I have two JLink ARM adaptors and two of our custom LPC2148 based boards.
Last week at least one of each was working just fine. Coming back to it this week none of the combinations are working.
I tried upgrading to the latest segger driver and software, but still no joy.
Here is the output from jlink.exe when trying to connect:

I get similar issues of failing to connect when using the JLink with the IAR ARM compiler (only went to using JLINK>exe when the IAR compiler failed to connect, repeatedly)
Any pointers or help would be greatly appreciated
