eudev not creating nodes

[OllieGitHub]

I know this is deprecated, but I figured I would give this a shot anyway!

I have already read over #60 and the linked issues without luck

I am trying to get eudev to work on an embedded system that previously used a very old udev version (107). So I am making quite a large jump in versions

Entered command ('udevadm trigger --action=add' results in same strace below)
echo "add" > /sys/devices/platform/serial8250.0/tty/ttyS1/uevent

strace output:

With the most egregious line being: can not stat() node '/dev/ttyS1' (No such file or directory)

Am I missing something obvious? Thank you in advance
