Hi! I'm running Arch Linux on my main computer and on a Raspberry Pi before.
Working for VIA, I have a lot of ARM SoC lying around, and hacked one of them up to run Arch.
The VIA Springboard is a Cortex-A9 800MHz SoC with 4Gb onboard eMMC, and 1Gb RAM. I have written up all the steps in a blogpost. It's very preliminary, but it does run, been able to install XFCE and all that.
Outstanding issues include bringing the kernel up to date, (the current one is back at 3.0.8), and there might be issues with the graphics, but none of them feels insurmountable.
There's a lot of parts to play with. The CPU should be good for 1000MHz originally (not sure why it's underclocked to 800, or whether I got something wrong). There's supposed to be hardware media playback support (albeit might be binary only). Has 8xGPIO, some other engineers here are doing a project (on Android) using the GPIO pins to control sprinkler, light, fan, and so on in an indoor garden....
Would love to hear what do you think!
