‎Building the kernel

New page

== Overview ==
Linux kernel supplied with the [http://compulab.co.il/products/computer-on-modules/cm-t3730/#devres CM-T3730 Android Demo package] provides support for on-board peripherals and abstracts the functionality provided by the hardware.
Current support coverage is specified at [http://compulab.co.il/products/availability-of-os-and-drivers-for-cm-t3730-sbc-t3730/ O/S support coverage map] page.
CompuLab provides ready-to-run binary kernel images, and source code of the modifications and additions made to the Linux kernel to work properly with CM-T3730 modules.
The kernel binary is optimized for using with Android, however can be used with any Linux root filesystem as well.

== Building kernel for CM-T3730 ==
In this article we assume that the {{filename|/home/development/cm-t3730/android}} directory is used for CM-T3730 kernel development.

=== Getting cross-compiler ===
The recommended pre-built toolchain repository is hosted on the [http://gitorious.org/rowboat/prebuilts-gcc-linux-x86-arm-arm-eabi-4_6 Rowboat Gitorious] website.
* Clone the toolchain repository. By default it will be created in the directory named {{filename|prebuilts-gcc-linux-x86-arm-arm-eabi-4_6/}}.
<pre>
cd /home/development/cm-t3730/android
git clone -b rowboat-jb git://gitorious.org/rowboat/prebuilts-gcc-linux-x86-arm-arm-eabi-4_6.git
</pre>

=== Getting kernel sources ===
The Rowboat Kernel sources repository is hosted on the [http://gitorious.org/rowboat/kernel Rowboat Gitorious] website.
* Clone the kernel sources repository. By default it will be created in the directory named {{filename|kernel/}}.
<pre>
cd /home/development/cm-t3730/android
git clone git://gitorious.org/rowboat/kernel.git
</pre>
* Create a branch for CM-T3730 development. The CM-T3730 patches are generated vs. rowboat-jb-am37x-4.1.2 tag (c83d5f31dd92832fd83db48c073d82546c23eeab commit) in the Rowboat kernel tree. It is recommended to use exactly the same baseline to avoid merge conflicts:
<pre>
git checkout -b cm-t3730-dev rowboat-jb-am37x-4.1.2
</pre>
* Apply the CM-T3730 patch:
<pre>
cd /home/development/cm-t3730/android/kernel
git apply /path/to/cm-t3730-android/kernel/linux-2.6.37-cm-t3730-1.patch
</pre>

=== Building the kernel ===
* Setup the toolchain
<pre>
export PATH=/patch/to/cross/compiler/prebuilts-gcc-linux-x86-arm-arm-eabi-4_6:$PATH
export ARCH=arm
export CROSS_COMPILE=arm-eabi-
</pre>
* Build the kernel
<pre>
cd /home/development/cm-t3730/android/kernel
make cm_t3730_android_defconfig
make menuconfig
make uImage
</pre>

In the example above, the Linux kernel image ({{filename|uImage}}) will be created in {{filename|/home/development/cm-t3730/android/kernel/arch/arm/boot}} directory.
{{Note|There is no need to build and install any kernel modules into the Android Demo image for CM-T3730, as all the kernel driver modules are compiled in the kernel binary.}}
