http://events.linuxfoundation.org/2010/linuxcon-japan/amano Porting MeeGo to Other Devices Date: 2:45pm, Monday, September 27th Location: Quarante C1 Topic: MeeGo Presentation: {Slides} This abstract explains how to port MeeGo another devices. MeeGo project provides the complete platform OS layer and is highly optimized for any devices. Handsets, Netbooks, In-Vehicle Infortainment(IVI), Connected TVs, and Media Phones. MeeGo supports both of x86(Atom) and ARM. It has already supported Atom based Netbooks and Nokia N900(Smartphone). My goal is be able to port it to some devices. For example, Nexus One, HTC Hero, Beagle Board, and Japanese smartphones(HT-03A, Xperia, HTC Desire etc). This challenge will try from now(14th May). So I'll report on this session. This presentation targets software developers who want to learn porting MeeGo and some devices users.

7. Step1: How to restore your devices
● Nexus One
● Unlock the bootloader via fastboot cmd.
– $ fastboot oem unlock
● Copying files to mtdblock from PC via
fastboot cmd.
– $ fastboot flash userdata userdata.img
– $ fastboot flash boot boot.img
– $ fastboot flash system system.img
– $ fastboot flash recovery recovery.img

8. Step2: Creating an image
● Boot from microSD
● mic2(0.17 or later). MeeGo Image Creator
●--format raw --arch armv7l
● Write a raw image to the microSD

9. Step2: Creating an image
● Android kernel 2.6.29
● Change the firmware path to “/etc/firmware”
● Start with mahimahi_config
● Use bcm4329.ko as the wifi driver

10. Step3: Boot
● fastboot
● Load zImage to devices
● ./fastboot -c 'init=/sbin/init rootwait
root=/dev/mmcblk0p1 rootfstype=ext3 rw'
boot zImage Loading zImage....
Mounting rootfs from
/dev/mmcblk0p1....
Executing /sbin/init...
zImage fastboot

11. Step4: Display X Window and the Desktop
● Handset UX(Direct UI)
● xorg-x11-fbdev, (xorg-x11-evdev)
● mesa-dri-swrast-driver
● Portrait default is refered of aava
● /etc/meegotouch/devices.conf
● Software rendering (Too slow)

12. Step5: Merge to the MeeGo kernel
● Working now!
● Merge to MeeGo v1.1
● Kernel 2.6.35
● ARM MSM is no supported
● [GIT PULL] ARM MSM update for 2.6.35
● No merge

13. Next step: Release
● microSD image and zImage
● Kickstart file
● MeeGo for NexusOne(MSMQSD) will
released(Snapshots)
09/27/10 13

14. Issues, In the future
● Hardware acceleration support(EGL)
● Peripheral support(Sensors, Multi-touch, H/W
buttons, Telephony stack)
● Complete replacement!
● Android => MeeGo :-)
● Boot from mtdblock partition
● Support any smartphones. HTC, SonyEricsson,
etc
