This section shows basic steps how to compile a custom Linux kernel.
Linux 4.14
Set toolchain
Export toolchain variables for every related terminal session.
Download and extract source code
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
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
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
Linux 3.12.13
Set toolchain
Export toolchain variables for every related terminal session.
Set shell variables
LK_VERSION=3.12.13
SW_VERSION=20151129
LK_VNAME=${LK_VERSION%[-.]*}
Download and extract source code
mkdir -pv ~/workdir/vmx/linux/
cd ~/workdir/vmx/linux/
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-${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-${LK_VNAME}.work
Apply Voipac patches
cd ~/workdir/vmx/linux/
wget http://downloads.voipac.com/files/i.MX25_SODIMM_PC-Development_kit/module/software/linux/sources/linux-${LK_VERSION}_vmx25_${SW_VERSION}.patch
wget http://downloads.voipac.com/files/i.MX25_SODIMM_PC-Development_kit/module/software/linux/sources/linux-${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
Compile
Output files are called arch/arm/boot/zImage and arch/arm/boot/dts/imx25-vmx25.dtb.
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
