I've been very interested in using low cost ARM platforms for my test computers and Linux servers in my home and lab. So far I've got two Raspberry Pi 2 boards as well as a Hummingboard-i2ex from SolidRun. The Hummingboard-i2ex is especially useful for me since it has a PCI Express interface that I need to validate Titan (Figure 1).

I've never supported a KickStarter project before, but the C.H.I.P. project is a single core ARM board for $9. I thought that a Raspberry Pi was a steal for $35, but the C.H.I.P. is $26 cheaper and it includes flash (eMMC).

PCIe enumeration

Figure 1 doesn't look like much, does it? This simple output from lspci means that the PCI Express interface on the ECP5 is being enumerated on the host. Big step!
