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:\Keil\ARM\ULINK\Utilities\UL2_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.
