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;

GPIO_Init(GPIOB, &GPIO_InitStructure);

GPIO_PinRemapConfig(GPIO_Remap_CAN2, ENABLE);

//使能CAN时钟

RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN1 | RCC_APB1Periph_CAN2, ENABLE);

//CAN重置所有参数

CAN_DeInit(CAN2);

//CAN结构体重置

CAN_StructInit(&CAN_InitStructure);

CAN_InitStructure.CAN_Prescaler =9;//(pclk1/((1+13+2)*9)) = 36Mhz/16/9 = 250Kbits设定了一个时间单位的长度9

CAN_Init(CAN2, &CAN_InitStructure);
