= Build kernel from sources = '''Download''' the latest stable version sources and follow next steps:   wget http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-12/linux-omap-2.6.37-12.tar.gz tar xzf linux-omap-2.6.37-12.tar.gz cd linux-omap-2.6.37-12 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]]) == 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 OMAP3 old Marvell WIFI:  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 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.

Download the latest stable version sources and follow next stepsFor example, if you are using IGEP SDK Yocto Toolchain then you should execute following cmdline:

wget http://downloads.igep.es/sources/linuxmake ARCH=arm CROSS_COMPILE=arm-omappoky-2.6.37.tar.gz tar xzf linux-omapgnueabi-2.6.37.tar.gz cd [kernel version]zImage modules

A generic configuration is provided for all IGEP machines, and You can be used as'''install''' the default bykernel image to your target boot

make ARCH=cp arch/arm CROSS_COMPILE=[your cross compiler] igep00x0_defconfig/boot/zImage /media/boot/zImage

Then build You can '''install''' the kernel with:modules to your target rootfs

make ARCH=arm CROSS_COMPILEmodules_install INSTALL_MOD_PATH=[path to your cross compilertarget rootfs] uImage modules

The result will be an uImage file in archDownload and extract Compat Wireless source:<pre>cd ..wget http://downloads.isee.biz/pub/armreleases/boot directorylinux_kernel/v2. You can install the kernel modules to your target rootfs 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-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.
