Hello ,

I designe my project using STM32F103RBT6 with 8 Mhz external crystal , and im using STM32CubeMX  4.21 .when i select HSE in RCC i have problem. when i debug the program , i have problem here:

RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE;

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

but when using HSI all things fine,

what's the problem and How can i fix it?

Hi

• You are using a custom board or an ST board? Using STM32F103RB nucleo I am not able to see you issue.
• Please refer to

  http://www.st.com/content/ccc/resource/technical/document/application_note/6c/a3/24/49/a5/d4/4a/db/CD00164pdf/files/CD00164pdf/jcr:content/translations/en.CD00164pdf

  you find some Recommended PCB routing guidelines.

Hello,

Im using

STM32F103RB nucleo Board . i think there is something wrong in stm32cubeMX software , here i the code that it generate :

void SystemClock_Config(void)

{

RCC_OscInitTypeDef RCC_OscInitStruct;

RCC_ClkInitTypeDef RCC_ClkInitStruct;

/**Initializes the CPU, AHB and APB busses clocks

*/ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_NONE; if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { _Error_Handler(__FILE__, __LINE__); }

/**Initializes the CPU, AHB and APB busses clocks

*/ RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2; RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_HSE; RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1; RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV2; RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1;

if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK)

{ _Error_Handler(__FILE__, __LINE__); }

/**Configure the Systick interrupt time

*/ HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq()/1000);

/**Configure the Systick

*/ HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);

/* SysTick_IRQn interrupt configuration */

HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);}

This code doesn't work , but when i use HSI it works great.

Is there something wrong in generated code?
