Hi,

I used NCS to compile the project, for the board in question.

If you want to learn how to do this, I would recommend starting with our Developer academy:

Kind regards,

Håkon

Hi,

Here's dtm for the nRF54L15-DK from NCS v2.9.1:

devzone.nordicsemi.com/.../dtm_5F00_nrf54l15dk_5F00_ncs291.hex

You can use the programmer app in nrf connect for desktop to program your board. just point (or drag-and-drop) to this file and write it to your board.

Kind regards,

Håkon

Hi,

Have you flashed any firmware to your nRF54L15-DK?

The device must be loaded with the direct_test_mode firmware for this to work.

Kind regards,

Håkon

Hi,

Which SDK version of DTM did you flash to your device?

When flashing DTM to your nRF54L15-DK, it will present you with two COM ports. Could you check the second COM port in the top-left corner and see if this works?

Kind regards,

Håkon
