This page will to get you started with a custom Mer 'product' using one of the more popular hacker-friendly pieces of hardware.
Contents |
Introduction
First some terminology; Mer is a core OS for vendors who want to make products. So
- a product; is a mix of Mer Core, a HW adaptation and a UX
- a UX; is the graphical user interface or the "User Experience"
- a HW Adaptation; is the tailored kernel, modules, GLES drivers etc built for a specific device
Get started
Prerequisites:
- a MeeGo Community OBS account
- Install the Mer Platform SDK
- Familiarity with 'osc' (See http://wiki.meego.com/Getting_started_with_OBS)
- One of the following devices
* N900 * ExoPC * ...
Summary
We will:
- Build a minimal image using pre-prepared packages
- Boot the device
- See the UX
- Connect using ssh
- Copy the supplied UX package
- Modify the .ks
- Rebuild the image
- Boot the device
- See the modified UX
Create sample image for your device
These steps will download everything needed for the image into a format suitable for installing on the device.
All commands are run inside the SDK.
N900
mkdir n900 cd n900 curl -O https://raw.github.com/lbt/mer-minimal/master/n900/minimal-n900.ks
The N900 can run USB and wifi networking. Setting up USB0 via the .ks is not yet complete.
For wifi edit the .ks and set the SSID name and passphrase; if you have a local dyndns then setting the HOSTNAME works.
I do this and use the modified .ks in the mic command.
sed -e's/<WPA2 passphrase>/MyWPAPhrase/;s/<SSID NAME>/MySSID/;s/localhost.localdomain/MYHOST/;' minimal-n900.ks > minimal-n900.ks-phrased
sudo mic create raw minimal-n900.ks --record-pkgs=name --pkgmgr=yum --arch=armv7hl --compress-disk-image=bz2 -o .
If you want to explore the rootfs before flashing (or for debugging purposes):
sudo mic create fs minimal-n900.ks --record-pkgs=name --pkgmgr=yum --arch=armv7hl -o root
To install the image to the device first see the Nemo N900 installation instructions and then the image writing instructions.
ExoPC
mkdir exopc cd exopc curl -O https://raw.github.com/lbt/mer-minimal/master/exopc/minimal-exopc.ks
The exopc runs wifi networking.
For wifi edit the .ks and set the SSID name and passphrase; if you have a local dyndns then setting the HOSTNAME works.
I do this and use the modified .ks in the mic command.
sed -e's/<WPA2 passphrase>/MyWPAPhrase/;s/<SSID NAME>/MySSID/;s/localhost.localdomain/MYHOST/;' minimal-exopc.ks > minimal-exopc.ks-phrased
sudo mic create liveusb minimal-exopc.ks-phrased --record-pkgs=name --pkgmgr=yum --arch=i686 -o .
To install the image to the device see the x86 installation instructions. Once installed you should be able to boot from the USB stick and ssh in.
Once installed the installer-shell command should copy from the liveusb to the hard-disk.
Networking
N900/N950 + USB
ExoPC + Wifi
RasPi + Ethernet
VM + virtual interface
Next steps
Use your own UX code + repos
osc copypac home:lbt:Mer:UX mer-not-a-ux home:$USER
Change the code and rebuild the package
Change the .ks to point to your repo
Creating ks from .yaml
sudo zypper in mer-kickstarter-configs
