I want to use the debug out on the nrf54l15 DK development board to program my custom board,However, I don't have a compatible cable, so I can only solder the cable onto the P19 pad of the development board。
Below is my wiring diagram, showing the connections between the debug out on the nrf54l15 DK development board and my custom board

However, the connection was unsuccessful, and VSCode still displayed the chip on the development board, not the chip on my custom board
