l476rg.html

I have generated some code with CubeMX for SW4STM32 and I am getting some problems with the code, ending up in an Error Handler sometimes (in main):

void _Error_Handler(char * file, int line)

{

  /* USER CODE BEGIN Error_Handler_Debug */

  /* User can add his own implementation to report the HAL error return state */

  while(1)

  {

  }

  /* USER CODE END Error_Handler_Debug */

}

This happens when I do the following:

Use the main clock source for the PLL as HSI, and tick the option 'generate peripheral initialization as a pair of '.c/'h' files per peripheral', which I prefer to keep things tidy, in CubeMX.

If I use the MSI instead of the HSI, I don't get this problem.

I am attaching my project for your perusal. Is this a known bug? Or am I missing something?

Thanks!
