RE: Another "undefined reference to __device_dts_ord_xx' linker error

Thank you. I missed that subtlety, and I was looking right at the example code in lesson 6 of the Intro to nRF SDK and still didn't see it.

Hi,

Apologies for the delayed response. Instead of using DEVICE_DT_GET(), you can use I2C_DT_SPEC_GET() to fetch the structure for a device on the I2C bus. For example:

static const struct i2c_dt_spec gnssI2C = I2C_DT_SPEC_GET(DT_NODELABEL(ubloxm10s));

DEVICE_DT_GET() is failing because there is no SDK driver associated with your sensor to initialize the device structure.

Best regards,

Vidar
