I have a odroid xu4. and use archlinuxarm on it. it worked for a long time and basically I only used archlinux on it and it was great as I use archlinux on laptop too.
but I had a power loss. now my odroid shows a blue blinking led which I dont know if it is normal or even changed because I didnt check that before. but I I cant connect via ssh to it cause it doesn't get an ip. I have no hdmi monitor or keyboard to check what is happening.
I tried to install a clean archlinuxarm install and it had the same issue.
I thought my board was gone so I just on a whim installed ubuntu and it worked.
but when I tried archlinux again it didnt work.
so only ubuntu works but I really dont like ubuntu.
what is happening with arch that makes it not boot?
UPDATE:
because the forum doesnt allow me to answer (it say too old a post) I put it here.
I dont know that was wrong but with the Apr 21th version of ArchLinuxARM-odroid-xu3-latest it booted fine and I went back to archlinux.
it may be as the user said because of network name change of lan changing to enu1.
