[SOLVED] J-Link Base 9.3, USB not recognized after firmware update

  • [SOLVED] J-Link Base 9.3, USB not recognized after firmware update

    Hello.

    Just purchased a new J-Link Base 9.3 and upon first use was prompted to update firmware. After firmware update, the J-Link is not recognized by the computer. I have checked in Windows device manager and there is no J-Link device listed. Our company has several other J-Link units and they work fine. Have tried this unit on two different computers with same results. J-Link Configuration tool also does not work (because of no USB connection I would assume).

    Purchased the new J-Link Base 9.3 through Digi-key so it should be a legitimate "Real" unit. :)

    The activity LED upon first power is solid for about a second and then enters a rapid flash of approximately 10x a second. No target device is connected to the JTAG port.

    We have some other J-Link units in our office and are being prompted to update but are hesitant to do so.

    Any thoughts.

    Thanks

    Dan

  • Hello Dan,

    Sounds like the USB interface is broken. Can you please write an e-mail to segger.com/support/technical-support/ with a reference link to this thread so we can forward your e-mail internally? Please send us the serial number of the unit in this e-mail.

    What version did you use for the FW update? We are not aware of any issues regarding firmware update and we are pretty sure that there is not an issue because this would result in many people would get in touch with us. Furthermore, we test every firmware before releasing it. Anyhow, we would like double check that this symptom is not a generic issue but was one showed up on the one unit, only.

    Sorry for any inconveniences caused.


    Best regards
