Netwalker PC-Z1
Build Android 2.3.4
Netwalker PC-Z1除了外型漂亮之外，內部可以研究的東西真是相當多，這些東西包含Bootloader、Kernel、OS等東西，加上官方也釋出Kernel原始碼等資源，因此，算是一台可以讓使用者好好學習、研究嵌入式系統的好機器，雖然該台機器已經停產，不過使用者或許可以到二手拍賣網找尋看看，或許有機會購買到這一台機器，接著司徒要介紹如何編譯Netwalker PC-Z1機器的Android 2.3.4系統，希望讓使用者有機會去研究一下Netwalker PC-Z1機器的Android系統
編譯步驟：
1. Download android source
$ export ANDROID=/home/kanamaru/gingerbread-netwalker $ mkdir -p $ANDROID $ cd $ANDROID $ repo init -u https://android.googlesource.com/platform/manifest -b android-2.3.4_r1 $ repo sync
2. Download kernel source
$ cd $ANDROID $ wget http://netbook-remix.archive.canonical.com/updates/pool/public/l/linux-fsl-imx51/linux-fsl-imx51_2.6.28-15.50fsl1araneo19.tar.gz $ tar zxf linux-fsl-imx51_2.6.28-15.50fsl1araneo19.tar.gz
3. Apply androidzaurus patch
$ cd $ANDROID $ wget https://github.com/androidzaurus/droidwalker/archive/master.zip $ unzip master.zip $ tar zxf androidzaurus-droidwalker-61b2290.tar.gz $ cd jaunty-arm $ patch -p1 < ../androidzaurus-droidwalker-61b2290/diff-araneo-android-2.6.28.patch $ patch -p1 < ../androidzaurus-droidwalker-61b2290/disable_double_buffering.patch $ patch -p1 < ../androidzaurus-droidwalker-61b2290/fbmem_8m.patch $ patch -p1 < ../androidzaurus-droidwalker-61b2290/build-wifi-defconfig.patch
4. Apply another patch
$ cd $ANDROID $ wget http://brain.cc.kogakuin.ac.jp/research/files/vendor_tk-netwalker-gingerbread2.3.4-20110726.tar.gz $ tar zxf vendor_tk-netwalker-gingerbread2.3.4-20110726.tar.gz $ $ANDROID/vendor/tk/patch/tk_patch.sh
5. Build kernel
$ cd $ANDROID/jaunty-arm $ make ARCH=arm CROSS_COMPILE=../prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- netwalker_android_defconfig $ make ARCH=arm CROSS_COMPILE=../prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- zImage modules
6. Build android
$ cd $ANDROID/ $ source build/envsetup.sh $ lunch netwalker-eng $ make -j8 $ $ANDROID/vendor/tk/netwalker/image/netwalker-image.sh
P.S. 結果將存放在$ANDROID/vendor/tk/netwalker/image/gingerbread
