Hi,
I’m trying to get FlexCAN driver to work in imx6q-sabre-sdb – develboard
without any success.
I have added FlexCAN driver as a module in kernel config as well as the other
CAN-devices/drivers needed (can,can-dev, can-raw).
Also I added to arch/arm/boot/dts/imx6q-sabresd.dts following lines:
----
&flexcan1{
status = "okay";
};

Check the pin mux for the device. You'll probably need something like this
to get it to work:
&flexcan1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_flexcan1_1>;
status = "okay";
};
After recompiling kernel and programming it to device, when I modprobe flexcan
– module nothing happens. It doesn’t print that flexcan is found and when I add
the other CAN-modules
and try to access CAN0(or CAN1) they claim that there is no such device. I’ve
worked with FlexCAN in imx537 so I’m somewhat familiar how to access it, but
problem is that it does
not show up at all.
Is there something else needed to do to get FlexCAN working with imx6q? I did
search the internet, but didn’t find anything else what should be done.
Yocto version is 1.7.1 and kernel version is linux-imx-rt-3.10.17.
