Hi,

No, that version is good and can be used with the latest SDK. Which SDK are you testing with? When I build and run the solution from SDK 2.9.1 on a nRF54L15 DK, I see the PWM signal on LED1 as expected (unfortunately I do not have access to a 0.8.1 PDK, so I am testing on a 0.9.2 DK). Do you see any issues if you debug?

PCA10156
0.8.1

LED & BTN numbers are labeled 0-3.

Is this the problematic version?

Hi,

Which version of the PDK do you have? Very early versions had different GPIO pin mappins for LEDs, so that coul cause problems. Regarding LED numbering, we are in the process of changing the LED numbers on the DKs so that they start from 0 instead of from 1, but this means that in a transition period there will be some inconsistencies.

I fixed it by adding an overlay file.

However, I still don't know, why LED1 is not working?
