error: Aborting due to Kconfig warnings when adding out of tree sensor driver to nrf9160dk

[Liza]

Hi,

I am adding out of tree sensor driver (LDC2114) to nrf9160dk, I follow the Adding an Out-of-Tree sensor driver to Zephyr - Golioth. But when building the configuration, the CONFIG_XXX except CONFIG_LDC2114 in the prj.conf becomes undefined (There is no error before adding the drivers).

This is my whole project .

I haven't done the driver file ldc2114.c. I just want it build correctly first. It can build successfully without Kconfig, west.yml and drivers file. So I think something wrong in these files.

Best regards,

Liza

Hi Liza,

I am not able to download your project; clicking on it sends me to a broken link. This often happens if a file is uploaded to a post or reply that was later edited. Can you try uploading your project again in a new reply? Make sure not to edit the reply after sending it.

We have an exercise in the nRF Connect SDK Intermediate DevAcademy course that shows how to create a custom out-of-tree driver, so I recommend taking a look at it. You can find it here: Exercise 1 – Creating a custom driver using the sensor API.

Best regards,
Marte

Hi Liza,

You need to source the Kconfig.zephyr file in your project's Kconfig file (9160_ldc/Kconfig). You can do this by adding the following to the Kconfig file:

source "Kconfig.zephyr"
