Nordic nRF52-DK disconnects from computer when I upload the BIN file

[Keith Hammock]

I am attempting to run my first bit of code on my Nordic nRF52-DK and every time I have attempted to upload the code to the board, the board disconnects in the middle of the upload process and then reconnects without the file on it. When I first move the file to the board, the LED is blinking as if it is ready to run code, but then after it disconnects and reconnects, it is no longer blinking, and pressing the reset button does nothing. I explicitly followed the instructions to upgrade the firmware of the device, and I wouldn't think that was a problem anyway since the board recognizes the code file instantly when I upload it as can be seen by the flickering LED. Also, the board will randomly disconnect and reconnect when I am doing other things on my computer. The cable I am using is brand new.

I tried all three USB ports on my laptop and they all did the same thing. I downloaded the JLink driver on my desktop and plugged in the board to all of my USB ports there, and the contents of the board are different then what they are when I plug it into my laptop. I have three files on my laptop, and on my desktop there is only one file. I attempted to upload the firmware update to the board on my desktop, although I have already done it on my laptop, and once again the board just disconnected. I also tried to upload the same bin file and it disconnected as well.
