Cross-Compiling Android Kernel – Samsung GalaxyS2

Das GalaxyS2 läuft ziemlich gut mit dem neuen nightly-builds von CM9 (Android 4.0.4) & den neusten Google-Apps & dem SiyahKernel.

Ich möchte hier kurz erklären, wie du einen Kernel für das Samsung S2 (CM9) auf Basis vom SiyahKernel kompilierst. :) 

 

1.) Installiere Linux + Cross-Compiler 

Als erstes solltest du Linux bereits installiert haben (z.B. Ubuntu, Debian …) ggf. einfach auf einen virtuellen PC z.B. via VirtualBox. Für Ubuntu gibt es bereits ab Werk GCC für ARM, bei Debian habe ich bisher folgende Paket-Quellen ( /etc/apt/sources.list ) mit aufgenommen und anschließend gcc-4.6-arm installiert, jedoch bisher nur mit Debian *sid* getestet.

deb http://www.emdebian.org/debian/ unstable main

Install:

sudo apt-get install build-essential git gcc-4.5-arm-linux-gnueabi wget libncurses5-dev

 

2.) Download der Quellen via github

Fork via github die Quellen welche du kompilieren möchtest und lade deine eigenen “Sources” herunter, um später ggf. “Pull Requests” zu stellen. Daher musst du bei den folgenden Befehlen “voku” durch deinen eigenen User-Namen bei github ersetzen.

 mkdir -p ~/sgs2/kernel/

cd ~/sgs2/kernel/

git clone https://github.com/voku/siyahkernel3

git clone https://github.com/voku/initramfs3

PS: “~” (tilde) = home-Verzeichnis -> info

Falls du nun einen anderen Cross-Compiler installiert hast als ich, musst du in der Datei (build_kernel.sh) die CROSS_COMPILE Variable anpassen. (whereis – locate the binary, source, and manual page files for a command)

cd ~/sgs2/kernel/siyahkernel3

./build_kernel.sh

 

Sobald der Kernel kompiliert wurde findest du folgende Datei “zImage”, welche wiederum der Kernel selber ist. ;)

 

PS: hier meine Version kompiliert mit gcc-4.6 & -Ofast & neuem Tweak-Script ->  http://samdroid.voku-online.de/index.php?action=list&dir=SGS2&order=name&srt=yes

 

Tipps: 

- CyanogenMod 9 Flashen -> AOSP 4.0.4 Cyanogen (mod) 9 Flash Anleitung

- keine Angst vor git -> man braucht meistens nur ein paar Befehle -> “git pull” & “git  push” & “git add –all” 

- git? -> http://rogerdudler.github.com/git-guide/index.de.html 

- Kernel-Config -> ~/sgs2/kernel/siyahkernel3/arch/arm/configs/siyah_defconfig 

- Tweak Skript ->  ~/sgs2/kernel/initramfs3/sbin/ext/thunderbolt.sh

- Makefile ->  ~/sgs2/kernel/siyahkernel3/Makefile

Google Chrome App für Android 4

Gerade bei Twitter gelesen: “Google veröffentlicht Chrome für Android“. Leider ist die neue Google Chrome App nur für Android 4.0 “Ice Cream Sandwich” und für bestimmte Länder verfügbar… aber da ich seit einigen Wochen ein Galaxy S2 mit CyanogenMod9 nutze, ist das kein Problem für mich. ;)

Screenshots von Android via shell

Wenn man auf seinem Android beispielsweise einen Kernel mit 24bpp Unterstützung installiert, kann man auch wenn man root-Rechte hat, keine Screenshot via App machen. Um dies zu umgehen kann man die “Android Debug Bridge (adb)” verwenden.

sudo apt-get install ffmpeg
/opt/android-sdk-linux_x86/platform-tools/adb pull /dev/graphics/fb0 fb0
ffmpeg -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb32 -s 320x480 -i fb0 -f image2 -vcodec png image.png

