Hello,
I am testing the system off demo on the nRF54L15 DK using nRF Connect SDK v2.8.0 (Zephyr v3.7.99).
I ran the sample exactly as provided in the SDK.
Observed log output:
*** Booting nRF Connect SDK v2.8.0-a2386bfc8401 ***
*** Using Zephyr OS v3.7.99-0bc3393fb112 ***
nrf54l15dk system off demo
Retained data not supported
Entering system off; press sw0 to restart
At this point, the device enters system off.
However, pressing Button0 (sw0) does not wake up or restart the system.
Expected behaviour:
Pressing Button0 should trigger wakeup from system off.
What I already tried:
-
Added
wakeup-source;property tobutton0in an overlay:/ { button0 { wakeup-source; }; }; -
Rebuilt and flashed, but still no wakeup on button press.
Environment:
-
Board: nRF54L15 DK
-
nRF Connect SDK: v2.8.0
-
Toolchain: west build (VS Code)
-
Example:
system_offdemo (unmodified)
QuestionS:
-
Is GPIO (Button0) wakeup from system off supported on the nRF54L15 DK?
-
s there another configuration needed (special GPIOTE setup, power domain setting, etc.)?
-
Has anyone confirmed this demo working on nRF54l15?
