OpenBSD/zaurus is an effort to make OpenBSD run on several PDAs of the
Sharp Zaurus family.
Initially targeted is the C3000/C3100/C3200 models which contain a 4GB CF
hard drive internally.

Shortly after Sharp unveiled its first Zaurus machines, some OpenBSD developers
started dreaming of running OpenBSD on it, to have the smallest possible
After the OpenBSD/cats was completed in order to benefit
from a good ARM development platform, work on the Zaurus hardware started in 2004.
Since the Zaurus is a fully capable machine, we no longer cross compile. All
builds of Zaurus are done on the Zaurus directly. (The shared "arm" packages are
nowadays built on the armish platform, because it is faster.)
Hardware support is mostly complete and quite stable.
The Zaurus boots multiuser, X11 runs, and device support is being
Most PCMCIA/CF devices work (such as wireless/ethernet cards), as well
as host USB, SD/MMC memory cards and the keyboard and touch screen are supported by X11.
Audio playback is working, and the machine is of course able to suspend
much like a regular laptop.
Even the processor performance mode can be adjusted with
apmd(8), just like on other platforms.
For a complete system component and device driver listing for this architecture, see intro(4/zaurus).
- Zaurus SL-C3000 (Spitz) / SL-C3100 (Borzoi) / SL-C3200 (Terrier)
- Intel PXA27x ARM cpu at 416MHz.
- 64MB of ram.
- com(4) standard and infrared serial ports.
- lcd(4) display panel, supporting wscons(4) console which supports X Windows.
- zts(4) touch screen acting as wsmouse(4) mouse controller.
- zkbd(4) native keyboard.
- pxapcic(4) PCMCIA slot, supporting most CF-sized pcmcia(4) cards (or PCMCIA form-factor ones, via an adapter).
- wd(4) on-board microdrive.
- ohci(4) USB controller supporting most usb(4) devices, or acting as a cdcef(4) 'ethernet' slave.
- pxammc(4) MMC/SD/SDIO controller.
- apm(4) power management and suspend.
- zaudio(4) audio.
Devices that can be connected:
- zrc(4) remote control.
- Most USB devices, see usb(4) for a list.
- Most PCMCIA devices (in a CF formfactor, or via a CF-PCMCIA adapter), see pcmcia(4).

Projects & bugs left to fix
- Repair pcmcia issues that are causing "white-out" problems with some devices.
- Fix the odd suspend crashing bugs and RTC skew.
- C860/C1000 support.
- Support the I2C GPIO controller (C3100 and C3200) using the
machine-independent i2c code.
- Internal flash memory support as a sd(4) device.
- Fix battery drain during suspend.
- Fix remaining issues in SDIO support.