 

Das gleich Verfahren kann man auch unter Windows anwenden und wer lieber mit einer GUI arbeitet, sollte sich einmal QtADB anschauen. ;)

SSH-Server auf deinem Android (CyanogenMod)

In dem “CyanogenMod” (CM) ist bereits ein SSH-Server eingebaut (Dropbear), dieser ist jedoch standardmäßig abgeschaltet. Hier zeige ich kurz wie du diesen unter Linux / Windows nutzen kannst und dich somit ohne Kabel mit deinem Android (funktioniert nach meinen Tests, nur im lokalen W-Lan) verbinden kannst …  ;-)

 

1.) Android: Vorbereitungen

adb shell

(adb shell)

mkdir /data/dropbear
cd /data/dropbear
dropbearkey -t dss -f dropbear_dss_host_key
dropbearkey -t rsa -f dropbear_rsa_host_key

 

2.1) Linux: Vorbereitungen (Debian / Ubuntu)

2.1.1) Installiere den SSH-Client

sudo aptitude install ssh-client

2.1.2) SSH-Schlüssel generieren

ssh-keygen -t rsa

2.1.3) Übertrage den SSH-Schlüssel (öffentlich / public) zu Android

adb push ~/.ssh/id_rsa.pub /data/dropbear/.ssh/authorized_keys

 

2.2) Windows: Vorbereitungen
PuTTY Download Page

2.2.1) Download “PuTTYgen”

2.2.2) SSH-Schlüssel generieren

Klick auf “Generate” und füge die Zeichenkette, welche du nun im Fenster von puttygen siehst (Beispiel: “ssh-rsa AAAAB3…hclQ==rsa-key-20100227″) in eine Text-Datei auf deinem Desktop ein -> “id_rsa.pub” und speichere (beschütze) deinen “private key”!!!

2.2.3) Übertrage den SSH-Schlüssel (öffentlich / public) zu Android

adb push  C:\Users\[USER]\Desktop\id_rsa.pub /data/dropbear/.ssh/authorized_keys

 

3.) Android: SSH-Server aktivieren

adb shell

(adb shell)

chmod 600 /data/dropbear/.ssh/authorized_keys
echo "/system/xbin/busybox sh" > /data/dropbear/.profile
chmod 755 /data/dropbear /data/dropbear/.ssh
chmod 644 /data/dropbear/dropbear*host_key
chown root.root /data/dropbear/.ssh/authorized_keys
killall dropbear
dropbear -v -s -g

 

4.1) Linux: Verbindung herstellen

-> SSH mit public-key Authentifizierung

 

4.2) Windows: Verbindung herstellen

PuTTY Download Page

4.2.1) Download “putty”

4.2.2) Verbindung zu Android aufbauen

Connection: > “SSH” > “Auth” > wähle deinen gespeicherten “private key” aus …

Session: > gib die IP-Adresse von deinem Android ein und drücke auf Enter

Optimized Android-Apps mit Linux erstellen

Ich habe meine apps mit dem folgenden Bash-Skript optimiert, welches die Bild- & Sound-Dateien komprimiert, so dass die Apps kleiner werden und weniger Speicher verbrauchen… :-)

Habe die optimierten Apps zu meinem Update-Pack für Spica hinzugefügt -> cyanogenmod + x

 

1.) Bash-Skript in einer Textdatei unter Linux speichern (Tweak_app.sh) & Ausführrechte setzen (chmod +x Tweak_app.sh)

2.) “optipng”, “pngcrush”, “sox” installieren (z.B. für Debian: apt-get install optipng pngcrush sox)

3.) android-sdk herunterladen & sudo cp …..android-sdk/android-sdk/zipalign /usr/bin/

4.) Folgendes Verzeichnis anlegen und zu optimierende Apps darin speichern (./place-apk-here-to-batch-optimize/)

5.) Tweak-Skript ausführen (./Tweak_app.sh) -> Fertig


#!/bin/bash

LOG_FILE="apk.log"

if [ \! -f `whereis optipng | cut -f 2 -d ' '` ] ; then
	echo "ERROR: install optipng (apt-get install optipng)"

Battery Calibration

1.1) Battery Calibration? -> “Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It’s suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.” 

