Debian has a "network-console" variant of the Debian installer
(https://d-i.debian.org/daily-images/armhf/daily/network-console/),
which allows using the installer over an ssh session. This makes
installations without a "local" console device (i.e. HDMI or
serial console) possible, but usually just connecting a serial
console cable is the easier option.
According to the datasheet, the Odroid HC1 uses an Exynos-5422
SoC, which I am not familiar with. The mainline kernel appears
to have general support for this SoC but it appears to lack a
device-tree for the HC1 board.
Another thing that would need checking out is whether the system
can boot with only free software. I may well be remembering that
wrongly, but I believe to have read somewhere that at least some
older Exynos SoCs couldn't be booted with only free software as
they required a signed proprietary first-stage loader, which
would make providing offical Debian installer SD card images for
this platform impossible due to the necessity of including
non-free code.
