The NRF5340 net core crashes in sdc_hci_cmd_le_set_adv_enable() if I have CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP set to 0.
To reproduce the issue, do the following:
1) Use the attached peripheral_gatt_dm project. In that project, I enabled MCUBOOT which caused a linking issue that I temporarily resolved by setting CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP to 0. See devzone.nordicsemi.com/.../bug-in-ncs-v1-7-1-with-32khz-rc-oscillator-and-mcuboot-enabled as to the reason why I had to set CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0.
2) Add the following lines into the C:\ncs\v1.8.0\zephyr\boards\arm\nrf5340dk_nrf5340\nrf5340dk_nrf5340_cpunet_defconfig file:
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0
3) Use the following command to build and flash the image:
west build -p -b nrf5340dk_nrf5340_cpuapp
west flash --erase
4) In the app core side, you'll see the following console logs:

The k_sem_take failure is caused by the net core crashing.
I would like to know if there's a way to not have to set CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0 to fix the linking issue or is there a work-around to prevent this crash?
The crash only occurs with the Nordic Bluetoooth Controller. It does not crash with the Zephyr Bluetooth Controller.peripheral_gatt_dm.zip
Setting the CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=n or CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y instead of CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0 is not an option that I could use.
