这个是我的程序，采用CAN2口能发送数据，can分析接收的数据，如果用CAN分析仪向控制板发送数据，控制板的接收中断无法进入，这是怎么回事，和别人程序对照没有发现问题呢，请大神指导，
can的配置
如下void Init_CAN2(void)
{
    GPIO_InitTypeDef  GPIO_InitStructure;
    CAN_InitTypeDef        CAN_InitStructure;
    CAN_FilterInitTypeDef  CAN_FilterInitStructure;

    /* Configure CAN2 RX pin */
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
    GPIO_Init(GPIOB, &GPIO_InitStructure);
