=Build kernel from sources = 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)Download'''<br>the latest stable version sources and follow next steps:
'''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:
make ARCH=arm igep00x0_defconfig
make ARCH=arm CROSS_COMPILE=[your cross compiler] zImage modules
For example, if you are using IGEP SDK Yocto Toolchain ([[How to setup a cross compiler]]) then you should execute following cmdline:
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules
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.

== modules are not installed correctly ==
Try to change rootfs owner from root to your username.
<pre> sudo chown <username> -R /media/rootfs</pre>
== wlcore: Unknown symbol ==
Probably, you didn't erase old module binaries from rootfs. Open IGEP terminal and type:
<pre>depmod -a
depmod -A </pre>
Finally reboot the system
