NRF52 DK - Blinky Example, LED not Blinking

[Pradeep]

Hi,

I am trying to flash the blinky example from nRF5_SDK_12.0.0_12f24da, the program compiles and is also downloaded to the NRF52 DK successfully. But the LEDs are not blikning.

Could you point out where I am going wrong.

Are you using the standard blinky example or the BLE Blinky Application? Does it work if you program the precompiled blinky hex file? Have you programmed a softdevice to the board? This is necessary if you use the BLE example, but should not be programmed if you use the standard blinky example. Have you tried performing a board erase?

I am using the standard blinky example. Yes, the precompiled blinky hex file works.

Yes I have programmed the soft device on board and then program the BLE Blinky Application. Still the LEDs dont blink. Am I missing something here?

Did you change any of the files in the SDK? Can you try extracting a fresh copy of the SDK and retry compiling and flashing the blinky example? You will not need a softdevice if you use the standard blinky.
