https://devzone.nordicsemi.com/f/nordic-q-a/15646/nrf52dk-getting-startedHi, I have a NRF52DK (Chip Label: PCA10040; V0.9.0; 2015.44; 682646724) and when i try to start the DK as described in the getting startet page, Step 5 failed as LED1 is not blinking. Even pressing Button 1 to 4 does not change anything.
