I am currently using the nRF51422 DK along with the nRFgo Starter Kit. I followed the instructions in the PDF "nRF51422_DK_UG_v2.0," and I attached the nRF51422 with PCB antenna (PCA10006) to the nRFgo motherboard (nRF6310). I then connected the J-Link to the nRF51422, and then to my PC via USB. Next I connected the motherboard to my PC via USB.
I downloaded nRFgo Studio, J-Link software from Segger, and uVision (version 4 and version 5). I then tried to test the toolchain according to page 18 of the PDF. I ran J-Link Commander, and it recognizes my J-Link Lite Cortex-M. I ran nRFgo studio and I was able to select the correct SEGGER and erase all.
Next, I try to program my nRF51422 with the Blinky project. I open uVision v4.0, open the project, and build the project. When I try to build the project, I receive the following: "Error: Flash Download failed - 'Cotex-M0'"
The build output states:
