This page is dedicated to getting MeeGo running on the Beagleboard. More info on the beagleboard can be found here

Because the processor for the beagleboard C4 is an OMAP3530 and the N900 currently sports a similar processor, it seems wise to start with the ARM page.

Turn key demo image from Linux Foundation for GENIVI consortium

The Linux Foundation developer team put together the following image for demonstration during the Linux Foundation keynote address at the GENIVI conference on May 19. It is based on MeeGo 0.9 and has the SGX drivers built-in. Also preinstalled are the XFCE-Desktop, QT demo applications and 3D SGX demos (/usr/bin/SGX). Just download and write the image to a sdcard (>4GB). This image runs on revision B5 up to C1D/C4 boards. Enjoy!

Kickstart using daily repositories

Use this kickstart file to generate a rootfs for armv7. You will need mic2 & user mode qemu for ARM instruction set.

Usage of mic is described here. You will need at least version 0.19 of mic. As of 2010-06-16 this means installing from git.

mic-image-creator also needs /usr/bin/qemu-arm-static which you can probably find in your distributions packages. For Ubuntu 10.04 this is from qemu-kvm-extras-static. For earlier versions of Ubuntu or Debian you will use qemu-user-static.

Save it as meego-beagle-rootfs-daily.ks and execute it with

sudo mic-image-creator --run-mode=0 --cache=mycachedir --format=fs --arch=armv7l --config=meego-beagle-rootfs-daily.ks

Copy these files to your rootfs and add a kernel and a matching SGX driver.

Another more detailed description of a similar setup can be found at ARM/Meego on Beagleboard from scratch.

Steps to modify an N900 image for BeagleBoard

This section takes an existing N900 file-system image and describes how to rig it to work on a BeagleBoard.

What works so far:

• Take the n900 rootfs and extract to the rootfs partition of the beagle sdcard setup. You can mount rootfs of N900 from this image on /mnt by:
  1. bunzip2 meego-n900-open-armv7l-1.0.0.20100525.1-sda.raw.bz2
  2. sudo mount -o loop,offset=16384 meego-n900-open-armv7l-1.0.0.20100525.1-sda.raw /mnt
• Then sync the contents to your SDcard by:
  1. sudo rsync -aHx /mnt/* /media/your_sd_card
• MeeGo Beagleboard kernel and modules contains precompiled uImage and kernel modules (v2.6.34) for Beagleboard. You need copy uImage to /boot partition of your SD card, and modules to /lib/modules directory on your root file system.
• Log in as root with password meego
• Note: This precompiled kernel/rootfs doesn't contain the sgx drivers.
• Since we are using rootfs tuned for N900, we can stop starting X by replacing id:5:initdefault: to id:3:initdefault: in /etc/inittab.
• To fine tune above kernel follow these instructions:
  1. Copy meego-beagle-kernel.config from above archieve to your kernel compilation directory as .config
  2. make old_config
  3. Tune kernel options using: make xconfig
  4. You can now compile your kernel using: make uImage
