Unable to connect to CANUSB

 

I have a Raspberry Pi 4, which I would like to run my layout from. I have Ubuntu 22.04.5 LTS installed. I have JMRI 5.11.3 installed. I will be running on MERG CANBUS.

I've been creating my layout in simulated mode and decided to connect up to the hardware. I changed the properties to use CAN and saved, I get this error message.

After a bit of rooting around on the NET I found a command that produces the following

So it appears the ttyACM0 is being recognised.

Any suggestions?

Further to previous, this is the terminal output during startup.

Hello,

Have you added your user to the 'dialout' group? Typically this is a necessary step for running any software not as the root user that connects to a serial port on Linux.

Hi Noah.

No I haven't. Have been reading up and I have just got in and fired up.

I was wondering whether to load the PiOS/JMRI image that's available.

Cheers.

Neil

It's already on the Linux page.
