I am receiving an error when connecting to a custom board by running nrfjprog --reset, any similarly with any other commands that require connection.

I am connecting through SWD over jlink to an nRF54L15 QFAA device and jlink commander says it sees 3.3V on startup but does not connect. 

I have probed SWDIO and SWDCLK and both seem connected to the micro and the correct pins.

The error I see in the tty is "-102: Command connect_to_emu_with_snr executed for xxx milliseconds with result -102"

'jlink -v' returns version 8.20 and 'nrfjprog --version' confirms this. (nrfjprog version is 10.24.2 external)

What can I try to fix this? 

Slightly separately, nRFConnect for VSCode is no help and says flashed successfully even with the jlink completely disconnected from the board.

Hi,

Please upgrade to the latest J-Link Software and Documentation Pack, and then try again.

If it still doesn't work:

1. What J-Link programmer are you using?
2. Have you at any point in time successfully programmed, or used other commands, on the board, or on other boards, using the same or similar setup? (If so what board and setup?)
3. Can you share a photo of your setup (with custom board, programmer and all connected wires)? If you don't want to share such a photo in this public thread, then you can create a private thread where you post the photo and refer to this thread.

Regards,
Terje

The problem was due to some legs of the micro being raised. Thank you for your help
