This +means that the kernel will expect it to report the Guruplug machine id +2659 instead of the official 3550, and it assumes u-boot doesn't provide +a flattened device tree. If your u-boot uses the Dreamplug id then you +can just remove the section about linux-3.4/arch/arm/tools/mach-types +from dreamplug-3.4.0.patch. If it also provides a flattened device tree, +then you don't need dreamplug-3.4.0.patch at all. + +Using the kernel patches +------------------------ + +Instructions based on freedom-maker's README [1]. + +To compile your own kernel, you can use config-3.4.0-1bauer2-kirkwood as basis. +Follow the following steps on the DreamPlug to compile a new kernel: + + 1. Get the kernel source and other needed packages. + # apt-get kernel-package lzma quilt + 2. Get the Linux 3.4 kernel. + # wget https://www.kernel.org/pub/linux/kernel/v3.0/linux-3.4.tar.bz2 + 2. Unpack it somewhere. + # tar xfj linux-3.4.tar.bz2 + 3. Apply the patches found in with-linux-3.4. + # cd linux-3.4 + # ln -s ../with-linux-3.4 patches + # quilt push -a + 4. Copy the config and compile. + # cp ../config-3.4.0-1bauer2-kirkwood .config + # make-kpkg clean + # make-kpkg --append-to-version -1bauer2-kirkwood --revision=3.4.0-1bauer2 --initrd --cross_compile=- kernel_image kernel_headers + 5. Install the packages. + # dpkg -i ../linux-{image,headers}-3.4.0-1bauer2-kirkwood_3.4.0-1bauer2_armel.deb + +After kernel is installed on device, hooks should be calling: + # flash-kernel 3.4.0-1bauer2-kirkwood + +After that you should get a uImage and uInitrd files under /boot. + +These packages should get a kernel up and running into DreamPlug device. +The compilation process takes 6 hours on the DreamPlug. You will need +approximately 1 GB of free space for the build (including the size of the +unpacked kernel source). + +-- +[1] http://anonscm.debian.org/git/freedombox/freedom-maker.git/ |
