[meta-freescale] Flexcan is not working on I.MX 6Q SABRE SD board

[Paventhan K]

Hi Daiane,
                   I have already enabled flexcan by applying a patch to imx6q-sabresd.dts file. I am able to get the flexcan driver up and configure it. I am not understanding why does the bus state goes off even when the imx6q sabresd board's can transreceiver(TJA 1040T) is connected to the vector can. It would be very helpful even if you tell me how I can go about debugging it. I have tried using a DSO to check if I can see the transmission signal on TX. But when I connect the probe to CAN_H and CAN_L  of the transreceiver I see nothing. I have also noticed that the "stby pin" of the transreceiver always remains high(3.5V). Will I have to apply any patch to somehow make it low and then run the transreceiver in normal mode instead of standby mode?

With regards,
Paventhan.K
