This is a kernel for Intel Galileo Gen1/2 which will be rebased on and will track Linux stable.

If your Galileo Gen1/2 project requires some of the latest kernel features then this might be the Linux kernel for you.

How to build the kernel?

1.Build a cross-compiler toolchain with Yocto

http://git.yoctoproject.org/cgit/cgit.cgi/meta-intel-iot-devkit/

OR

2.Use a pre-built toolchain from IoT DevKit

https://software.intel.com/sites/landingpage/iotdk/linux-developement-kit.html

NOTE: You will need to execute the 'devkit-launcher' script distributed with IoT DevKit SDK at least once before using the cross-compiler.

After you have built/downloaded the cross-compiler toolchain:

1.Include the cross-compilation tools in your PATH:

export PATH=path_to_sdk/sysroots/x86_64-pokysdk-linux/usr/bin/i586-poky-linux:$PATH

2.Cross-compile the kernel

ARCH=i386 LOCALVERSION= CROSS_COMPILE=i586-poky-linux- make -j8

3.Extract the kernel modules from the build to a target directory (e.g ../galileo-stable-install)

ARCH=i386 LOCALVERSION= INSTALL_MOD_PATH=../galileo-stable-install CROSS_COMPILE=i586-poky-linux- make modules_install

4.Extract the kernel image (bzImage) from the build to a target directory (e.g ../galileo-stable-install)

cp arch/x86/boot/bzImage ../galileo-stable-install/

5.Install the new kernel and modules from the target directory (e.g ../galileo-stable-install) to your micro SD card

5.1.Replace the bzImage found in the first partition (ESP) of your micro SD card with the one from your target directory (backup the bzImage on the micro SD card e.g. rename it to bzImage.old)

5.2.Copy the kernel modules from the target directory to the /lib/modules/ directory found in the second partition of your micro SD card (e.g /lib/modules/3.18.1-galileo-g1)

6.Reboot into your new kernel

NOTE: If you experience any issues with your custom-built kernel you can revert to you kernel backup from step 5.1
