Use TX2 CAN Bus

I’d like to use the CAN Bus from my TX2 on a ConnectTech Spacely carrier board. The can0 interface does not appear in the host or container environments when listing interfaces with ifconfig -a.

Is it possible to enable this interface within Balena?


Can you do modprobe can-dev in the hostOS?

Hi @chachi,

The kernel modules should be loaded automatically if you have a CAN node in device tree. So no need to do manual modprobe.

So the CAN node needs to be added in the device tree for this.

Cool, thanks for the explanation. Should I add an issue to the TX2 repository?

Hey @chachi,

Please open an issue on the TX2 repo.

We will have an internal discussion about activating CAN on the board.
