Intel Galileo ...

neues Spielzeug .. Intel Galileo (http://arduino.cc/en/ArduinoCertified/IntelGalileo)

Ein im Arduino Formfaktor gebautes kleines Pentium Board. Wie immer schaue ich mir immer die neuesten Boards an und bestell mir 1-2 Stück davon.

Basierend auf einer Intel Quark SOC X1000 ist das Teil ganz nett .. Es ist auf Arduino getrimmt und hat daher keine Features wie HDMI Anschluss ..

Auf dem Board läuft ein Linux system

welches im normalen Betrieb dafür sorgt das Programme welche im Arduino IDE für Galileo geschrieben werden gestartet werden nach dem upload. Das IDE ist die Version 1.5.3 - jedoch speziell mit x86 compiler.

Das look&feel des IDE ist wie bei anderen Ardiuno boards ..  Wenn man einen sketch hochlädt wird das binary file übertragen und als process in der linux busybox gestartet.

Binary sketch size: 49,106 bytes (of a 262,144 byte maximum) - 18% used

zugriff auf die Konsole erfolgt über ein RS232 Schnittstelle welche als 3,5mm Klinkenbuchse ausgeführt ist ..

Wie das Kabel gemacht wird sieht man auf https://communities.intel.com/message/208514#208514

mit 115200 N81 verbinden -> funktioniert ..

Das board hat auch noch eine Mini-PCIe Slot - dafür muss man aber ein volles (kein busybox) linux per SD Karte starten da die Treiber nicht im normalen Kernel drinnen sind.

Ist ein ganz interessantes Board - jedoch scheint es noch etwas buggy zu sein - da mir das teil schon zwei mal mit einer Kernel panic abgerauscht ist .. 

auch direkt beim booten ist etwas nicht ganz ok ..
