HAL_Delay infinite loop due to return 0 from HAL_GetTick

1

Hello,
I’m trying to make a simple blinky program using a stm32f3 Discovery board, but for some reason HAL_GetTick(); will return always 0 while calling HAL_Delay(20);

My platformio.ini looks like this:

[env:disco_f303vc]
platform = ststm32
board = disco_f303vc
framework = stm32cube
board_build.f_cpu = 72000000L
build_flags = -Wl,-u_printf_float
    -D HSE_VALUE=8000000UL

Code is here:

#include "stm32f3xx_hal.h"

static void SystemClock_Config(void);

#define LED_PIN12                              GPIO_PIN_12
#define LED_PIN8                               GPIO_PIN_8
#define LED_GPIO_PORT                          GPIOE
#define LED_GPIOE_CLK_ENABLE()                  __HAL_RCC_GPIOE_CLK_ENABLE()
#define LED_GPIOE_CLK_DISABLE()                  __HAL_RCC_GPIOE_CLK_DISABLE()

void LED_Init();

int main(void) {
  HAL_Init();
  LED_Init();
  SystemClock_Config();
  SystemCoreClockUpdate();  


  while (1)
  {
   /* USER CODE END WHILE */
   HAL_GPIO_TogglePin(LED_GPIO_PORT, LED_PIN12);
   HAL_Delay(20);
   HAL_GPIO_TogglePin(LED_GPIO_PORT, LED_PIN8);
   HAL_Delay(20);
  }
}

void LED_Init() {
  LED_GPIOE_CLK_ENABLE();
  GPIO_InitTypeDef GPIO_InitStruct;
  GPIO_InitStruct.Pin = LED_PIN8;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Pull = GPIO_PULLUP;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; //GPIO_SPEED_HIGH;
  HAL_GPIO_Init(LED_GPIO_PORT, &GPIO_InitStruct);
  HAL_GPIO_WritePin(LED_GPIO_PORT, LED_PIN8, GPIO_PIN_RESET);

  GPIO_InitStruct.Pin = LED_PIN12;
  GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
  GPIO_InitStruct.Pull = GPIO_PULLUP;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
  HAL_GPIO_Init(LED_GPIO_PORT, &GPIO_InitStruct);
  HAL_GPIO_WritePin(LED_GPIO_PORT, LED_PIN12, GPIO_PIN_RESET);
}

void Error_Handler(void)
{
  while(1)
  {
  }
}

static void SystemClock_Config(void)
{
  RCC_ClkInitTypeDef RCC_ClkInitStruct;
  RCC_OscInitTypeDef RCC_OscInitStruct;
  RCC_PeriphCLKInitTypeDef  RCC_PeriphClkInit;

  /* Enable HSE Oscillator and activate PLL with HSE as source */
  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
  RCC_OscInitStruct.HSEState = RCC_HSE_ON;
  RCC_OscInitStruct.HSEPredivValue = RCC_HSE_PREDIV_DIV1;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
  RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL9;
  if (HAL_RCC_OscConfig(&RCC_OscInitStruct)!= HAL_OK)
  {
    Error_Handler();
  }

  /* Configures the USB clock */
//  HAL_RCCEx_GetPeriphCLKConfig(&RCC_PeriphClkInit);
//  RCC_PeriphClkInit.USBClockSelection = RCC_USBCLKSOURCE_PLL_DIV1_5;
//  HAL_RCCEx_PeriphCLKConfig(&RCC_PeriphClkInit);


  /* Select PLL as system clock source and configure the HCLK, PCLK1 and PCLK2
     clocks dividers */
  RCC_ClkInitStruct.ClockType = (RCC_CLOCKTYPE_SYSCLK | RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2);
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  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_2)!= HAL_OK)
  {
    Error_Handler();
  }
}

void SysTick_Handler(void) {
  HAL_IncTick();
}

Is this code written in a .cpp or a .c file?

It is a .cpp file main.cpp.

Then all interrupt handlers are missing an extern "C", or they will never be called. The startup files is expecting a symbol name produced without name mangling.

Just say

extern "C" void SysTick_Handler(void) {
  HAL_IncTick();
}
