Hi Bojan,

could you please give J-Link Commander a try?
J-Link commander is part of the J-Link software package, which is available free of charge here .

  • Start J-Link Commander (jlink.exe)
  • Type "connect" in order to start a debug session
  • Type in the target device name if asked (Or type "?" for a target selection Dialog)
  • Choose the correct target interface (JTAG/SWD/etc..)
  • Use a valid speed (Default: 4000kHz, try 100-500 if default does not work)
  • [JTAG only]JTAG conf can be default(most of the times)
  • You should now be successfully connected.
If anything fails, could you please post a screenshot of the complete session?

Best regards,
Niklas
