BME680 sensor sample not building #17876

Closed mrusme closed 5 years ago

mrusme commented 5 years ago

Describe the bug

The sensor sample for BME680 is not building as described here.

I solved this by copying the code into an own project, specifying the following definitions inside the CMakeLists and using cmake/ninja instead of west:

add_definitions(-DDT_INST_0_BOSCH_BME680_LABEL="BME680" -DDT_INST_0_BOSCH_BME680_BASE_ADDRESS=0x77 -DDT_INST_0_BOSCH_BME680_BUS_NAME="I2C_1" -DDT_BOSCH_BME680_BUS_I2C=1)

However, when running the build on the Nucleo board I still get this:

I searched the Zephyr code for possible values for these definitions but could not find any. Nor are they documented anywhere (or at least it's not obvious enough so that I could find it).

To Reproduce

Steps to reproduce the behavior:

  1. west build -p -b nucleo_l476rg samples/sensor/bme680

Expected behavior

The sample should build and the build should run.

@carlescufi maybe you could just point me into the right direction in regard of the defines I mentioned above, so that I know what values they should be set to in order for this to work, so I can figure it out on my own and in the best case set a PR to this repo? :)

Thanks a lot!

carlescufi commented 5 years ago

@mrusme you need to add a BME680 to your Device Tree file I believe. @jhn-nordic, @joakimtoe, @jtguggedal or @MaureenHelm can hopefully help you out here

mrusme commented 5 years ago

Thanks for the hint. I checked the documentation but did not see a way to extend the existing device tree for a board with a sensor that was additionally added over I2C (apart from creating a "new" board and including the sensor within the DTS maybe, although this might lead to having to back-merge all changes to the original board every time they occur?).

What is the best approach to take here?

Thanks a lot!

carlescufi commented 5 years ago

@mrusme the options you have are:

  1. Modify boards/arm/nucleo_l476rg/nucleo_l476rg.dts
  2. Add a nucleo_l476rg.overlay to your application with the BME680 node, as described here
  3. Define your own board (see here)
carlescufi commented 5 years ago

@mrusme if you solve the problem by adding the node to DT, can you close this issue?

mrusme commented 5 years ago

@carlescufi I guess this could be closed then, yes. I would re-open another issue, if something with the DT overlay would not work. Nevertheless it maybe should be documented somewhere. Let me fiddle around with it further, if I manage to get it working I'll set a PR with the changes to the docs.
