repo sync經常斷線

1. 修改repo

將REPO_URL中的git:修改為http:

2. repo init -u http://~

3. 修改 .repo/manifest.xml

將Fetch…中的git:修改為http:

USB host 權限檔案修改

在vendor/neo/freerunner/init.gta02.rc

on boot底下加入兩行

chmod 0777 /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-host.0/hostmode
chmod 0777 /sys/devices/platform/s3c-ohci/usb_mode

mokoid.jar的權限設定

在vendor/neo/freerunner/AndroidBoard.mk中

新增一行
PRODUCT_COPY_FILE += \
$(LOCAL_PATH)/com.mokoid.server.xml:system/etc/permissions/com.mokoid.server.xml

當然要先複製XML檔到freerunner底下。

USB-RS232 node 預設權限

修改system/core/init/devices.c

找到 mode_t_get_device_perm 的function

最後一行改成return 0777;

Android on freerunner ubuntu環境建置

首先按照android get source 網站的說明安裝

Ubuntu Linux (32-bit x86)
Required Packages:

$ sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc.

$ sudo apt-get install valgrind

Now verify if you have package fakeroot installed. If not, install it by doing:

$ sudo apt-get install fakeroot

Karmic users can install sun-java5-jdk by adding the following lines to /etc/apt/sources.list:

deb http://us.archive.ubuntu.com/ubuntu/ dapper main restricted
deb http://us.archive.ubuntu.com/ubuntu/ dapper universe multiverse

In addition gcc-4.3, g++-4.3, liblzo2-dev and uboot-mkimage are needed:

# sudo aptitude install gcc-4.3 g++-4.3 liblzo2-dev uboot-mkimage sun-java5-jdk

You need to have sun-java5-jdk installed, as noted above, and you need to point the Android Java variables to the correct location. Something like:

$ export JAVA_HOME= /usr/lib/jvm/java-1.5.0-sun
$ export ANDROID_JAVA_HOME=$JAVA_HOME

Set your environment variables:

$ export CC=gcc-4.3
$ export CXX=g++-4.3

And go:

$ make -j 4 TARGET_PRODUCT=fr

The -j parameter will try to optimise the compilation process. The number should represent the double of the amount of cores on your system. In this example, the source is compiled on a dual core system. NOTE: If you are building the Cupcake branch then you need to specify 'freerunner' as the TARGET_PRODUCT, if you are using a newer branch then use 'fr'

也可以編寫一個shell

$vi start.sh
export JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun
export ANDROID_JAVA_HOME=$JAVA_HOME
export CC=gcc-4.3
export CXX=g++-4.3
make -j 4 TARGET_PRODUCT=freerunner
