Hi Ralf,

Mikroprog should do it without problems.
You need just 3 wires: GND, SWDIO and SWCLK

Hi Ralf,

If the three wires are properly connected it should work. I assume you flashed your mikroProg to latest version with ST-Link utility.
It is essential that you have the usb cable completely removed from Nucleo board ST-Link V3 programmer.
So you should change JP2 to EXT PWR and apply external 5v to the board. This way the internal programmer will not interfere with external one.

Regards,
Sergiu
