nRF52810 ic not recognized by segger J link

[redanb]

SWDIO,SWDCLK,VCC AND GND have been taken out from the nrf52810 ic and proper connections have been made to the jtag end of the j link device (connecting all grounds also) but the target is not recognized by the j link commander.Please guide how to program the nrf52810 ic using J link.

Hello, 

Can you please provide a full schematic as awneil mentions. Similar to the reference layout below:

Please see our other reference layout for nRF52810 here.

Kind regards,

We have not followed the reference layout given above ; we just took out swdio ,swdclk,vcc and gnd from the ic on the pcb so that we can use swdio and swdclk for programming by making the connections as shown above to the 20 pin jtag j link.Will it work ?

Will the above setup work?

How is the nRF52810 powered? Can you please show a picture of your board, with the connections?

[redanb]

I powered it from a different board which is powered by a 3.7v 350 mah battery. Do you think it is a supply problem or ic layout problem?The picture is not clear though.

I'm sorry, but you will need to provide the schematics of your board. 

Are you sure that your board is powered? Have you measured on the device? How have you connected the three (your board, JLink, and different board) together?

 Very difficult to say at this moment. I need to know what is on your board.

Kind regards,
Øyvind

Yes the board is powered , all three are connected.Here are the layouts of the 2 ics we tried upon:
