nRF51822 connot be detected by Segger on nRF51 DK.

teddy.c

I have tried to flash my application targeting nRF51822 on our board by using a Segger on nRF51 DK. However, Keil compiler always shows that it couldn't find any nRF51822 target (and always flashes the nRF51422 on the nRF51DK).

I am not sure that I set the hardwares correctly. You could see the my hardware setup in the attached picture.

However, there is no additional power supply for our board. It is just connected with the VCC and GND from P20 of the nRF51 DK.

Would you please help me to solve this proble? Thank you very much.
