nRF52840 DK 3.0.0

I have received a development kit from Farnell. It has version 3.0.0. When I connect an external target, I can't get a connection. It only recognises the onboard chip. An older version (1.1.0), on the other hand, recognises the external target.

Is there a newer manual für this hardware release 3.0.0?

Hello Priyanka,
as I can see in the schematic of version 3.0.0, the signal (EXT_VTG) no longer exists in comparison to version 1.1.0. So no external hardware is recognised. However, I can flash the external hardware via Debug_in. I can't find a more up-to-date user guide than version 1.1.0.
Anyway. I close the issue.
