Hello,

What does the NVIDIA Jetson Linux Driver Package Software Features document say?
NVIDIA Jetson Linux Driver Package Software Features, Release 32.6.1 | August 3, 2021

CAN on Jetson Nano Devices

A CAN controller is not available in Jetson Nano devices, but you can use an MCP251x chip (SPI to CAN interface), which works with the SPI interface on Jetson Nano

Thank you.

Just follow the document said to use an MCP251x chip (SPI to CAN interface), which works with the SPI interface on Jetson Nano.

Strangely, while I get emails to my work account from these forums, when I logged in, it said no account existed under that email…

Looking at the post from @Hodu - their USB-CAN interfaces are marked as being “cando” - looking at their website, they appear to have not bothered writing a proper socketcan driver for Linux, and instead offer some sort of proprietary SDK - CANdo - Simple USB to CAN Bus API

Such hardware might not play nice with a Jetson since their binary SDK is probably x86 only. Other USB-CAN converters (such as the CANable I mention, anything supported by the candlelight project at GitHub - candle-usb/candleLight_fw: gs_usb compatible firmware for candleLight, cantact and canable, EMS CPC-USB converters from USB/CAN Interface CPC-USB/ARM7 - EMS Dr. Thomas Wünsche, and a few others work with socketcan. I believe PCAN adapters will work too, but I haven’t personally used them.
