Requirements

  • ARM Cross Compiler: GCC

ARM Cross Compiler: GCC

This is a pre-built (32bit) version of Linaro GCC that runs on generic linux, so 64bit users need to make sure they have installed the 32bit libraries for their distribution.

Debian OS 7,8

dpkg --add-architecture i386
apt-get update
apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386

Download and extract:

wget -c https://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
tar xf gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz
export CC=`pwd`/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-

First Configure:

make ARCH=arm CROSS_COMPILE=${CC} distclean
make ARCH=arm CROSS_COMPILE=${CC} singlecore-omap2plus_defconfig

The .config file will be generated.

Build kernel image, modules, device tree:

make ARCH=arm CROSS_COMPILE=${CC} -j4 LOADADDR=0x80008000 zImage dtbs modules

Install kernel image:

sudo cp -v ./arch/arm/boot/zImage /media/rootfs/boot/zImage

Install modules

mkdir -p /tmp/deploy
make -s ARCH=arm CROSS_COMPILE="${CC}" modules_install INSTALL_MOD_PATH=/tmp/deploy

cd /tmp/deploy
tar --create --gzip --file 3.14.26-modules.tar.gz *
sudo tar vxzf 3.14.26-modules.tar.gz -C /media/rootfs/

cd ..
rm -rf /tmp/deploy

Install Firmware

mkdir -p /tmp/deploy
make -s ARCH=arm CROSS_COMPILE="${CC}" firmware_install INSTALL_FW_PATH=/tmp/deploy

cd /tmp/deploy
tar --create --gzip --file 3.14.26-firmware.tar.gz *
sudo tar vxzf 3.14.26-firmware.tar.gz -C /media/rootfs/lib/firmware

cd ..
rm -rf /tmp/deploy

Install Device Tree

sudo cp -v ./arch/arm/boot/dts/am335x-botbone.dtb /media/rootfs/boot/
