Openmoko on HTC-Dream

Revision as of 15:39, 26 July 2009

Introduction

HTC-Dream is a android based phone. Android is running on top of a linux kernel. So we have basically no work to do using this kernel to boot an Openmoko userspace. This work is done. I booted an Openmoko userspace. The way to do it on your own is described below.

Working

USB-Ethernet
Framebuffer console

Setup the rootfs

In this example setup I used a SD-Card as root partition.
In order to follow this guide format a SD-Card (just like installing Openmoko on NeoFreerunner).
- First partition: vfat
- Second partition: ext2 (root)
mount it and extract http://downloads.openmoko.org/distro/releases/Om2008.12/Om2008.12-om-gta02.rootfs.tar.gz to it

Bootloader

You need to install fastboot. In order to do this, you will have need to have "root" on the existing android device or already have a developer version of the bootloader installed.

Kernel

Building new kernel

Use 2.6.29 from android.git.kernel.org. 2.6.27 rebooted after a few minutes without any reason.

export HACK_DIR=`pwd`
git clone git://android.git.kernel.org/kernel/msm.git
wget http://wiki.openmoko.org/images/3/3b/Openmoko-htc-dream-kernel-config.txt
cp Openmoko-htc-dream-kernel-config.txt msm/.config
cd msm
make CROSS_COMPILE=/usr/local/openmoko/arm/arm-angstrom-linux-gnueabi/bin/ ARCH=arm
sudo make CROSS_COMPILE=/usr/local/openmoko/arm/arm-angstrom-linux-gnueabi/bin/ ARCH=arm modules_install
sudo mv /lib/modules/2.6-29-openmoko-htc-dream /mnt/foo/lib/modules/
sync
umount /mnt/foo

Building boot.img

mkdir $HACK_DIR/mk_boot_img
cd $HACK_DIR/mk_boot_img
wget http://wiki.openmoko.org/images/9/92/Mkbootimg.bin
wget http://wiki.openmoko.org/images/f/f6/Newramdisk.cpio.gz
mv Newramdisk.cpio.gz newramdisk.cpio.gz
sudo cp Mkbootimg.bin /usr/bin/mkbootimg
mkbootimg --cmdline "console=tty0 no_console_suspend=1 root=/dev/mmcblk0p2 rootdelay=2 fbcon=rotate:1" \
--kernel $HACK_DIR/msm/arch/arm/boot/zImage \
--ramdisk ./newramdisk.cpio.gz -o openmoko-boot.img

Flashing boot.img

Start into fastboot
execute

fastboot flash boot openmoko-boot.img

restart then handy

fastboot reboot
