Introduction

This article is for specific 2.6.37.y Linux kernel branch serie.
It is interesting read The Linux kernel article previously.

On this 2.6.37.y version, supported IGEP Processor Boards are:

• IGEP COM MODULE / ELECTRON (IGEP0030)
• IGEP v2 (IGEP0020)

The currently supported IGEP Expansion Boards are as follows:

• IGEP PARIS / BERLIN (BASE0010)

Older IGEP devices (Marvell wifi and NO wifi versions) - P/N: IGEP0020-RCxx, IGEP0030-RExx

Binaries: latest stable kernel version for older IGEP devices is: 2.6.37-10 (20140708)

See Linux_Kernel_2.6.37.y

Newer IGEP devices (TI Wilink8 wifi versions) - P/N: IGEP0020-RF6x, IGEP0030-RG6x

Binaries: latest stable kernel version for newer IGEP devices is: 2.6.37-10-wilink8-0 (20150528)

Build kernel from sources

Download the latest stable version sources and follow next steps:

git clone git://git.isee.biz/pub/scm/linux-omap-2.6.git
cd linux-omap-2.6
git checkout origin/linux-2.6.37.y-wilink8 -b linux-2.6.37.y-wilink8 

Configure Linux kernel for IGEP devices. IGEP is ARM architecture based device. A generic configuration is provided for all IGEP machines, and can be used as the default by

make ARCH=arm igep00x0_defconfig

Then build the kernel and kernel modules. The result will be an zImage file in arch/arm/boot directory. Execute:

make ARCH=arm CROSS_COMPILE=[your cross compiler] zImage modules

For example, if you are using IGEP SDK Toolchain (How to setup a cross compiler) then you should execute following cmdline:

make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules

You can install the kernel modules to your target rootfs

make ARCH=arm CROSS_COMPILE=[your cross compiler] INSTALL_MOD_PATH=[path to your target rootfs] modules_install

Kernel Parameters
