Solutions offered by DENX Software Engineering:
DENX Software Engineering is your competent partner through all steps of
developing software for an embedded systems project:
Cross Development Tools and Target File System
The DENX Embedded Linux Development Kit
provides a complete and powerful
software development environment
for embedded and real-time systems.
It is available for ARM, PowerPC and MIPS processors
and consists of:
- Cross Development Tools
(Compiler, Assembler, Linker etc.)
to develop software for the target system.
- Native Tools (Shell, commands and libraries) which provide
a standard Linux development environment that runs on the target system.
- Firmware that can be easily ported
to new boards and processors.
- Linux kernel including the complete source-code with all
device drivers, board-support functions etc.
- Xenomai (Real Time Framework for Linux)
Extension for systems requiring hard real-time responses.
- SELF (Simple Embedded Linux Framework)
as fundament to build your embedded systems on.
All components of the ELDK are available for free
with complete source code under GPL and other Free Software Licenses.
Also, detailed instructions to rebuild all the tools and packages from scratch are included.
The ELDK can be downloaded for free from our server
as well as several
or ordered on CD-ROM for a nominal charge (99 Euro).
To order the CD please contact
Detailed information about the ELDK is available here
Boot Loader for Embedded Systems
You will need some boot loader before you can run Linux on an
Embedded System. That's what DENX provides - Open Source, of course.
Our boot loader "Das U-Boot" is running on more than 500 ARM, AVR32,
Blackfin, ColdFire, Microblaze, MIPS, PowerPC, SH, x86, ... boards,
including most well-known evaluation boards.
You can find the U-Boot project page at
. The git repository with
the sources is here
You can also download tarballs with the latest released versions from
our FTP server - see directory ftp://ftp.denx.de/pub/u-boot/
Our excellent know-how of U-Boot and extensive experience from
porting U-Boot to many, many evaluation boards and custom systems
puts DENX in an unrivaled position whenever you need help with
U-Boot, for example to get it ported to your hardware.
Embedded Linux Operating System
DENX helps you to get Linux running on your hardware. We port Linux
to your boards, develop device drivers and other low-level or
hardware-related software components according to your specifications.
We try to push the results of our work upstream, so it becomes available
in the standard
Linux kernel tree.
In addition, our development repository is publicly available
Xenomai Real-Time Framework for Linux
For projects requiring support for hard real-time behaviour and/or
emulation of other RTOS (like Vxworks or pSOS)
DENX prefers and recommends to use the
Real-Time Framework for Linux.
As a founding member of the Open Source
Automation Development Lab (OSADL
DENX supports Xenomai as one implementation of the OSADL-featured
hard real-time capable, POSIX standard conforming Linux kernel.
On our Xenomai Projects
page you can
find a list of Xenomai features and extensions that were developed or
driven by DENX.
On September 28, 2009, the Xenomai core development team met with
their users at the first "Xenomai User Meeting"
). Abstracts and PDF copies
of the presentations are available
The list of users and use cases presented at XUM-2009 gives also some
reference for what can be done with Xenomai, and which sort of
companies are relying on this technology.
Graphics Support for Embedded Systems
DENX has in-depth know-how in the development and deployment of
graphics drivers and toolkits for embedded systems. We developed and
support graphics drivers for U-Boot and Linux for several popular
graphics processing units, including for example the
controller family (like Mint, Lime, Coral, Carmine, etc.).
We develop drivers for DirectFB
See for example the application note
Qt for embedded Linux 4.5.2 on MPC5200 based board with Coral-P(A) GDC
Other Cool Stuff
Over time DENX has developed other interesting pieces of software
which we are happy to host in our git

Documentation, Questions & Answers for U-Boot and Embedded Linux
DENX maintains extensive documentation covering all topics needed to
get an Embedded Linux project started, like setup and configuration
of the development host, installation of the
, configuration, installation and use of the
boot loader and the
This also includes advanced topics
like options for root file systems, etc.
A collection of Frequently Asked Questions (with answers!) about
U-Boot, Embedded Linux, and similar topics can also be found
Consulting and Support
DENX provides Consulting and Support Contracts that allow you to get
professional help in your projects whenever you need it.
DENX offers Maintenance Contracts that guarantee you
your hardware will keep working with recent versions of U-Boot, Linux
and xenomai, so you can update your code whenever you want or have
We also offer contracts for Security Updates. With such a contract,
DENX will continuously monitor and evaluate the respective Security
Advisories and check these for relevance for your systems. We then
provide updates or fixes that are relevant for system security
Evaluation Kits, Boards and Debuggers
Our partner company
DENX Computer Systems GmbH
provides a wide range of hardware solutions like evaluation kits,
modules and boards, debuggers, BDJ/JTAG debuggers etc.
