mcu hang at nrf_grtc_sys_counter_low_get

[Liny]

I am using ncs to develop for NRF54L15. It runs fine on the development kit DK, but it doesn't work properly on my own hardware board. My program always fails to simulate, and the pointer stops at this location:

The SDK I am using is version 3.0.2. Below are  part of the schematic.  chip marking is N54L15QFAAC02526AA, andCould you assist me in identifying the issue， or how to avoid this? thands.


there is no 32.768k in my board,so i CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y in prf.conf, but it didn't work

when i debug ,i found clock src is HFsync,it didn't work

Hi,

 

there is no 32.768k in my board,so i CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y in prf.conf, but it didn't work

You should try CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y instead, as the _SYNTH will have a dependency on your HFXO.

However, this indicates then that your design has problems booting up the 32M XO.

 

Could you try with the 32k RC oscillator, and then see if things boot up?

 

Kind regards,

Håkon
