HI:
我正在调试imx6的CAN 总线，但是现在当我量CAN1_TX的时候总是没有数据
我的操作过程是这样的，
我首先在board-mx6q_sabresd.h里面定义了特殊功能引脚
如下： MX6Q_PAD_GPIO_7__CAN1_TXCAN,
MX6Q_PAD_GPIO_8__CAN1_RXCAN,
然后我运行了下面的几条命令
dmesg | grep can
ip link set can0 up type can bitrate 125000
ifconfig can0 up
ifconfig can0
cansend can0 -i0x100 11 22 33 44
我做完这些去测试CAN1_TX时候，用示波器总是量不到数据
附件的图片是我的操作 详细流程
也如下方所示
root@freescale /$ dmesg | grep can
vcan: Virtual CAN interface driver
