Missing binding for out-of-tree driver

RE: Missing binding for out-of-tree driver

There is a additional repository that is much simpler than the NRFconnect_out-of-tree_example but shows the same problem. See NordicDTSgpioExample. Read the README.rst to build.

Change to compatible = "valve" in the overlay file to generate the error.

Finally the problem is solved:

The valve.yaml has to be placed (out-of-tree-project)\dts\bindings

Another improvement is not to use a costume board but define nrf52dk_nrf52832.overlay and compile with west build -p -b nrf52dk_nrf52832 --build-dir build. The nrf52dk_nrf52832.overlay is placed in (out-of-tree-project)\boards

The issue is still open and need an answer. So I made some additional tests.

My custom boards is still out of tree in ./boards/arm/test_nrf52832

I copied the gpio-leds.yaml and placed a valve.yaml in the same directory.

/dts-v1/;
#include <nordic/nrf52832_qfaa.dtsi>
#include <dt-bindings/gpio/gpio.h>

/ {

model = "Some readable text";
compatible = "test,test_nrf52832,nordic";

.... only part of the test_nrf52832.dts file

led {
compatible = "gpio-leds";
port06: _P06 {
label = "Signal LED";
gpios = <&gpio0 6 GPIO_ACTIVE_LOW>;
};
};

valve {
//compatible = "gpio-leds"; // HACK that works
compatible = "valve";

port020: _P020 {
label = "Valve auf";
gpios = <&gpio0 20 GPIO_ACTIVE_LOW>;
};
port08: _P08 {
label = "Valve zu";
gpios = <&gpio0 8 GPIO_ACTIVE_LOW>;
};

aliases {
auf = &port020;
zu = &port08;
signal-led = &port06;
};

};

The error I get seems to be in divicetree_unfixed.h. I suspect the gpio0 that is defined in the nrf52832.dtsi is not linked.

comparing the signal-led and the "Valve zu" the gpio0 part is not generated:

#define DT_N_S_valve_P_compatible_LEN 1
#define DT_N_S_valve_P_compatible_EXISTS 1

Any idea what is missing so that the valve binding is incomplete.

Thanks for help.

Sorry for the delay. Holidays are over now and I am at work again.

Please see the content of the buildall.bat below. The path that have to be modified for your installations are in blue.

Thanks for help

Where can I find buildall.bat? What are you referring to specifically by "some paths"? Is there anything else I need to know before I try to build?

I build to test_bt_nrf52832. It is a copy of nrf52dk_nrf52832 with some modifications for the TOF sensor.

The buildall.bat can be used for build with WEST but some paths have to be changed for your local installation.

Hello,

what NCS tag is this? What board are you building for?
