Hello everybody,

I'm trying to test FlexCAN on Sabrelite imx6 board without success. Those are the steps followed :

1) Comprobed that linux-imx has CAN drivers enable
2) Added on the image the packages:canutils,libsocketcan and iproute2
3) Tested the Flex can with canconfig and cantest.

Everything seems ok, even I can see transmitted frames incremented. However there's not singnal on the oscilloscope.

I don't now why is not working. Any ideas or suggestions?

Thank you!

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
