Build WLAN driver and Android Filesystem

1) Patch

Because there are too many warnings when building WLAN drivers. So I turn off the -Werror command line option in the EXTRA_CFLAGS, like

EXTRA_CFLAGS += -fsigned-char
#EXTRA_CFLAGS += -fsigned-char -Werror

Modified files:
1. /opt/L27.12.1-P2/mydroid/hardware/ti/wlan/wl1283/stad/build/linux/common.inc
2. /opt/L27.12.1-P2/mydroid/hardware/ti/wlan/

2) Script used to build WLAN drivers and Android Filesystem

#!/bin/bash
MYDROID=/opt/L27.12.1-P2/mydroid

mkdir -p logs
export KERNEL_DIR=/opt/L27.12.1-P2/kernel/android-2.6.35

make clean
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- -j4 2>&1 |tee $MYDROID/logs/android_make.out

3) Finally, build errors

Building u-boot and x-loader

Pre-requisite packages for build Android Filesystem (Note this is with reference to uBuntu 8.04)
If you are behind firewall, you will have to set-up firewall using the instructions in Support Tools
For higher versions of U-buntu please refer to Host PC COnfiguration
The following commands will install the correct packages to your server:

sudo apt-get install git-core flex bison gperf libesd0-dev libwxgtk2.6-dev zlib1g-dev build-essential libstdc++5 tofrodos
sudo apt-get install x-dev (*** no files existing ***)
sudo apt-get install libx11-dev
sudo apt-get install libncurses5-dev
sudo apt-get install sun-java5-jdk (*** no files existing ***)

If you do not have sudo rights to your machine, contact your System Administrator for assistance. Google has issued that “sun-java6-jdk” has become unsupported: “because of incompatibilities with @Override” To uninstall “sun-java6-jdk” please type:

sudo apt-get remove sun-java6-jdk

“Intrepid (8.10) users may need a newer version of libreadline:

sudo apt-get install lib32readline5-dev” 

1) script used to build u-boot:

#!/bin/bash
make distclean
mkdir -p ./logs
make ARCH=arm omap4430panda_config
make 2>&1 |tee ./logs/u-boot_make.out

2) script used to build x-loader:

Finally, I built u-boot successfully, but there is an error when I

built the x-loader.

Kernel & Driver Source

To clone kernel source from scratch do:

cd $YOUR_PATH/L27.12-P2/
git clone git://git.omapzoom.org/kernel/omap.git kernel/android-2.6.35
cd kernel/android-2.6.35
git checkout ec895072ad0b686d2c130e5d80a3076a03042033

If you already have kernel source cloned then just update it (and add a remote if it is the first time):

cd $YOUR_PATH/L27.12-P2/kernel/android-2.6.35
git fetch origin
git checkout ec895072ad0b686d2c130e5d80a3076a03042033

U-Boot Source

cd $YOUR_PATH/L27.12-P2/
git clone git://git.omapzoom.org/repo/u-boot.git u-boot
cd u-boot
git checkout 601ff71c8d46b5e90e13613974a16d10f2006bb3

Android Version Control with Repo and Git

Reference:
http://source.android.com/source/version-control.html

1) Download repo:

$ curl http://android.git.kernel.org/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

$ set path to ~/bin/repo

2) Basic Workflow

The basic pattern of interacting with the repositories is as follows:

1. Use repo start to start a new topic branch.
   
2. Edit the files.
   
3. Use git add to stage changes.
   
4. Use git commit to commit changes.
   
5. Use repo upload to upload changes to the review server.
