The IDAP-Link has builtin level shifter supporting 1.8v-3.6v. Is your board powered on ? Pin 1 should connect to you 1.8v source if you are not using the ARM SWD connector.

Thank you for your reply, Häkon. Just let me check the Segger probe and I will update here.

Hi,

Have you checked if your debugger is 1.8V capable? It looks like it is only 3.3V capable.

[quote user=""]2. Is there a better way to work with 1.8V in a nRF52?[/quote]

You can use a segger base debug probe, which has a wider voltage range:
