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].

make ARCH=arm CROSS_COMPILE=[your cross compiler] zImage modules
For example, if you are using gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabi 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
make ARCH=arm CROSS_COMPILE=[your cross compiler] zImage modules
For example, if you are using gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabi 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
Modify the environment file (setup-env-wl18xx-rmd).
Change '''KLIB_BUILD''' variable
export KLIB_BUILD="<<Path to Linux directory linux-omap-2.6.37 sources directory>>-12"
Load the environment file (setup-env-wl18xx-rmd):
rm ${ROOTFS}/lib/modules/2.6.37-wilink8/kernel/net/wireless/cfg80211.ko
Install the compat-wireless modules to your target rootfs. Change '''KLIB''' variableand '''ROOTFS''' variables
make KLIB_BUILD=${KLIB_BUILD} KLIB=${ROOTFS} install-modules
make ARCH=arm CROSS_COMPILE=[your cross compiler] zImage modules
For example, if you are using gcc-linaro-4.9-2015.05-x86_64_arm-linux-gnueabi 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
