Hope this helps
Hi!
I successfully ran the installation on a NVIDIA Jetson Nano with my ValueCAN device. The device LED lights up when I plug it in, and can0 up brings the device up. But when I use candump any or candump can0, I cannot see any CAN data in the terminal window. I have a multi node setup where my RaspberryPi is showing all traffic correctly via candump via an MCP2515 from 2 other nodes.
When I try to send
sudo ip link set can0 up bitrate 500000
the response isRTNETLINK answers: Operation not supported.
It doesn't allow me to change the speed of the interface. I think this is what is stopping the CAN traffic from being shown.
I can use cansend and send data which is picked up by the other nodes (and displayed by the RaspberryPi candump) but the message data and ID is garbled - my hunch is potential mismatched bitrate is causing this.
Any help would be appreciated please - let me know if you need me to read something from the system and report back
