STM32747I-DISCO locked in error handler

[AstraRB]

Hello 

I tried a blinky code which works with an other disco board I bought several months ago and it doesn't work with the new one. I tried it in debug mode and I'm stuck here.

void Error_Handler(void)
{
  /* USER CODE BEGIN Error_Handler_Debug */
  /* User can add his own implementation to report the HAL error return state */
  __disable_irq();
  while (1)
  {
  }
  /* USER CODE END Error_Handler_Debug */
}

I saw in the forums that can be the power supply choice but it's the good one here I think 

I know my code works but it doesn't with newer boards, I bought the newer boards 3 weeks ago. 

Do you know what's happening here ?

Regards
