This article is for specific 2.6.37.y Linux kernel branch series. All the steps has been tested with [http://releases.ubuntu.com/12.04/ubuntu-12.04.5-desktop-amd64.iso Ubuntu 12.04 64b] and [httpshttp://releaseslabs.linaroisee.orgbiz/15index.05php/components/toolchain/binaries/arm-linux-gnueabi/gcc-linaro-4How_to_setup_a_cross_compiler#IGEP_OMAP3 IGEP SDK Yocto Toolchain 1.9-20152.05-x86_64_arm-linux-gnueabi.tar.xz gcc-linaro-4.9-2015.05-x86_64_arm-linux2-gnueabi3].

Also, it could download from GIT Repositories ([http://git.isee.biz/ http://git.isee.biz/]) and test the last unstable version at your own risk (see "''Linux mainline tree (development)''" chapter in [[The Linux kernel]])<br>

== Important procedures == * Remove rootfs modules binaries from any previous Kernel* If you switch to another configuration, clean kernel sources with command: make mrproper == igep00x0_defconfig == '''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 OMAP3 old Marvell WIFI:

For example, if you are using IGEP SDK Yocto Toolchain (then you should execute following cmdline:   make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules You can '''install''' the kernel image to your target boot   cp arch/arm/boot/zImage /media/boot/zImage You can '''install''' the kernel modules to your target rootfs  make ARCH=arm modules_install INSTALL_MOD_PATH=[path to your target rootfs] == igep00x0_wilink8_defconfig == '''Configure''' Linux kernel for IGEP OMAP3 new WiLink 8 WIFI:  make ARCH=arm igep00x0_wilink8_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=[How your cross compiler] zImage modules For example, if you are using IGEP SDK Yocto Toolchain then you should execute following cmdline:   make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules You can '''install''' the kernel image to your target boot   cp arch/arm/boot/zImage /media/boot/zImage You can '''install''' the kernel modules to your target rootfs  make ARCH=arm modules_install INSTALL_MOD_PATH=[path to your target rootfs] Download and extract Compat Wireless source:<pre>cd ..wget http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-12/compat-wireless-wilink8-0.tar.gztar -xvf compat-wireless-wilink8-0.tar.gz</pre> Modify the environment file (setup-env-wl18xx-rmd). Change '''KLIB_BUILD''' variable export KLIB_BUILD="Linux directory linux-omap-2.6.37-12"Load the environment file (setup-env-wl18xx-rmd):  source setup a -env-wl18xx-rmd Compile the Compat-Wireless modules:  cd compat-wireless-wilink8-0 make KLIB_BUILD=${KLIB_BUILD} modules Remove old mac80211.ko and cfg80211.ko modules:  rm ${ROOTFS}/lib/modules/2.6.37-wilink8/kernel/net/mac80211/mac80211.ko rm ${ROOTFS}/lib/modules/2.6.37-wilink8/kernel/net/wireless/cfg80211.ko Install the compat-wireless modules to your target rootfs. Change '''KLIB''' and '''ROOTFS''' variables  make KLIB_BUILD=${KLIB_BUILD} KLIB=${ROOTFS} install-modules Download Wilink 8 binaries:  wget http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-12/ti-connectivity-wilink8-0.tar.gz Copy WiLink 8 binaries to rootfs/lib/firmware:  sudo tar -xvf ti-connectivity-wilink8-0.tar.gz -C /media/rootfs/lib/firmware  == igep00x0_nowifi_defconfig == '''Configure''' Linux kernel for IGEP OMAP3 without WIFI:  make ARCH=arm igep00x0_nowifi_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 Yocto Toolchain then you should execute following cmdline:

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

<br> You can '''install''' the kernel modules image to your target rootfs boot
