  • J-Link v9

    Hi,

    i'am interested in buying an J-Link emulator for projects at home. I've read about the new J-Link v9 which supports VCOM but can't find a shop to buy those devices. Where can i buy a J-Link (EDU?) v9 with VCOM support?

    Best regards,
    Simon

  • Hi Simon,

    You can buy J-Link EDU for example directly from us.
    segger.com/pricelist-j-link-related.html

    You can also buy it through one of our distributors.

    VCOM needs to be explicitly enabled for the J-Link V9, since it is done in software (no hardware UART pins available on the V9).
    More information about how to enable VCOM for the V9: UM08001 (J-Link User Guide), chapter 5.14 Virtual COM Port (VCOM).

  • Hi Alex,

    thanks for your answer. What exactly does "v9" mean? Is it the hardware version of the J-Link emulator or the version of the firmware? I think the part number (e.g. 8.08.90) describes the hardware version number doesn't it?

    If it is the hardware version how can i ensure that i'll get a J-Link v9 device and not v8? If v9 means the firmware version can i upgrade the firmware of my existing J-Link device to v9 ? (I think the hardware version of my existing device is 8.0 as I can read it from the back).

    Best regards,
    Simon

  • Hi Simon,

    V9 means hardware version.

    A J-Link V8 cannot be upgraded to a V9 via an firmware update.

    On the backside of the J-Link, there is a sticker with a serial number etc. on it.
    There is also a "Version" printed on it. This version describes the hardware version.
    The hardware version is also encoded in the serial number of the J-Link:
    S/N: xx90xxxxx => J-Link HW version V9.0

    I think the part number (e.g. 8.08.90) describes the hardware version number doesn't it?

    No, the part number remains the same, no matter what hardware version it has.

    it is the hardware version how can i ensure that i'll get a J-Link v9 device and not v8?

    Order from us directly. :)
