PC Engines ALIX
Overview
The ALIX family of small, energy efficient, single-board-computers from manufacturer PC Engines are available in several variants within four "series", all of which use the AMD Geode CPU (either LX700 or LX800) and have an on-board Compact Flash (CF) card socket for storage:
- ALIX1
- A miniITX board with 1 LAN connector and a VGA display output
- ALIX2
- A 6"x6" board with 2 or 3 LAN connectors, no VGA, an RS-232 console connector and optional USB connectors
- ALIX3
- A 100x160mm board with 1 LAN connector and an optional VGA display output
- ALIX6
- A 6"x6" board with 2 LAN connectors, intended for mobile telephony integration
Of these, the ALIX2 series is generally preferred for LEAF usage, mainly because of the multiple LAN connectors. In particular, the 2D3 and 2D13 variants are widely used for Bering-uClibc 4.x and perform well.
The following probably only applies to boards in the ALIX2 series.
Bering-uClibc 4.x Disk Image Selection
The ALIX2 boards have an RS-232 console connector and no VGA display output so the recommended Bering-uClibc 4.x disk Image is Bering-uClibc_4.VERSION_geode_syslinux_ser.tar.gz
which is tailored for serial consoles.
Hardware / Driver Details
- The network controller chips are VIA Rhine™ III VT6105M Fast Ethernet Controller (one per LAN port) and need kernel Module
via-rhine.ko
- The first network interface (eth0) supports passive Power-over-Ethernet (not standard 802.3af) and PXE boot.
- The AMD CS5536 "I/O Companion" chip implements the following functions:
- IDE disk interface to the Compact Flash card, which needs kernel Module
pata-amd.ko
. - RS-232 interface. Support for this is built into the Bering-uClibc 4.x kernel so no Module is required.
- I2C interface via the NatSemi SCx200 ACCESS.bus which needs kernel Module
scx200_acb.ko
(which in turn relies oni2c-core.ko
).- This is often used in conjunction with the hardware temperature monitoring chip, an LM86 which needs kernel Module
lm90.ko
(which in turn relies onhwmon.ko
).
- This is often used in conjunction with the hardware temperature monitoring chip, an LM86 which needs kernel Module
- IDE disk interface to the Compact Flash card, which needs kernel Module
Installation Notes
Serial Console
As shipped from the factory, the serial console on the ALIX2 series boards is configured for 38400 baud, 8N1, no flow control. Currently (Bering-uClibc 4.0-beta3) the _ser disk image is configured for 19200 baud (because some users have reported problems with Serial <-> USB adaptors when running at 38400 baud).
These need to be aligned and need to match the setting of the terminal emulator being used. Either:
- Change the ALIX2 baud setting to 19200 (press S during the power-on memory test for the setup menu).
- Change 19200 to 38400 in file
syslinux/syslinux.cfg
and also in fileetc/inittab
which is embedded within fileconfigdb.lrp
