 RE: nrf54L15 LFRC 32KHz clock configuration issue 

As the poster above mentioned, the nRF54L15 ENGA version is stuck when initializing the GRTC.

it gets stuck at nrfy_grtc_sys_counter_start().

The SDK is 3.0.2.

Is there an alternative solution to changing to the ENGB version?

Hi Yongwoo, 

The Engineering A revision is not supported in NCS, and was for preliminary engineering sampling only. You will need to get a new DK.. See here:  https://docs.nordicsemi.com/bundle/comp_matrix_nrf54l15/page/COMP/nrf54l15/nrf54l15_nrf_connect_sdk.html and Development hardware
