Using the J-link OB on nRF52840-DK to program nRF54L15

[k.leonhardt]

Hi

I have read that the J-Link OB on nRF DK's can program nRF's other generations that the one on the DK itself by using the J-Tag output connector. But does the J-link OB on nRF52840-DK program nRF54L15.

The reason is that we want to build a base setup for testing an nRF54L15 target using a DK from NordicSemi. But as the DK for nRF54L15 DK has a different connector layout that the Arduino like on the other DK, we want to use the nRF52840-DK. But before purchasing the board, we would like an confirmation of the setup first.

Regards

Yes you can , see datasheet page 20 of nRF54L15DK hardware.

for Programming setup other than the debug out cable , i use from DK P20 output 

(nRF_VDD+ VTG )  ------ target_VDD

GND ------target_GND

SWDIO  ------target_SWDIO

SWDCLK ------target_SWDCLK

SWO ------target_SWO

nRESET  ------target_nRESET

Putting nRF_VDD and VTG together will make your DK to target custom board and provide power as well.

Did you see in my post, that I did not want to use the nRF54L15DK but the nRF52840-DK?
