Axis Developer Board LX release 1.0.0
=====================================

This software uses Linux 2.4.3, which takes advantage of the MMU in the
ETRAX 100LX, and does NOT work on the older ETRAX 100 chip. There are two
labels on the developer board, one with the PCB assembly number (on the top of
the board) and one with the Axis part number (on the bottom of the board).
If your board has one of the following combinations of numbers, the chip on
your board is an ETRAX 100LX:

    Axis Part No | PCB ASS
    ----------------------
    0109-xxx-01	 | 17293 4
    0109-xxx-02	 | 18260 1
    0109-xxx-03	 | 18471 1

Otherwise the chip is an ETRAX 100 that cannot run the devboard_lx software
(then use the devboard software: http://developer.axis.com/download/devboard).


Features
--------

The standard C library is uC-libc. All applications are statically linked.
Dynamic linking will be possible in a future release.

The default shell (/bin/sh) is ash (Bourne compatible). The stand alone shell
(sash) is also available (/bin/sash) because of its command line editing.
The boot scripts (rc-scripts) are Bourne shell scripts.

The devboard_lx software is built using make (mkprod and the prodspec file from
the devboard software has been replaced with a Makefile and two specfiles;
makespec and ptablespec).

The directory structure of the devboard_lx software is different from the
devboard software. There is a top-level directory (axis/devboard_lx) which
contains a top-level Makefile. The other directories (apps, libs, packages etc)
are subdirectories:

axis/
axis/devboard_lx/
axis/devboard_lx/apps/
axis/devboard_lx/files/
axis/devboard_lx/libs/
axis/devboard_lx/os/
axis/devboard_lx/packages/
axis/devboard_lx/tools/

The Linux 2.4.3 kernel is not included in the tgz-file (download it from
http://www.kernel.org if you do not have it already).


Known problems