1.2) Battery Calibration! -> “If anyone has a battery drain after an update/kernel change, wipe batterystats via recovery. At first, charge your phone to 100% when it’s on. turn it off and connect the charger again. Wait till the battery on the screen says “battery fully charged”. Disconnect the charger & reboot directly into the recovery and wipe the batterystats.” 

PS: maybe you can also try this App for calibrate your battery -> Easiest way i found to calibrate my battery

2.) More Battery Life Out of Your Android
What do you do when your battery is about to die …??

2.1) Use the Power Widget to Easily Toggle GPS, Bluetooth, Wireless, and Screen Brightness

2.2) 3G - requires a lot of power, so you can choose “2G Only” 

2.3) Backlight - adjust the backlight to be less bright (Settings –> Display –> Brightness)

2.4) Wi-Fi - disable Wi-Fi when you don’t need it

2.5) Bluetooth - disable Bluetooth when you don’t need it

2.6) GPS - disable GPS when you don’t need it

2.7) Disable Apps that Sync Constantly

For example you can use the “k-9″-Email App instead of the built-in Email application and activate the Push technology from “k-9″ to get you mails. 

2.8) Background-Apps

Try the OS Monitor-App to see how much resources your running Apps consume!!!

But also other background-apps like twitter, facebook etc. can reduce the battery-time, so you can change the Update-Interval (Settings –> Background Updates) or try e.g. “MinFreeManager”-app or “SSSwitch” and configure the kernel settings to kill background-apps without installing a app for killing apps BUT this will reducing the multitasking features from your phone! 

2.9) More general Information

-> Complete Guide to Maximizing Your Android Phone’s Battery Life – How-To Geek

3) Battery Manager Apps

Maybe you can also try a Battery Manager App, but I don’t need/use it and if you try the above tips I think you will also not need it 
- “SuperPower
- “JuiceDefender

Cross-Compiling Android Kernel – Samsung GALAXY SPICA I5700

Hier möchte ich kurz erklären wie du mit Ubuntu (oder wie in meinem Fall Lubuntu) den Kernel von deinem Spica neu kompilieren kannst.

 

CAP2011012613141
CAP2011012613141

 

1.) Pakete nachinstallieren
aptitude install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev gawk texi2html texinfo automake libtool cvs gcj git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev texinfo gcj

 

2.) crosstool-ng installieren
cd ~
wget http://ymorin.is-a-geek.org/download/crosstool-ng/crosstool-ng-1.9.2.tar.bz2
tar -xjf crosstool-ng-1.9.2.tar.bz2
cd crosstool-ng-1.9.2/
./configure --prefix=${HOME}/ctng
make
make install

 

3.) Cross-Compiling installieren
export PATH=${PATH}:${HOME}/ctng/bin
cd ~
mkdir toolchain-build
cd toolchain-build

wget http://suckup.de/uClibc-0.9.31.config
wget http://suckup.de/toolchain-build.config
mv toolchain-build.config .config

ct-ng menuconfig
"C-library"  ---> (${HOME}/toolchain-build/uClibc-0.9.31.config) Configuration file 
ct-ng build
Abwarten… und hoffen ;-)

 

———-
ggf. muss man vorher noch die Quellen ändern, falls der Server auf der Gegenseite mal gerade nicht antwortet, in diesem (meinen) Fall war dies “mpfr” …
cd ~/ctng
grep -Ri mpfr * | grep get
vim lib/ct-ng-1.9.2/scripts/build/companion_libs/mpfr.sh
… nun habe ich in der Funktion “do_mpfr_get” die URL zu der angegebenen Datei ersetzt, fertig! Alternativ kann man die Dateien auch per Hand herunterladen und in das Verzeichnis ~/toolchain-build/targets/tarballs/ kopieren… ;-)
———-

