Hello Turbo J , hope you have a good day.
I want to ask how to drive led with gpio like the setup I have (pull down led, active high). I should have make it active low but .... And the voltage between P.10 (mesure by the R1 pad) vs GND is just 0.8V.
Is this purely hardware fault or something else in the code?

P.S: Just trying to salvage the rev1 of this board, currently working on rev2 to impliment some fix.

Thank you so much for the fast reply, you sure is Turbo.

The color of the led is my mistakes when designing the board pcb, in the end we ended up using all red led. After adding "CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y" the code work perfectly and the board now send rtt log.

With 1.8V VDD I would expect neither green nor blue LED to light up - that voltage is only enough for red LEDs.

If you don't have the 32.768kHz crystal populated, you need CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

Otherwise the code won't work.
