Try uninstalling and installing the drivers for JLink. You can check if it is recognized by your computer from J-Flash or J-Flash lite. For example, if you try to connect to target from J-Flash (Target -&gt; Connect) and the programmer is not found in your computer, it will pop up a message box: Emulator selection - No emulators connected via USB.</p> <p>You can check in the JLink directory if that dll file exists: C:\Program Files (x86)\SEGGER\JLink_Vxxx</p><div style="clear:both;"></div>