 

4.) Kernel-Quellen per git herunterladen und anpassen
cd ~
mkdir i5700.2
cd i5700.2
git clone git://github.com/ch33kybutt/i5700-initramfs-froyo-2.6.29.6
mkdir kernel
cd kernel
git clone git://github.com/ch33kybutt/i5700-kernel
cd i5700-kernel
Nun den Pfad zum initramfs anpassen …
vim config.0.1
z.B.: (lars durch deinen User-Namen ersetzen)
[...]
CONFIG_INITRAMFS_SOURCE="/home/lars/i5700.2/i5700-initramfs-froyo-2.6.29.6/"
[...]
cp config.0.1 .config
… und auch die nächste Datei müssen wir ein wenig anpassen … (wobei ich dies per vim erledigt habe! :wq zum speicher)
vim /home/lars/i5700.2/i5700-initramfs-froyo-2.6.29.6/initrd.arm.initramfs_list
:%s/\/home\/ch33kybutt\/kernel\/i5700-initramfs-froyo-2.6.29.6\//\/home\/lars\/i5700.2\/i5700-initramfs-froyo-2.6.29.6\//g
vim Makefile
[...]
CROSS_COMPILE  := /home/lars/ownapps/arm-spica-linux-uclibcgnueabi/bin/arm-spica-linux-uclibcgnueabi-
[...]

 

5.) Cross-Compiling konfigurieren

make menuconfig
"General setup" -> Initramfs source file ("/home/lars/i5700.2/i5700-initramfs-froyo-2.6.29.6/initrd.arm.initramfs_list")
ggf. Versionsnummer etc. anpassen:
vim ~/i5700.2/i5700-initramfs-froyo-2.6.29.6/init.rc

 

6.) Cross-Compiling durchführen
Habe meinen Kernel mit folgenden FLAGS kompiliert… wenn jemand eine bessere Lösung hat würde ich dieser gerne hören…
make
cd ~/i5700.2/kernel/i5700-kernel/arch/arm/boot/
tar -cvf new_kernel_PDA.tar zImage

 

7.) neuen Kernel auf dem Android installieren
oder man versucht dies per ADB, habe dies jedoch noch nicht getestet…
adb push zImage /sdcard
adb shell
/xbin/bml_flash boot /sdcard/zImage

Screencasts direkt vom Android

In diesem kleinen HowTo möchte ich kurz zeigen, wie man Screencasts von seinem Android erstellen kann.


1.) “droid VNC server”-App installieren

Bevor wir das besagt App über den Market installieren können, müssen wir das Smartphone rooten, dass heißt uns vollen Zugriff auf das Gerät verschaffen. (z.B. für Samsung Spica: Android 2.2 Froyo (CyanogenMod))


2.) per ADB einen Port weiterleiten

Wie die “Android Debug Bidge” im allgemeinen funktioniert habe ich bereis in einem anderem Blog-Post erwähnt -> Android Debug Bridge (adb) – HowTo

In diesem Fall rufen wir folgenden Befehl auf, um einen TCP-Port von Andoid direkt mir einem TCP-Port von unserm Betriebssystem zu verbinden.


adb forward tcp:5901 tcp:5901


weite Infos findest du hier -> developer.android.com/guide/developing/tools/adb.html#forwardports


3.) VNC-Viewer + CamStudio installieren (für Windows)

Nun müssen wir uns nur noch einen VNC-Programm und ein Bildschirm-Recorder installieren, ich habe mich z.B. für “RealVNC Viewer” und “CamStudio” entschieden. Besonders schön finde ich, dass man sein Android auch per VNC steuern kann und so während des Aufnahme das Smartphone gar nicht in die Hand nehmen muss… :-)
