Hello,

we discovered why is not working. If you are using _*linux-imx*_ the 
problem is on board-mx6q_sabrelite.c. This file is not ready to work 
with TJA1040 transceiver. However, after reading the datasheet we found  
the solution . Change this line :

https://github.com/imx6-dongle/linux-imx/blob/imx_3.0.35_1.1.0-hdmidongle/arch/arm/mach-mx6/board-mx6q_sabrelite.c?source=cc#L754

to

if  (!enable)  

bitbake and that's all. It's working now on my sabre lite with socketcan.

Regards
