Hi

I have a code previously can be built in NCS 2.91:

However, when I use the new NCS 3.01, it can not be built, the error is:

Could you please help me figure out the problems?

Hi,

There can be some changes between these major NCS versions. I would recommend having a look at the changelog. 

undefined reference to `__device_dts_ord_112' typically means that there is something lacking in the dts file. What is new in DTS in NCS 3 is among other things that 

• Device tree and driver initialization ordering has become stricter.
• Some device tree nodes or aliases may have changed.
• Kconfig options or shield/board overlays may need updates.

It is hard immediately to say exactly what is at fault though.

Regards,

THank you so much! I just realized I should delete 

CONFIG_BT_LL_SOFTDEVICE=n

Thank you so much, happy weekend!
