You may need to build your kernel (for example, to enable the required modules). To build a kernel for the Wiren Board, you need to use a special repository that contains a kernel adapted for the Wiren Board.

0. The kernel should be built on your Linux desktop (not on the Wiren Board - theoretically it is possible, but it will require several gigabytes of free space, and will take a long time).

Make sure you have git installed(http://en.wikipedia.org/wiki/Git_%28software%29). If not, install it:

sudo apt-get install git

Select a random user name and email:

git config --global user.name "Imya Familiya"
git config --global user.email "vash@adres.ru"

1. Download a set of scripts that makes it easy to build:

git clone git://github.com/contactless/build_kernel.git
cd build_kernel

2. Clone and initialize the Linux repository.

You can clone repository via https (if you have no account on github.com):

git clone https://github.com/contactless/linux KERNEL

or via ssh if you have an account:

git clone git@github.com:contactless/linux.git KERNEL

3. Initialize external modules:

cd KERNEL

git submodule init

git submodule update

4. Install config for build on Wiren Board

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- mxs_wirenboard_defconfig

Building the kernel

The kernel built with the package in tar.gz archives:

./build.sh

Build the Debian package

./build_deb.sh

Installing on Wiren Board

export kernel_version=3.19.0-imxv5-x0.1

(the version string should be taken from the output of the Assembly scripts from the previous paragraph)

Скрипты:

tools/copy_kernel_latest_deb.sh - copies and installs the latest. deb kernel package. Argument: folder with rootfs (or mounted eMMC/microSD drive Wiren Board)
tools/scp_kernel_latest_deb.sh - copies and installs the latest deb package with the kernel. Argument: root@hostname, where hostname is the IP address of the Wiren Board

Managing kernel config

Editing the kernel config

cd KERNEL

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- menuconfig

или

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- xconfig

List of changes relative to the standard config

./config_diff.sh

Applying the changes to the standard config

This item is needed to change the standard configuration of the Wiren Board, for example to send a patch or pull request.

cd KERNEL

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- savedefconfig

cp defconfig ./arch/arm/configs/mxs_wirenboard_defconfig
