Advanced users • Re: systemd service ran fine on CM4 doesn't work on CM5

While not solving your problem, can't you use the /dev/serial0 alias to remove the need to detect which platform you are on?

That's a good shout, I hadn't spotted that it was an alias. Is it guaranteed to exist and be correct?

It may also be worth adding the following to the [Unit] section of your systemd unit file:

Code:

[Unit]BindsTo=dev-serial0.deviceAfter=dev-serial0.device

This will ensure that the serial device is present/available before your service is started.

There's a good real-world example of this in /lib/systemd/system/serial-getty@.service

Ah I was definitely missing that, thanks again - this is one of those things that worked so I never went back to look at it...

I can't find if there's any way of saying it needs uinput, or if that would even need to be specified?
