Good morning everyone!

On my board with Colibri VF50 I use CAN1 interface (55 and 63 pins).

I enabled:

CONFIG_CAN
CONFIG_CAN_RAW
CONFIG_CAN_BCM
CONFIG_CAN_FLEXCAN

in kernel config file.

And added

&can1 {
       status = "okay";
};

in the arch/arm/boot/dts/vf-colibri-eval-v3.dtsi file.

But i can`t understand how check that the CAN1 interface is working.

Have a look on the relevant article on the developer website.

Please note the need of a CAN transceiver.

What carrier board are you using? The Evaluation Board v3.2 allows to access the CAN transceiver through JP4/5. You can connect the transceiver side directly to SO-DIMM 55/63 using jumper cables.
