There is an image to provide a fresh Ubuntu 7.04 (feisty) containing the Openmoko installation as generated by MokoMakefile including working QEMU.
Contents |
[edit] Usage of the chroot image
| NOTE: This Image is outdated (OM 2007.1) |
If you do just want to test some of the functionality and need a starting point,
you can download an ext3 Image.
The Image is just a first test and may contain errors as it's not tested well yet (and the build process was not running through without user interferences).
[edit] Installation
Get the Image (about 3.2 GB) from http://b030.tfh-berlin.de/Openmoko-Dev-x86_2007-07-16.img.bz2: wget http://b030.tfh-berlin.de/Openmoko-Dev-x86_2007-07-16.img.bz2
Check the md5sum:
md5sum Openmoko-Dev-x86_2007-07-16.img.bz2
- it print "41715e06d7e59a94e4f05cf33ba054b5 Openmoko-Dev-x86_2007-07-16.img.bz2"
You will need to decompress the Image (about 15 Gbyte). An you'll also need the chroot software
and loop back device support in your kernel.
bzip2 -d Openmoko-Dev-x86_2007-07-16.img.bz2
To install chroot in GNU/Debian / Ubuntu you can use:
sudo sh apt-get install dchroot
[edit] To mount and activate the chroot image use
mkdir /var/chroot mount -o loop Openmoko-Dev-x86_2007-07-16.img /var/chroot
Add a new chroot configuration:
echo "Openmoko /var/chroot" | tee -a /etc/dchroot.conf
Edit /etc/fstab and insert: /tmp /var/chroot/tmp none bind 0 0 proc-chroot /var/chroot/proc proc defaults 0 0 devpts-chroot /var/chroot/dev/pts devpts defaults 0 0
Tell mount to re-scan fstab and mount the new directories automatically: mount -a
(optional) Manual mount: If you do not want the system to mount these directories at boot, they can instead be mounted by hand. Note that this will need to be repeated each time the system is rebooted: mount -o bind /tmp /var/chroot/tmp mount -t proc proc-chroot /var/chroot/proc mount -t devpts devpts-chroot /var/chroot/dev/pts
Copy your /etc/resolv.conf: cp /etc/resolv.conf /var/chroot/etc/
As the user who started X11: xhost + # assuming you are behind NAT
Start the chroot environment (as root again): dchroot -d -c Openmoko # -d to take the environment variables with you
[edit] Starting the Emulation
You can start the emulation by running: cd /home/moko/openmoko/trunk/src/host/qemu-neo1973/ export DISPLAY=:0.0 arm-softmmu/qemu-system-arm -M neo -m 130 -mtdblock openmoko/openmoko-flash.image \ -kernel openmoko/openmoko-kernel.bin -usb -show-cursor -usbdevice keyboard
[edit] Additional Notes
There is no root password set and no user moko in the systems right now which should not be a problem when used in an emulator or a chroot environment, here you have both.
