  • [SOLVED] Problems with updating J-Link Firmware V6.16j

    Hello,

    today I installed the J-Link Software V6.16j and tried to update the firmware of the J-Link.
    But something does not work correctly.

    I attached a screenshot of the Log-window.


    I have to dis-/reconnect the J-Link after updating to detect it in again.
    The firmware info then still shows the old version number.

    Anyone else experiences this problem?

    Regards,
    Martin
  • Hi Martin,


    there is no Firmware version number.
    What is the firmware string?
    It looks like this:
    Firmware: J-Link Pro V4 compiled Jul 24 2017 17:06:05


    Best regards,

    Could you post a screenshot showing what you are referring to with "version number"?

  • Hi,


    please don't get this wrong - I just wanted to be sure that we are talking about the same thing.
    I had many inquiries where J-Link software version number and firmware string have been confused.

    What happens if you open J-Link commander(jlink.exe) and accept the firmware update?
    Does it fail every time?

  • Hi Niklas,

    no problem, speaking about the same things is important.

    The Log Window (which is shown during the update process) shows exactly the same as in my screenshot, when using the J-Link Commander.
    The J-Link commander window shows this:

    Source Code

    1. SEGGER J-Link Commander V6.16j (Compiled Jul 24 2017 18:42:58)
    2. DLL version V6.16j, compiled Jul 24 2017 18:42:23

  • Hi Martin,


    could you please give it a try using another PC (Windows/Linux/macOS is OK) and another USB-Cabel while having the J-Link connected directly to the machine, with no HUB etc in between?

  • Hi Niklas,

    I found the issue.
    The J-LInk was connected via a "J-Link USB Isolator".
    After removing the isolator the update went fine.
    It seems, that the J-Link update process does not like the isolator.

    Is this a known limitation, that the isolator may not be connected during a firmware update?

    Best regards,
    Martin
  • Hi Martin,

    Yes, this is a know limitation.
    I am sorry that I did not think of the possibility that you are using a J-Link USB Isolator.
