**DRIVE OS Version:** Provide DRIVE OS version. Example: 7.0.3

**Issue Description:** The СAN interfaces/devices(canX) are not visible in the system - I ran the following commands:

$ sudo modprobe can  
$ sudo modprobe can\_raw  
$ sudo modprobe mttcan  
$ sudo ip link set can0 up type can bitrate 500000 dbitrate 1000000 berr-reporting on fd on  
Cannot find device “can0”

but the interfaces canX are not present. This problem does not exist on the Orin board. How do I work with the CAN bus using DriveWorks SDK on Thor?

Thank you!

Dear @dmytro.syniuk ,  
We have not verified CAN testing on DW and DW CAN samples are removed from the package. May I know what is the use case details?  
Does [Nvidia DriveOS 7.0.3 SDK- MCU Queries - #28 by SivaRamaKrishnaNV](https://forums.developer.nvidia.com/t/nvidia-driveos-7-0-3-sdk-mcu-queries/351822/28) helps for CAN testing?

Hello [SivaRamaKrishnaNV](https://forums.developer.nvidia.com/u/sivaramakrishnanv),

I want to connect an external CAN sensor like a GPS or IMU and read data from them. Therefore, I need access to the CAN bus from a SoC. I want to use the [DriveWorks API](https://developer.nvidia.com/docs/drive/drive-os/7.0.3/public/drive-os-linux-sdk-api-ref/group __can__ group.html) (protocol=can.socket, device=can0)for this, but there are no interfaces/devices “canX” in the system(Linux), I can’t set them up.

Thank you!

Dear @dmytro.syniuk ,  
On DRIVE AGX Thor there is no CAN support in CCPLEX. So socket CAN does not work.
