JLINK debugging first try error

I just realized I was using a V9 version. The V8 version shows a single interface as well and in Zadig it looks exactly like your output.

And your probe shows up as a USB device. That’s a good start.

Can you start J-Flash Vxx (a software that comes with the J-Link software) – again with just the J-Link probe (and nothing connected to it):

  • Choose Create a new project and click Start J-Flash
  • Click OK (without changing target device / interface / speed)
  • Select Target > Connect from the menu

Now an error will occur because you have no target connected. But the log output can give some hints. Does it start with something like:

Connecting...
 - Connecting via USB to J-Link device 0
 - J-Link firmware: J-Link ARM V8 compiled Nov 28 2014 13:44:46

If J-Flash can detected the J-Link version, then the communication with the probe is working correctly.
