New ALIX 2d3

Filed under: Hardware, UNIX & Linux — Tags: , , , — martin @ 6:44 pm

I received my first new ALIX of the type 2d3 today. Apparently, this is the successor to the 2c3 and brings no major changes but just minor modifications. According to PC Engines:

• Increase USB current limit.
• USB headers as build option.
• USB ports 3 and 4 on header (not tested).
• Change optional serial header J12 to COM2.
• Add LED and switch pins to I2C header.
• Populate buzzer driver circuit, add pins for use as GPIO.
• Add option for power in header J18.
• Some enhancements to reduce EMI.
• Add second POSCAP to ruggedize 3.3V rail for high power radio cards.

I have highlighted the most apparent changes in the photograph (click to enlarge).

Migration of the pre-installed disk from my development ALIX 2c3 went fine, although I had to resolve a problem with some nasty mis-feature where Debian tries to keep persistent ethernet device names by hard-coding the MAC addresses into some obscure udev configuration file. The system complained about the following network issue, although eth0, eth1 and eth2 showed up properly in the output of dmesg:

Configuring network interfaces…SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device

Deleting the /etc/udev/rules.d/z25_persistent-net.rules file and rebooting resolved the problem immediately.

I never could quite get the hang of devfs or udev anyway. Here’s yet another reason to hate them. 😀

  1. Ist in diesem Gehäuse eigentlich Platz und eine Einbauvorbereitung für eine 2,5″ Festplatte? Und sind die Stromversorgung und das Kühlkonzept dafür ausgelegt?

  2. Nein, nein. Weiß nicht. Und welches Kühlkonzept?

    Ich habe mir sagen lassen, daß die qualitativ angeblich besseren Systeme von Soekris recht zeitnah den Hitzetod sterben, wenn sie zusammen mit einer 2.5″-Platte ins (bei Soekris dafür vorbereitete) Gehäuse gebaut werden.
