VL53L1X - Custom driver not found

[Alskandar]

Hi,

I'm trying to set up a custom driver for the VL53L1X Sensor. (nRF9160 + Icarus Board + NCS 1.7.1)

I placed a new folder in drivers/sensor + modify CmakeLists.fr & Kconfig files.

However when i perform a build with VSC, it does not seem to find and put the driver on application. (I can't init my sensor -> VL53L1X not found)

After debugging, i see in build/include/autoconf.h file, there is no trace of my call to CONFIG_VL53L1X (CONFIG_VL53L1X=y in prj.conf).

If i do exactly the same procedure with de VL53L0X driver (already in drivers/sensor), no problem, everything works (CONFIG_VL53L1X is present in autoconf, all is ok, sensor detected).

When adding a custom driver, do any special handling have to be done ?

Thanks

I was trying the same thing with a different sensor.  The sensor would never show up on the Device list when I debugged the load devices.  Also the Driver init was never called by the OS.

What you are saying sheds some more light on this problem.

Hi 

Any chance you can zip the driver files, and the changes you made to the CMakeLists and Kconfig files, so I can try to build it here?

Best regards

Yes, here are the files

Hi 

It seems the best overview of the process of making a custom driver we have at the moment is an answer from one of my colleagues, available here.

Can you look over those steps and make sure you have followed them all?

If you still can't figure out the issue just let me know, and I will take a look at it (if you can also share your files that would be helpful). 

Best regards
Torbjørn

Thanks, this is what I did and sent in the zip.
In zip:
Kconfig & Cmakelists added in zephyr/drivers
In Application, this my project (the sub folder).
st,vl53l1x.yaml added in dts/bindings/sensor/vl53l1x
And folder vl53l1x added in zephyr/drivers/sensor
