I've tried the latest and previous odroid-c2 bundles and have had no joy with either:
md5sum A*odroid*.gz
0a83b1b3f02c0be59446b3e7605466c0 ArchLinuxARM-odroid-c2-latest-old.tar.gz
1ee66f2d15718d80493588187aebb4b3 ArchLinuxARM-odroid-c2-latest.tar.gz
I'm happy my card writing setup is ok, as I've managed to get Arch on PI/PI3 fine.
I've also had Ubuntu on the odroid-c2 using the hard kernel image.
With Arch on the odroid C2 I just get the Blue light on solid, it never properly boots.
I'm using an SD Card rather than eMMC (32Gb Sandisk Ultra class 10/UHS-1).
The same card works with the Ubuntu image.
Does anybody have it working with an SD Card?
Thanks
Andrew
