Hiberation states supported by UP 4000 hardware
Hello, Can anyone tell me the hardward-supported sleep states on the UP 4000? We have been using the UP board in a project and 'cat /sys/power/mem_sleep' only has [s2idle]. My project could benefit a lot from having 'deep' and 'disk' available as hibernate states. I do not know if this is specific to distro, but I'm running Debian 11.
I am new enough to these boards/linux that any further info you want to share on stable hibernation with a quick wake up is also valuable to me, but I'm hoping someone can run 'cat /sys/power/mem_sleep' on an UP 4000 and let me know the options shown.
thank you.
