Only SWD? You need more connections. See nRF51 DK User Guide Section 5.10 for more information. There are also several questions about this already, try searching. Keil will only detect the on board programmer, not what chip that is connected to the on board programmer.

this will be present in the project folder in your IDE , go to Options > C/C++ complier >Preprossor defined symbols

Can you please tell on which .h library file these statements are present?

I have taken the Swd from the DK and connected to my board. I tried to flash the program through the keil. In the debug settings it is showing the arm core. But how will i know that is it shoeing the chip of the DK or the chip in my board because we are programming both the chip paralelly.

How can i pogr.am using nrf 51 dk. I have tried with the keil But its not working.

Have you tried to program something simpler to it? To check if it works? For example just blinking a LED or something. You could also try to program it using the nRF51 DK.

Yes, I have made the same circuit as in the development board nrf 51 dk.

For custom boards , kindly please read the datasheet because for some boards custom_boards.h library file need to be included in the IDE and the preprossor defined symbols must be changed from

BLE_STACK_SUPPORT_REQD BOARD_PCA10028 S110 NRF_LOG_USES_UART=1NRF51SOFTDEVICE_PRESENT SWI_DISABLE0

BLE_STACK_SUPPORT_REQD BOARD_CUSTOM S110 NRF_LOG_USES_UART=1NRF51SOFTDEVICE_PRESENT SWI_DISABLE0

this worked for me

Yes Peter, its my custom board

Yeah exactly. It is a custom board designed for my application.

What do you mean by "my chip"? Is this a custom board?
