Hello Everyone,
Happy New Year !
We would like to evaluate nRF54L15 system off/deep sleep mode current consumption. So we have tried the existing example (https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/boards/nordic/system_off) from Nordic Connect SDK V2.9.0 , but we are getting errors runtime as below.
We are using nRF54L15-DK for evaluation.
