Dear Sirs, hello!

I have a new version nRF52840 DK board.Main chip IC is N5340.But When I use external programing function(SWD_SEL,SWD_IO,SWD_CLK).

The nRF connect programmer will show me some error message(as below photo).How to solve this problem?

Thank you!

If you haven't already, please update the nRF Programmer App. If that doesn't work, try programming from another source, such as VSC, or using nrfjprog from the terminal to see whether the issue persists.
