I am new, I will admit it, but when a basic setup doesn’t work on a product, I am horribly discouraged.
I will outline the steps to break it. I am using the latest version as suggested via your popup (" Make sure you run at least Home Assistant Core 2021.1.5.")
Hook odroid-n2+ to computer and reload via USB and etcher (Steps here)
Initially boot system and setup starter user
reboot device
broken
Does it boot at all ?
Are there errors ?
What is displayed on the screen ?
I am going through the full steps again to outline them.
Write file on EMMC via etcher steps above
Boot

Reboot device using “Reboot Host”
Presented with the “Welcome to Home Assistant” with a couple of errors on hdmi audio codecs and axg sound card
Device is no longer accessible via web IP address
It looks like I had to complete the same thing others have complained about in the forum of overriding the healthy condition via command line:
jobs options --ignore-conditions healthy
After executing this, I am able to use the device after reboots. The question that still remains, is this a desired affect after a fresh image load? If so, what is not healthy as your wiki is lacking in any information regarding this as I am running things only as your builds allow without customization or changes.
It’s OUR wiki.
I’m a member here just as you are 
I’m glad that you found a solution.
The setup should not be unhealthy given that the odroid n2+ is officially supported (refer to home assistant blue).
Nick, you have my sentiments exactly. I purchased an N2+ with the basis that the major issues like this would have been weeded out. Though it stopped me for awhile, I eventually worked through it. I am still unsure if this is a known bug/issue or I should be sending in a bug report. It also doesn’t look like I am the first one to experience this issue with the Home Assistant.
I believe for some reason that escapes me me now [1] that balloob (our founder) use an n2 or n2+, which makes it even odder.
[1] some thread or issue or PR that I can’t now find.
I remember the same. It was in one of the forums with him saying to update to this. I remember asking how can you recommend this as the home assistant version at that time was an unreleased version. Never received a response. He recommended it here
https://community.home-assistant.io/t/on-hold-deprecating-home-assistant-supervised-on-generic-linux/194310/268
The ODroid N2 is beefier than a Pi and supports eMMC flash. It’s what I use myself and it’s super smooth.
I was thinking of switch to it from my pi4 due to SSD issues. Going to wait.
