Getting started with Eval board

[SidPrice]

I have just received my nRF52 development board and I have tried to program one of the pre-bjui;t examples (Blinky). The USB drive on the board appears and if I drag the hex file for the board (10040) onto the drive, the file copies but nothing occurs on the board. The file remains visible until I restart the board.

I was expecting the file to be flashed and the example to run. Pressing buttons does nothing.

Hello,

I have just received my nRF52 development board and I have tried to program one of the pre-bjui;t examples (Blinky). The USB drive on the board appears and if I drag the hex file for the board (10040) onto the drive, the file copies but nothing occurs on the board.

Could you confirm for me which Blinky application you are using - is it the hardware peripheral(no SoftDevice/BLE capabilities) version, or one of the BLE blinky examples? 

The file remains visible until I restart the board.

I was expecting the file to be flashed and the example to run. Pressing buttons does nothing.

Yes, if you drag and drop the prebuilt hex file into the JLink then the debugger leg should flash quickly on the device, and the JLink device should restart by itself, starting up with the newly flashed firmware. However, if you are using the hardware blinky example, then the leds will blink regardless of button pushes. If you are using the BLE blinky examples, then LED 1 will be on to signalize that the device is advertising/not connected to any other device. While in this state, button pushes will do nothing, if I recall correctly.

Lastly, I just tried tested the SDK 16 hardware peripheral blinky application on my own nRF52 DK, and it behaved as expected.
Which SDK version are you using?

Best regards,
Karl
