Wake on Lan for Alta

Hi, I’ve recently purchased an Alta AML-A311D-CC for use as a Kodi media player. So far I have successfully installed and configured NixOS, Kodi and am booting off the latest firmware. Everything is functioning well, with the last issue to solve being shutdown/suspend. It seems so far that ‘shutdown -h now’ won’t permanently poweroff the board without rebooting which is OK as long as I can suspend and resume the system. I’m using an OS config for WOL that works on my other systems and have set kernel parameters ‘meson_gxl.enable_wol=1’ in systemd-boot. No luck so far resuming from suspend either through magic packets or cec signals from the TV. Ideally I’d like to have both working. Any tips on what to try next?
