I have similiar problem. I installed Segger J-Link, but my board hasnt been recognized via usb (in control panel i had CP2102 with yellow "!"). So i downloaded drivers to it and now it appears each time i connect my board via USB. But still i can not program my board. nrfjprog in command line says there is no board connected. I can not find any boards via JLink GDBServer. How did you solve the problem to program nrf51822? I am not sure if my motherboard is malfunctioning. The led called SPD (lights up when i connect it for about 10 seconds and then lights down. Is it normal? Hope you can help me. Kalreg.

Thanks for the help. I was wrongly using the BLE400 as if it was the nrf51-DK. I've ordered myself a J-link lite. Thank you for the assistance and apologies for my inexperience.

hello spms1027,

Do you use any kinds of the debugger like J-Link Lite ? If you only use the EVB like this, seems there's no debugger on the EVB. The USB on the board connects to the CP2102, which is a USB to UART bridge. This bridge only connects to the UART peripheral on nRF51, and basically you can not use nRFgo Studio to program the chip through it. nRFgo Studio needs a Segger J-Link to program the nRF5x.
