Unable to interface CCS881 with nrf board : error : Failed to get device binding

[Aditya_s]

Hello,

I am trying to run the CCS881 sensor sample in my nrf9160 board. I have made changes to my project config file and main.c file as mentioned in 

https://devzone.nordicsemi.com/f/nordic-q-a/59834/nrf9160-with-ccs811-and-missing-log-in-lte-link-monitor, I am getting an error that my board failed to get the device binding.

I am using nRF Connect v3.4.1, Programmer v3.4.1 and LTE Link Monitor v3.4.1

My source code is from CCS811 example which I copied from  ncs\zephyr\samples\sensor\ccs811 to ncs\nrf\samples\nrf9160\ccs811. What could have caused this error and how can I rectify it?

Hello Simon,

The NCS tag is v1.2.0

Thank you for your response. My connections are as follows:

Vin     : 5v
GND,WAKE : Ground
SDA   : P0.11

SCL   : P0.12

This is how my overlay file looks like. Are connections okay?

&i2c2 {
status = "ok";
sda-pin = < 12 >;
scl-pin = < 11 >;
clock-frequency = <I2C_BITRATE_STANDARD>;

/* The I2C address could be one of two, here 0x5A is assumed */
ccs811@5A {
compatible = "ams,ccs811";
reg = <0x5A>;
label = "CCS811";
};
};

Try adding compatible = "nordic,nrf-twim"; to the overlay file:

&i2c2 {
    compatible = "nordic,nrf-twim"; //Add this
    status = "okay";
    sda-pin = < 12 >;
    scl-pin = < 11 >;
    clock-frequency = <I2C_BITRATE_S
    ..
    ..
    ..
}

If it still doesn't work, try to debug the init function to see if/what is failing.

Best regards,

Simon

I get this error while building the code:

Could you simply try to add the interrupts field like it's done here? Hmm.. I find it strange that the error comes up when it's set in the file nrf9160_common.dtsi. However, try to set it in the overlay file and see if the error goes away.

Best regards,

Simon
