out of tree driver; builds, links but not in map

[Mike Pulice]

I have an out of tree driver (vl53l1x) building and linking for an out of tree board which works.  
However, another driver for bmi088, builds, appears to link but does not appear in the map files
which leads to this error when I try and use the sensor --> undefined reference to `__device_dts_ord_127' 

I have a feeling the dts fragment may be the cause but not sure at this point.

source tree looks like this 

- project_root
  - boards
  - dts
  - hello_world
    CMakeLists.txt
    KConfig
    prf.conf
    sample.yaml
  - drivers

Hi,

It seems something is not enabled, either in your device tree or Kconfig (prj.conf). I suggest you open your build folder and find this file: <build_folder>/zephyr/include/generated/devicetree_generated.h. There you see the numbered nodes. As you got __device_dts_ord_127, 127 is relevant here. That points to a peripheral or similar, and that needs to be enabled/included.

[Mike Pulice]

I forgot to mention I had already looked there and everything is defined as far as I can tell as compared to functioning devices. Please note that I added some PWM code to bring up that part of the board so my ordinals have changed.  
Since this chip has two addresses in it we can just look at the gyro which is ordinal 132 now.

I did not include property macros but they are there.  Based on what I see, there is no reason it wouldn't be included in the link.
