When porting to v2.9.0, the MCU does not function.

[SunHuang]

I attempted to flash the Matter lock example to my custom board, but the MCU shows no activity.

Back in v2.6.1, I used the following configuration, which worked.

How should I implement this in version 2.9.0?

CLOCK_CONTROL_NRF_K32SRC_SYNTH=n
CONFIG_SOC_ENABLE_LFXO=y
CONFIG_SOC_LFXO_CAP_INT_7PF=y
CONFIG_BOARD_ENABLE_DCDC_HV=n

CONFIG_SOC_HFXO_CAP_INTERNAL=y
CONFIG_ SOC_HFXO_CAP_INT_VALUE_X2=14

Hi,

In 2.9.0 the configurations you need to enable the regulators in dts as well. Unfortunately this is poorly documented as of now, but you can see it here: https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/releases/migration-guide-4.0.html#regulator 

Let me know if this resolves the implementation

Kind regards,
Andreas
