The Liquidware BeagleBoard Linux kernel is for beagleboard module development.

Get the kernel source:

$ git clone git://github.com/liquidware/liquidware_beagleboard_linux.git

$ git checkout liquidware

My configuration:

compiler path: /home/eye/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-

sdcard device: /dev/sdi

my machine's processor: 8 cores

mount point for sd card's FAT partition: /tmp/bbfat

mount point for sd card's etx2 partition: /tmp/bbext

.config .config

That makes my make commands the following:

Make Commands

Make is used to build the linux kernel. Before building the kernel, you need to configure your kernel. Use the menuconfig command to select drivers as installed v.s. drivers as modules.

menuconfig:

$ sudo make -j8 ARCH=arm menuconfig CROSS_COMPILE=/home/eye/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-

uImage:

$ sudo mount /dev/sdi1 /tmp/bbfat

$ sudo make -j8 ARCH=arm uImage CROSS_COMPILE=/home/eye/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-

$ sudo cp ./arch/arm/boot/uImage /tmp/bbfat

$ sync

$ sync

$ sudo umount /dev/sdi1

modules modules_install:

$ sudo mount /dev/sdi1 /tmp/bbfat

$ sudo mount /dev/sdi2 /tmp/bbext

$ sudo make -j8 ARCH=arm INSTALL_MOD_PATH=/tmp/bbext modules modules_install CROSS_COMPILE=/home/eye/CodeSourcery/Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-

$ sudo cp ./arch/arm/boot/uImage /tmp/bbfat

$ sync

$ sync

$ sudo umount /dev/sdi1

$ sudo umount /dev/sdi2

RootFS

The following commands extract a fresh pre-built Linux Angstrom rootfs (root filesystem)

#get the rootfs image

$ wget http://www.liquidware.com/code/rootfs-ext2.tar.bz2

$ sudo mv ./rootfs-ext2.tar.bz2 ~/rootfs-ext2.tar.bz2

#mount the ext2 partition

$ sudo mount /dev/sdi2 /tmp/bbext

#start fresh

$ sudo rm -rf /tmp/bbext/*

#go into the drive

$ cd /tmp/bbext

#extract the rootfs

$ sudo tar -xvf ~/rootfs-ext2.tar.bz2

$ sync

$ sync

$ cd ..

$ sudo umount /dev/sdi2
