Hello.

I tried the same sample on nRF SDK v2.8.0, and the logs from my side are below. Could you add the following to prj.conf and see if there’s any change?

CONFIG_APP_USE_RETAINED_MEM=y
CONFIG_RETENTION=y

*** Booting nRF Connect SDK v2.8.0-a2386bfc8401 ***
*** Using Zephyr OS v3.7.99-0bc3393fb112 ***

It worked with SDK v3.0.2. Thanks.

Yes, I tried pressing Button 1, but the device still does not wake up from System OFF. You are using SDK v3.1.0, while I’m working with SDK v2.8.0. I need to get this working with SDK v2.8.0.

I tried adding CONFIG_GPIO_WAKEUP_ENABLE=y, but it still fails for me. I'm working with SDK v2.8.0, whereas you tested it with SDK v3.0.2

Hello,

Have you tried pressing Button 1 on the DK to wake the device from System OFF? I tested this sample on my side, and it’s working fine. Below is the log from the nRF54L15 DK after flashing the sample.

If you’re wondering why you see the “Retained data not supported” message in the log, try enabling the following options: CONFIG_APP_USE_RETAINED_MEM and CONFIG_RETENTION. See here

I tested this recently with 3.0.2 SDK and it worked. Did you configure CONFIG_GPIO_WAKEUP_ENABLE=y ?
