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 Intel@Atom 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 is excellent device for being used to conduct various experiments and developments, which can facilitate the hardware design & analysis. 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- downloaded from Meego repository, and followed the offical Meego installation instruction for Viewsonic tablet (   /zh-cn/articles/viewsonic_tablet_meego_installation/):

Required Software

1. Meego Tablet img image: meego-tablet-ia32-pinetrail- (download from here
2. Kernel patch: kernel-adaptation-pinetrail- from here
3. Patch file:ath3k-1.fw (download from here )
4. USB Bootable burning tool (download from here

Installation Procedure 

  • Install Windows PC, run Win32DiskImager.exe,and make a bootable USB stick using meego-tablet-ia32-pinetrail-。

  • Insert USB bootable stick to a USB port,power on and press Delete to start  the BIOS SETUP。 Go to Boot->Hard Disk Drivers->1st Drive, and change default hard disk book from SATA to USB. Press F10 to save and reboot.

  • Power on the system, and select Installation Only option at Meego installation menu. Follow the step-by-step to install. If there are no enough disk volume, you can select "Remove all partitions on selected drives and create default layout" in partition option。

  • After installation is complete, reboot and change 1st Drive back to SATA in BIOS Setup。

  • After Meego tablet 1.2 OS  is running,Enter terminal mode by pressing Ctrl+Alt+F1)。Use root privilege (default password is meego), and copy kernel-

adaptation-pinetrail- and ath3k-1.fw  file from USB stick into  /root, and update the kernel image by following command:

  • rpm -ivh --force  /root/kernel-adaptation-pinetrail-

  • Copy ath3k-1.fw file into /lib/firware, and then run the sync command: sync

  • Reboot the tablet, as tested, all speaker,wifi,multi touch,and bluetooth function normally.

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

Now 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.
