This is my first time using Nordic SoCs, so forgive me if this is a silly question. I have a Fanstel BT832X evaluation board (model EV-BT840(832)-V4). I tried the Nordic's pca10040 blinky example and it only blinks LED2 and LED4. The pca10040 board definition appears to have the correct LED pin mapping.
This is the Fanstel LED pin mapping : 
From the blinky example, the code initializes the LED pins and starts toggling them one by one, nothing fancy. Why is it not turning on LED 1 & 3? What am I missing?
