I have an unused Odroid U2 sitting around which I could provide for running a Community-Hosted CI. It runs Ubuntu 18.04, but is a bit older already. Hence the not to powerful specs: 1.7Ghz Quad core ARM Cortex-A9, 2GB RAM. I don't know if those specs would be sufficient, but since we had a Rasberry PI as CI I guess so.
What would I need to do to set up this machine as a Community-Hosted CI? I must confess I never compiled my own toolchain before, so some pointer to a README or such would be very helpful.
Thanks in advance,
