This section shows basic steps how to compile a custom Linux kernel.

== Linux 4.14 ==

=== Set toolchain ===
Export [[i.MX25_SODIMM_PC_Toolchain|toolchain variables]] for every related terminal session.

=== Download and extract source code ===
<syntaxhighlight lang="bash">
mkdir -pv ~/workdir/vmx/linux/
cd ~/workdir/vmx/linux/
git clone https://github.com/voipac/linux.git linux-voipac
cd linux-voipac
git checkout linux-4.14
</syntaxhighlight>

=== Compile ===
Following ouptut files are generated:
* arch/arm/boot/zImage
* arch/arm/boot/dts/imx25-voipac-vmx25-254.dtb
* arch/arm/boot/dts/imx25-voipac-vmx25-264.dtb
* arch/arm/boot/dts/imx25-voipac-vmx25-265.dtb
<syntaxhighlight lang="bash">
cd ~/workdir/vmx/linux/linux-voipac
#make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- imx_v4_v5_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j8
#sudo make ARCH=arm INSTALL_MOD_PATH=/srv/nfs/vmx25-rootfs modules_install
</syntaxhighlight>

== Linux 3.12.13 ==
=== Set shell variables ===
<syntaxhighlight lang="bash">
LK_VERSION=3.12.13
SW_VERSION=20151129
LK_VNAME=${LK_VERSION%[-.]*}
</syntaxhighlight>

=== Download and extract source code ===
<syntaxhighlight lang="bash">
mkdir -pv ~/workdir/vmx/linux/
cd ~/workdir/vmx/linux/
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-${LK_VERSION}.tar.xz
tar -xvJf linux-${LK_VERSION}.tar.xz
mv linux-${LK_VERSION} linux-${LK_VNAME}.orig
cp -rv linux-${LK_VNAME}.orig linux-${LK_VNAME}.work
</syntaxhighlight>

=== Voipac patches apply ===
<syntaxhighlight lang="bash">
cd ~/workdir/vmx/linux/
wget https://www.voipac.com/downloads/imx/25/src/kernel/linux-${LK_VERSION}_vmx25_${SW_VERSION}.patch
wget https://www.voipac.com/downloads/imx/25/src/kernel/linux-${LK_VERSION}_vmx25_${SW_VERSION}.cfg
cd ~/workdir/vmx/linux/linux-${LK_VNAME}.work
patch -p1 < ../linux-${LK_VERSION}_vmx25_${SW_VERSION}.patch
cp ../linux-${LK_VERSION}_vmx25_${SW_VERSION}.cfg .config
</syntaxhighlight>

=== Compile ===
Output files are called arch/arm/boot/zImage and arch/arm/boot/dts/imx25-vmx25.dtb.
<syntaxhighlight lang="bash">
cd ~/workdir/vmx/linux/linux-${LK_VNAME}.work
#make ARCH=arm menuconfig
make -j4 zImage imx25-vmx25.dtb
#sudo make ARCH=arm INSTALL_MOD_PATH=/srv/nfs/vmx25-rootfs modules_install
