Hello I am running home assistant on a container on jetson nano.
I am trying to run a serial node as I have a device that is using simple serial commandes I am trying to use node-red-node-serialport 1.0.1 (node-red-node-serialport)
When I try to run the node red I get a error log like this

Welcome to Node-RED
===================
Hi there, the log you've shown does not have an error really. It is only telling you that the Raspberry Pi specific node doesn't work on anything other than a Pi.
Have you tried installing node-red-node-serialport from the pallet manager? Note that it will almost certainly require a build step and so you will need to have dev-tools installed.
OK, so firstly try removing the node-red-node-pi-gpio node to make sure that isn't causing problems. Also make sure that the user id that is running node-red has access to the serial ports. On most versions of Linux, I think if you add the user to the dialout group, that should work but do double check.
Also, since you are running node-red in a docker container, you might have to do some jiggery-pokery to permit the container to use the physical serial port (not sure if HA already sets this up - you will have to ask on the HA forums)
Here is how someone using docker would setup a container to access the physical serial port...
If that all seems too much, then ditch the HA Node-RED Addon version red and install node-red to the OS instead.
Well, as you can see, Node-RED is not reporting any errors. I would increase the logging level in settings.js to see if you can spot what is causing the restart.
If that doesn't show anything then I'm afraid that I think it is either a Docker or more likely, a home-assistant issue and you may need to ask on the HA forum unless someone else here knows. Personally I use neither HA nor Docker for Node-RED.
