如题：移植完成了，但是运行到：

int LCD_X_DisplayDriver(unsigned LayerIndex, unsigned Cmd, void * pData) {
  int r;
  (void) LayerIndex;
  (void) pData;
  
  switch (Cmd) {
  case LCD_X_INITCONTROLLER: {
    //
    // Called during the initialization process in order to set up the
    // display controller and put it into operation. If the display
    // controller is not initialized by any external routine this needs
    // to be adapted by the customer...
    //
    // ...
    Init_RA875();       
    return 0;           //到这里，退出后进硬件错误中断。
  }
  default:
    r = -1;
  }
  return r;
}

运行完   Init_RA875();       
            return 0; 进入：
void HardFault_Handler(void)
{
  /* Go to infinite loop when Hard Fault exception occurs */
  while (1)
  {
  }
}
