CAN STM32F105
使用标准库函数。硬件为STM32F105芯片，外部晶振8M，CAN收发器为TJA1050，CAN_RX-PB8，CAN_TX-PB9。
CAN初始化失败。
贴上初始化代码：
SystemInit();
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB,ENABLE);
RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO,ENABLE);
RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN1, ENABLE);
GPIO_PinRemapConfig(GPIO_Remap1_CAN1, ENABLE);
/* GPIOB */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO | RCC_APB2Periph_GPIOB, ENABLE);
//CAN1 TXD -> PB9
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_Init(GPIOB, &GPIO_InitStructure);
//CAN1 RXD -> PB8
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
GPIO_Init(GPIOB, &GPIO_InitStructure);
CAN_DeInit(CAN1);
CAN_Structinit(&CAN_InitStructure);

程序中没有定义STM32F10X_CL。自己计算得到的波特率为250K，可是以250K无法通信。
求大神帮忙看看程序有啥问题
