  • ULINK2 USB电脑无法识别(连接电脑后,设备管理器显示未知设备)

    ULINK: No ULINK Device Found


    Information in this knowledgebase article applies to:

    • MDK-ARM V4.70 and later versions
    • MDK-ARM V5 -- All versions

    QUESTION

    I just updated my MDK-ARM to V4.70 (or later version), and ULINK2 downloads and debugs OK using that version. But I also have an older version of MDK on my PC and now I can no longer download using ULINK2 with the older version. How can I correct this?

    ANSWER

    You need to reconfigure your ULINK2 adapter. To do this:

    1. Connect your ULINK2 to your PC. Do not connect it to a target board.
    2. Open a DOS command window.
    3. Assuming you installed MDK V470 (or later version) at C:Keil, run the following case sensitive command:
    4. C:KeilARMULINKUtilitiesUL2_Configure.exe B0
      

      If you installed V470 (or later version) in another location, replace C:Keil with your installation path.
      Note: The last two characters are "B[zero]" NOT "B[capital O]"

    5. You should see:

      Disconnecting from ULINK ...........
      Connecting ULINK Loader....................................
      Updating configuration ...
      Configuration Updated!
      Disconnecting ULINK Loader ..........
      

    Now ULINK2 should work with V4.70 (and later versions) and your older version.
