can't connect jlink to nRF52840

[sean]

Hi

We can't connect jlink to nRF52840,then we check the voltage of DEC pins, Is this correct?

And what's the function of DEC pins(DEC1\DEC2\DEC5)? The datasheet description is not very detailed.

As Øyvind says, how are you trying to connect it?

And what "J-Link", exactly, are you using?
