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
Sadati.Danesh
,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.
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?
