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:
- Connect your ULINK2 to your PC. Do not connect it to a target board.
- Open a DOS command window.
- Assuming you installed MDK V470 (or later version) at C:\Keil, run the following case sensitive command:
-
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]" -
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.
