uClinux has successfully been ported to the Cisco 2500, 3000, 4000 routers. The patch allowing uClinux to run on the Cisco 2500/3000/4000 routers was completed by Koen De Vleeschauwer. The picture on the left is of a CISCO 3000 running uClinux at Arcturus Networks' Toronto office. The picture was taken by an AXIS 2100 web camera (also running uClinux).

uClinux is the leader in portability. The wide range of Open Source ports is proof of this. Community members from all over the world have been porting uClinux since its release in 1998. While originally developed for the Motorola 68000 chip, the number of available ports is always expanding. If your port is not listed here, or your commercial product using uClinux is not listed, drop us a note at info@uclinux.org.


Ported Microcontrollers and Microprocessors

  • uClinux on the Motorola DragonBall, and other 68K Derivatives
  • Be sure to download the binaries and source code [here].
    uClinux was first released to the public domain supporting the Motorola DragonBall (M68EZ328), Motorola's M68328, and the M68EN322. Since then, uClinux has grown exponentially, as the worlds greatest MMU-less chips receive there own ports.

  • uClinux on Motorola ColdFire
  • Information on the ColdFire port is found here: http://www.uclinux.org/ports/coldfire/index.html.
    Be sure to download the binaries and source code [here].

  • uClinux on the ADI Blackfin
  • Information on the ADI Blackfin processor can be found at blackfin.uclinux.org

  • uClinux on the ETRAX
  • uClinux on Motorola QUICC - Quad Integrated Communications Controller
  • Information on the mc68360 QUICC port is found here: http://www.uclinux.org/ports/mc68360/README.html.
    Be sure to download the binaries and source code [here].

  • uClinux on the ARM7TDMI and MC68EN302
  • Information on the ARM7TDMI port is found here: http://www.aplio.com/B/B2111.htm
    Information on the MC68EN302 port is found here: http://aplionet.aplio.fr/page2.htm
    Be sure to download the binaries and source code for the ARM7TDMI [here].
    Be sure to download the binaries and source code for the MC68EN302 [here].

  • uClinux on Sigma Design DVD system on chip sets
  • Information on the Sigma Design DVD system on chip products can be found at www.sigmadesigns.com Sigma Designs' reference for this ARM core system on chip makes use of uClinux. Chances are your home DVD player already runs uClinux! A copy of their product release source code can be found [here]
    Information on the ETRAX port of uClinux is found here: http://www.developer.axis.com/software/.
    Be sure to download the binaries and source code [here].

  • Information on the i960 port of uClinux is found here: http://www.cse.ogi.edu/~kma/uClinux.html
    Be sure to download the binaries and source code [here].

  • uClinux on PRISMA

    More information on this hobbyist project is found here: http://ds.dial.pipex.com/town/way/fr30/

  • uClinux on Atari 68k

    More information on this hobbyist project is found here:http://www.esat.kuleuven.ac.be/~pcoene/atari.html

  • uClinux on the Microblaze

    Microblaze is a highly-parameterisable 32 bit RISC soft-core processor targetted for Xilinx FPGAs. The ability to customise the processor (e.g. hardware arithmetic support, caches on/off, flexible bus architecture) creates both opportunites and challenges for Linux kernel configuration.

    The uClinux port to Microblaze was done by Dr John Williams in the Embedded Systems group at the University of Queensland in Brisbane, Australia, and is part of their reconfigurable computing research program. The project home page is http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux. More information on the Microblaze can be found at http://www.xilinx.com/edk.

  • uClinux on the NEC V850E

    The V850E is a small RISC processor designed by NEC, usually used in embedded applications. For more information on uClinux/v850, see the web page at http://www.ic.nec.co.jp/micro/uclinux/eng/ (Japan) or http://www.ee.nec.de/uclinux (Europe), or send email to uclinux-v850@lsi.nec.co.jp.

  • uClinux on H8

    More information on this project can be found in the H8 pages

    Devices running uClinux

  • Arcturus Networks has a microcontroller module designed specifically to run uClinux. It is called the uCsimm. More information can be found at the uCsimm website.

  • SnapGear Inc produces both consumer and developer products based upon uClinux. The SecureEdge (TM) is a family of reference designs for secure, Internet-ready appliances. As a development platform the SecureEdge (TM) makes it is easy to quickly prototype deeply embedded applications. Customers have built diverse applications such as gas station forecourt control with e-commerce, government sports/betting regulatory controllers, and satellite protocol optimized remote access routers. One notable project has been the BMS player developed for MP3.com. SnapGear Inc provides total lifecycle services from conceptual design through to manufacturing and even global fulfillment. Partners include Motorola and Hitachi.

  • Aplio has several uClinux-based products, including the ATMEL ARM7TDMI based voice-over-IP telephone. The Aplio/Phone allows you to talk for as long as you want without incurring any long-distance charges. Aplio also offers the AT91 Development Board. This is a helpful tool for a development team using the Aplio/Trio to design an Internet Appliance.


  • AXIS ported uClinux to their ETRAX chip in order to develop a commercial product, their AXIS 2100 Network Camera. It is a digital indoor camera with direct network attachment.


  • ADOMO have a product line of great ColdFire based set top home thin appliances. Check them out [here], or read [this] article from linuxdevics.com.

  • TABO software developed a Programmable Logic Controller that uses Arcturus Networks' uCsimm and runs uClinux. Read this linuxdevices.com article on it. Contact TABO at tabo@niagra.com.

  • ATMEL has an ARM-based evaluation board, the AT91, that runs uClinux.

  • Arnewsh Inc. also makes evaluation boards that run uClinux.

  • CISCO 2500/3000/4000 Koen De Vleeschauwer has created a patch that allows uClinux to run on older MC68EC030 based CISCO routers (2500/3000/4000). It requires 4MB of RAM. The patch file will be moved into the uClinux archive in the next few days. For now the patch can be found at http://users.belgacom.net/gc376810/uClinux-cisco2500-0.1.tar.gz
