PITX-SP is a small Intel Atom board by Kontron.

I use it as a NAS system based on Openmediavault. Kontron currently only provides a Linux system based on kernel 2.6.38 . It took a while to get a fully functional board with a current kernel, because Kontron applied some changes to it:

  • support for Intel USB Client Controller
  • support for Intel EMDG backlight
  • support for the Kontron CPLD, which is mounted onboard
  • some changes to enable ACPI (suspend mode etc.)
  • support for GPIOs (via CPLD)
These changes are not part of any official kernel. So I had to apply and adapt all changes (beside the USB client controller as I don't need it) to it. Additionally I added the non-fuse exfat driver and the latest Intel e1000e driver. You can download the patchfile for kernel 3.16 and the debian package for kernel 3.18.5 here.
