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:

* 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.

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 raw 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
