Linux Kernel 3.14.28.y
From IGEP - ISEE Wiki
Compiler
We recommend to use IGEP i.MX6 Yocto Fido SDK to compile i.MX6 kernels
Download
Install sdk
sh poky-glibc-x86_64-isee-fsl-image-dev-cortexa9hf-vfp-neon-toolchain-1.8.sh
Install target into default directory (/opt/poky/1.8)
Build kernel from sources
Download the latest stable version sources and follow next steps:
For clone linux-imx/
git clone git://git.isee.biz/pub/scm/linux-imx.git cd linux-imx git checkout remotes/origin/isee-imx_3.14.28.y-next -b isee-imx_3.14.28.y-next.local
Export environment variables:
source /opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
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 CROSS_COMPILE=arm-poky-linux-gnueabi- imx6_igep0046_defconfig
Then build the kernel, the kernel modules and the device tree files. The result will be an zImage file in arch/arm/boot directory. Execute:
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules dtbs
You can install the kernel modules to your target rootfs
sudo make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- INSTALL_MOD_PATH=[path to your target rootfs] modules_install
You can install the zImage to boot partition :
cp arch/arm/boot/zImage [path to your target boot]
You can install the IGEP SMARC i.MX6 DTBs to boot partition. You can choose the dtb you need to your machine:
cp arch/arm/boot/dts/imx6q-igep-base0040*.dtb [path to your target boot]
TI Wilink8 Backports
Once you install kernel and module binaries in your rootfs You can download and compile WIFI and Bluetooth modules and applications:
Install dependencies:
sudo apt-get install lib32z1
Download WIFI build-utilities:
git clone git://git.isee.biz/pub/scm/wilink8-wlan/build-utilites.git
Mount your SD card or rootfs and configure setup-env:
cd build-utilites/
cp setup-env.sample setup-env
Add SD or rootfs patch into ROOTFS environment variables and add linux-imx kernel source path into KERNEL_PATH variable
Download sources:
./build_wl18xx.sh init
Compile sources and install binaries:
./sudo_build_wl18xx.sh update R8.6_SP1
During process appear the following error:
ERROR [PATH ROOTFS]/lib/modules/3.14.28-1.0.0_ga+yocto+g34048c3/updates/drivers/net/wireless/ti/wl18xx/wl18xx.ko Not found !
wl18xx.ko is correctly installed. So don't take care of it. Now, your kernel has Wilink 8 support added
