Embedded  Platform

LAB-8902 embedded platform is a new low power high-performance embedded platform made by China North Industry Control Group (NORCO Group),  This platform consists of touch Screen supported display and motherboard with a compact enclosure. The motherboard is based on [email protected] D510 processor+ ICH8M chipset, utilizingthe a Core Duo processor (1.66 GHz Main Frequency, L2 Cache: 512KB*2) with CPU, North Bridge and GPU integrated into one chip. The display is the LCD of10.1″LVDS.  LAB-8902 embedded platform is the perfect embodiment of the embedded system, with rich interfaces including 1*JTAG(XDP)/1*8 bit GPIO ports/1*LPC(SMBus)/1*PCI/1*PCI-E/1*MINI PCIE/1*PC104/2*COM and 8*USB2.0 ports. All the ports are of flexible expansibility and students are able to conduct various experiments and developments through this platform, which can facilitate their hardware design & analysis and and improving their capability on software programming. LAB-8902 embedded platform provides a display of 1*10.1″ LVDS and 1*VGA port.Its VGA+LVDS dual independent display can facilitate the operation.

Meego Installation and Configuration

In our project, we used Meego system image: meego-tablet-ia32-pinetrail-1.2.0.90.0.20110517.1.img downloaded from Meego repository, and followed the offical Meego installation instruction for Viewsonic tablet (   http://software.intel.com/zh-cn/articles/viewsonic_tablet_meego_installation/).  After installation, I immediately found out that Meego Tablet 1.2 OS does not support the touch screen function of this platform ( it seems no driver has been developed for it). During the multiple installation trials, mouse icon were showing up in multiple cases, which made me think that there must be a mouse driver developed in Meego Tablet 1.2 that the  Lab-8092 detected. Based on previous development experience using emulator on PC, there must be a configuration file somewhere that I can change and make it to work for this platform. Thus I started patiently searching related .conf file in /etc. My approach seems right, and I found the file and was able to do the following configuration
To Change Configuration to allow Meego Tablet to use Mouse
  • Gedit the file at /etc/sysconfig/uxlaunch
  • Comment out (Add “#”) the last line of code: xopts = -nocursor

No with this change, I got Meego Tablet 1.2 running on my  LAB-8902 embedded platform box, much smooth and faster than the Meego emulator running in Meego SDK, and very convenient for the testing.
