Hi all, I have this old hardkernel odroid-u2 chugging away as a slow but reliable mediaserver. It's a few years old and uses a Debian Wheezy I downloaded from Hardkernel's site.
I now wanted to connect a two-bay USB/SATA adapter, but the odroid only sees one of the drives. Maybe it's something else, but probably it's just due to an old kernel / udev. So I dist-upgraded to jessy but got stuck halfway because the kernel is too old (3.0.57). Soon I found out that upgrading the kernel isn't as straightforward as on i386, first because of the (probably pretty simple) uboot loader, and secondly because there is a large variety of ARM SoC flavors, each of which requires its own kernel. So.... any tips? Am I even on the right path that the "invisibility" of one of the SATA drives is due to the old kernel /udev? I'm willing to build a new kernel for this thing. Last time I did that was probably literally almost 20 years ago. Also I'll probably need some sort of serial adapter, as the only way I currently communicate with this thing is via ssh; i.e., if the kernel won't boot I won't know why. There's plenty of recent pre-built images for various odroids, but not the (obsolete) u2. Any tips?
