Generated code with RCC configuration failing at SystemClock_Config()

[repairman]

I have an STM32F7 which I have configured RCC for and am using HSE as a clock source. When using the debugger trying to step through the generated code, my project is failing at the SystemClock_Config(), specifically:

   /* Check the HSI ready flag */

   if (__HAL_RCC_GET_FLAG(RCC_FLAG_HSIRDY) == RESET)

   {

    return HAL_ERROR;

   }

  }

I’ve done everything in the configurator and there are no errors in the pin configuration section. I have not added any code yet to the generated code, so I am not sure what is causing this error. The RCC configuration does show warnings with Master Clock Output 2 and Audio Clock Input, since I am using SDMMC1 and they conflict, but I don’t think I need those so I’m not sure if they are the source of the issue.

Hello @repairman​ 

You said "I have configured RCC for and am using HSE as a clock source".

Are you sure you are using an external crystal?

  /* HSI is selected as System Clock Source */

  else

  {

   /* Check the HSI ready flag */

   if (__HAL_RCC_GET_FLAG(RCC_FLAG_HSIRDY) == RESET)

   {

    return HAL_ERROR;

   }

  }

--> this part of code is related to HSI usage.
