Today I've build my first linux system, not completely from scratch, but at least from the basics of an OS: the kernel and the root filesystem. I have followed the nice Embedded Linux Development lecture course from Richard A. Sevenich. In short:

You need 3 things to build a bootable linux system:
  • a kernel: I've downloaded 2.6.5 from www.kernel.org. make xconfig, make bzImage, that's it.
  • a root filesystem: this is the required directory structure and basic applications you will need to run the system. The easiest way is to use busybox (common UNIX utilities) and tinylogin (Unix utilities for handling logging, authentication, users...). How to do it is explained in the article.
  • a bootloader: you can take syslinux for floppy, CD-ROM, network or USB.


    A graphical overview of the build process can be find in Build_Process.pdf

    17.4.04 23:30 Introduction to Embedded Linux Development ( , , , )

    Zaurus: Introduction to Embedded Linux Development. Script from Richard A. Sevenich. He explains embedded systems and how to build an OS for them, based on Zaurus. You lean to build a kernel and roofs (busybox, tinylogin) in order to build a floppy/CD system, configure your build machine (cross compiler) and generate an own initrd for the Zaurus.

    12:06 Pretec CompactLAN and OpenZaurus ( , , , )

    Zaurus: this is an old problem I had with my Pretec CompactLAN card on OpenZaurus, but as some people asked me for a solution during last weeks, here the solution. It seems that different kind of Pretec CompactLAN cards exist, reporting different identities. You can check the identity of you card by typing "cardtl ident". My card returns "Ethernet CompactLAN 10BaseT 3.3V" (with big B in Base). Other cards return "Ethernet CompactLAN 10baseT 3.3V" (with smal B). OpenZaurus only knows the 'small B' card type. To change it, edit /etc/pcmcia/config, duplicate the CompactLAN entry and change it to 'big B'. Next time you insert the card it should be automatically recognized.

    3.4.04 14:39 J2ME tutorial ( , , , )

    I have written a small tutorial about J2ME installation, development, deployment and test. It shows how to setup up your development environment using Eclipse, Sun Wireless Toolkit and EclipseME plug-in. At the end you will be able to upload your midlet application to a web server and make it available to everyone.
