HI

    I am debugging can bus on sabresd platform.But CAN bus cann't work normally on sabresd platform.

   I cann't probe the waveform from the CAN0_TX.

  Firstly i add the pin in board_mx6q_sabresd.h:

 

   MX6Q_PAD_GPIO_7__CAN1_TXCAN,
   MX6Q_PAD_GPIO_8__CAN1_RXCAN,

  Secondly ,I follow the steps below

   dmesg | grep can

    ip link set can0 up type can bitrate 125000

      ifconfig can0 up

      ifconfig can0

      cansend can0 -i0x100 11 22 33 44

    

     But i cann't still probe the waveform from the CAN0_TX

     The picture is as follows
