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 user space. This work is done. I booted an Openmoko user space. The way to do it on your own is described below.

Working

• USB-Ethernet
• Framebuffer console
• Xfbdev
• Wifi
• Touchscreen

Should work, but not tested yet

• Phonecalls ( >_< )

Not fixed yet

• ALSA ( --> no mplayer -.- )

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 Neo Freerunner).
  • First partition: vfat
  • Second partition: ext2 (root)
• mount it and extract http://ftp.o2s.ch/pub/openmoko/images/shr-full-eglibc-ipk--20091106-htcdream.rootfs.tar.bz2 to it.

Use internal memory

Start into fastboot mode

wget http://ftp.o2s.ch/pub/openmoko/images/shr-fso-console-image-eglibc-ipk--20091106-htcdream.rootfs.yaffs2 -O system.yaffs2
fastboot flash system system.yaffs2

Always get a 403: Forbidden. File seems to be there, but Iam not able to download it. <-- Fixed it (leviathan)

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

Using precompiled image

Download an kernel image from:

• http://ftp.o2s.ch/pub/openmoko/kernel/
• ftp://ftp.o2s.ch/pub/openmoko/kernel/

Select -htcdream-fastboot_sd.bin for SD-card booting or -htcdream-fastboot_mtd.bin for booting from internal flash.

Rename it to openmoko-boot.img (to keep consistent with the howto ;) )

Building new kernel

Use the kernel from the replicants. Fetch the kernel sourcecode from http://gitorious.org/replicant/gnulinuxkernel And configure it as you whish.

export HACK_DIR=`pwd`
git clone git://gitorious.org/replicant/gnulinuxkernel.git
cd gnulinuxkernel
git checkout -b leviathan
cp arch/arm/configs/openmoko .config
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-msm /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

For SD-card rootfs

mkbootimg --cmdline "console=tty0 no_console_suspend=1 root=/dev/mmcblk0p2 rootdelay=2 fbcon=rotate:1" \
--kernel $HACK_DIR/gnulinuxkernel/arch/arm/boot/zImage \
--ramdisk ./newramdisk.cpio.gz -o openmoko-boot.img

For internal rootfs

mkbootimg --cmdline "console=tty0 no_console_suspend=1 root=/dev/mtdblock5 rootfstype=yaffs2 rootdelay=2 fbcon=rotate:1 rw" \
--kernel $HACK_DIR/gnulinuxkernel/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 the phone

fastboot reboot

WLAN

Firmware

mkdir firmware
cd firmware
wget http://ftp.o2s.ch/pub/openmoko/firmware-wl12xx/wl1251-fw.bin
wget http://ftp.o2s.ch/pub/openmoko/firmware-wl12xx/wl1251-nvs.bin
scp * root@192.168.0.202:/lib/firmware/

Driver

Install package

wget http://ftp.o2s.ch/pub/openmoko/packages/compat-wireless-msmwifi_2009-10-28-.4_htcdream.ipk
scp compat-wireless-msmwifi_2009-10-28-.4_htcdream.ipk root@192.168.0.202:~
ssh root@192.168.0.202
<enter>
opkg install compat-wireless-msmwifi_2009-10-28-.4_htcdream.ipk

Compiling

Download http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2 (broken) I think now http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-old.tar.bz2 Unpack it. Change into the folder.

make ARCH=arm CROSS_COMPILE=/usr/local/openmoko/arm/arm-angstrom-linux-gnueabi/bin/ KLIB=$HACK_DIR/gnulinuxkernel KLIB_BUILD=$HACK_DIR/gnulinuxkernel "$@"

Change up

cd ..

Run following script

#!/bin/sh
compat=compat-wireless-2009-09-30/
mkdir modules/
for i in $compat/net/mac80211/mac80211.ko \
           $compat/net/wireless/cfg80211.ko \
           $compat/net/wireless/lib80211.ko \
           $compat/net/wireless/lib80211_crypt_wep.ko \
           $compat/net/wireless/lib80211_crypt_ccmp.ko \
           $compat/net/wireless/lib80211_crypt_tkip.ko \
           $compat/drivers/net/wireless/wl12xx/wl1251_sdio.ko \
           $compat/net/rfkill/rfkill_backport.ko \
           $compat/drivers/net/wireless/wl12xx/wl1251.ko; do
           cp $i modules/
done

Copy it onto your device

scp -r modules root@192.168.0.202:~

Connect to your device and start the networking:

insmod rfkill_backport.ko
insmod cfg80211.ko
insmod mac80211.ko
insmod lib80211.ko
insmod lib80211_crypt_tkip.ko
insmod lib80211_crypt_wep.ko
insmod lib80211_crypt_ccmp.ko
insmod wl1251.ko
insmod wl1251_sdio.ko
