NCS 2.0.0: sync_rtc.c:238: undefined reference to `__device_dts_ord_19'

My project builds fine in versions previous to 2.0.0.  However, in 2.0.0 I'm getting an undefined reference.  Any ideas where to look to track this one down?

/opt/nordic/ncs/toolchains/v2.0.0/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.bfd: zephyr/libzephyr.a(sync_rtc.c.obj): in function `mbox_rx_init':
/opt/nordic/ncs/v2.0.0/zephyr/soc/arm/nordic_nrf/nrf53/sync_rtc.c:238: undefined reference to `__device_dts_ord_19'

Let me retract this issue.  This was due to a change I made in the configuration at the same time as updating to 2.0.0.  I've fixed that.

Do you remember the problematic configuration? I have the same error.

in function `sync_rtc_setup':
...zephyr/soc/arm/nordic_nrf/nrf53/sync_rtc.c:266: undefined reference to `__device_dts_ord_18'

If I remember correctly, it had to do with disabling the console uart for my custom board.

Actually, I had to add the following to my prj.conf for NCS 2.0.0:

CONFIG_NRF53_SYNC_RTC=n

Hi Denis, thank you for updating the case and sharing your findings.
