Hi Efe,

are you using a DK or a jlink to flash your pcb? 

To use a DK you use the debug out pin on the DK, and connect to the SWD interface on your pcb. Remember that you need to externally supply your pcb. 



Best regards,

i dont think i made a reset pin extention on my board so i cant measure it . Do i need to do any thing else other than connecting the cables and opening segger embedded studio , target , connect j-link ? am i doing it from the wrong place ? can you pls demonstrate step by step which buttons should i pres after connecting the cables

Hi there,

• Can you measure directly on the VDD pin on the IC and confirm that you measure 3V?
• Could you share your schematic(I can make the case private first)?
• How many samples do you see this issue on?
• You should not connect VTG to VDD on the nRF if you are already supplying the board externally. Then you only need to connect VTG to VDD on your custom board.

 Not really it should be pretty straightforward. You only need to connect the custom board to either the P19 or P20 debug out header on the development kit. If the board is supplied externally then you don't need to supply VDD from the DK. The debugger on the development kit will flash the custom board instead of the nRF when it detects the supply on VTG.
