  • [SOLVED]J-Link on Ubuntu 12.04

    Hello.
    I've got a problem with JLinkExe utility under Ubuntu 12.04 precise
    $ uname -r -v -p -i
    3.2.0-22-generic-pae #35-Ubuntu SMP Tue Apr 3 20:37:36 UTC 2012 i686 i386
    When I try to run JLinkExe utility over ./start script, the utility can't find J-Link
    $ ./start
    SEGGER J-Link Commander V4.50i ('?' for help)
    Compiled Jun 22 2012 19:00:38
    Can not connect to J-Link via USB.
    J-Link>

    The same version 4.50 works perfect on previous Ubuntu versions such us Lucid and Karmic
    Thanks.

  • Try the following 45-jlink.rules (/etc/udev/rules.d) and reconnect the J-Link:

    Source Code

    1. SUBSYSTEM=="usb", ATTRS{idVendor}=="1366", ATTRS{idProduct}=="010[1234]", MODE="664", GROUP="plugdev"


    The original udev-rules-file seems not to work with actual udev version.

    CHeitkamp, I was having some trouble recognising my J-Link in a Ubuntu 12.10 virtualbox instance.
    This fixed it perfectly.
    Thanks

  • Hi,

    We just released V4.62 of the J-Link software for Linux. This version comes with an updated 45-jlink.rules.
    This should solve the problem.


    Best regards
