Could not stop Cortex-M device!

Hi,

I've just soldered a second PCB with a STM32F429ZIT6. The first PCB runs perfectly, so the code seems correct.

I compile, and debug the code. The code is loaded correctly because there is any complain from Keil.

I start debug, but when I configure the clock, the system crash.

The code starts with:

int main(void)
{
        GPIO_InitTypeDef GPIO_InitStruct;

  /* MCU Configuration----------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* Configure the system clock */
  SystemClock_Config();

[...]

And when the syestem goes to SystemClock_Config

void SystemClock_Config(void)
{

  RCC_OscInitTypeDef RCC_OscInitStruct;
  RCC_ClkInitTypeDef RCC_ClkInitStruct;
  RCC_PeriphCLKInitTypeDef PeriphClkInitStruct;

  __HAL_RCC_PWR_CLK_ENABLE();

  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);

  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
  RCC_OscInitStruct.HSEState = RCC_HSE_ON;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
  RCC_OscInitStruct.PLL.PLLM = 8;
  RCC_OscInitStruct.PLL.PLLN = 336;
  RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2;
  RCC_OscInitStruct.PLL.PLLQ = 7;
  HAL_RCC_OscConfig(&RCC_OscInitStruct);

  RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
                              |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV4;
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV2;
  HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_5);

[...]

Then in HAL_RCC_ClockConfig:

HAL_StatusTypeDef HAL_RCC_ClockConfig(RCC_ClkInitTypeDef  *RCC_ClkInitStruct, uint32_t FLatency)
{
  uint32_t tickstart = 0U;

  /* Check the parameters */
  assert_param(IS_RCC_CLOCKTYPE(RCC_ClkInitStruct->ClockType));
  assert_param(IS_FLASH_LATENCY(FLatency));

  /* To correctly read data from FLASH memory, the number of wait states (LATENCY)
    must be correctly programmed according to the frequency of the CPU clock
    (HCLK) and the supply voltage of the device. */

  /* Increasing the number of wait states because of higher CPU frequency */
  if(FLatency > (FLASH->ACR & FLASH_ACR_LATENCY))
  {
    /* Program the new number of wait states to the LATENCY bits in the FLASH_ACR register */
    __HAL_FLASH_SET_LATENCY(FLatency);

    /* Check that the new number of wait states is taken into account to access the Flash
    memory by reading the FLASH_ACR register */
    if((FLASH->ACR & FLASH_ACR_LATENCY) != FLatency)
    {
      return HAL_ERROR;
    }
  }

  /*-------------------------- HCLK Configuration --------------------------*/
  if(((RCC_ClkInitStruct->ClockType) & RCC_CLOCKTYPE_HCLK) == RCC_CLOCKTYPE_HCLK)
  {
    assert_param(IS_RCC_HCLK(RCC_ClkInitStruct->AHBCLKDivider));
    MODIFY_REG(RCC->CFGR, RCC_CFGR_HPRE, RCC_ClkInitStruct->AHBCLKDivider);
  }

  /*------------------------- SYSCLK Configuration ---------------------------*/
  if(((RCC_ClkInitStruct->ClockType) & RCC_CLOCKTYPE_SYSCLK) == RCC_CLOCKTYPE_SYSCLK)
  {
    assert_param(IS_RCC_SYSCLKSOURCE(RCC_ClkInitStruct->SYSCLKSource));

    /* HSE is selected as System Clock Source */
    if(RCC_ClkInitStruct->SYSCLKSource == RCC_SYSCLKSOURCE_HSE)
    {
      /* Check the HSE ready flag */
      if(__HAL_RCC_GET_FLAG(RCC_FLAG_HSERDY) == RESET)
      {
        return HAL_ERROR;
      }
    }
    /* PLL is selected as System Clock Source */
    else if((RCC_ClkInitStruct->SYSCLKSource == RCC_SYSCLKSOURCE_PLLCLK)   ||
            (RCC_ClkInitStruct->SYSCLKSource == RCC_SYSCLKSOURCE_PLLRCLK))
    {
      /* Check the PLL ready flag */
      if(__HAL_RCC_GET_FLAG(RCC_FLAG_PLLRDY) == RESET)
      {
        return HAL_ERROR;
      }
    }
    /* 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;
      }
    }

    __HAL_RCC_SYSCLK_CONFIG(RCC_ClkInitStruct->SYSCLKSource);

[...]

Arrives in HAL_RCC_SYSCLK_CONFIG and crash!!!

You can see exactly the moment which it crashes.

I've reviewed the solders but I don't find the throuble. Can anybody help me?

Thanks in advance
