  any software or feature.
• Gives developers capability and FREEDOM to easily
  create and deploy applications.

• Customized platform and limited applications.
• No way for developers to create applications

10
How can you help?
Its your phone make it the way you want it to be.

• Help with power management and other issues.
• Make some great applications for the phone.
• Bring in some great ideas.
• Help with fixing bugs.
• Test for bugs.

11
Installing OpenMoko SDK its easy

• Install Openembedded Prerequisites
• mkdir moko
• cd moko
• wget http//svn.nslu2-linux.org/svnroot/mokomake
  file/branches/OM-2007.2/Makefile
• make setup
• make openmoko-devel-image

12
What is OpenEmbedded?

• Successor of openZarus projects.
• Software framework to develop Linux distros for
  embedded devices.
• Consists of metadata for various architectures.
• Has bitbake recipes for many many packages.

13
Process of making images
14
Oh no another build tool Bitbake

• Handles cross-compilation and inter-package
  dependencies
• Supports running any number of tasks and not
  limiting to fetching sources, compiling and
  building.
• It is Linux distribution and architecture
  agnostic
• Provides inheritance mechanism to share metadata
  among packages.
• Supports embedded python code!

QEMU Emulator

• Can emulate most of the hardware.
• Does not support AGPS.
• Get through Mokomakefile make qemu
• Can even emulate for Windows!
• So, build applications and run them using QEMU

17
Lets move to the demo.

U-boot mode

• Remove all cables
• Press the power and the auxiliary button for 5
  seconds.
• Phone enters into u-boot mode.

Flashing OpenMoko

• Download pre-built images and dfu-util.
• Run dfu-util on host side.
• Put kernel, root file-system and uboot in the
  phone.

• wget r http//people.openmoko.org/mickey/images/
• wget http//buildhost.openmoko.org/tmp/deploy/imag
  es/dfu-util
• ./dfu-util --list
• ./dfu-util -a 1 -R -D uboot.bin replace
  uboot.bin with the exact filename
• ./dfu-util -a 3 -R -D ./uImage.bin
• ./dfu-util -a 5 -R -D ./openmoko-devel-image.rootf
