Hi,
I am using nrf Connected SDK v2.6.2 on windows 10. I try to create a blank application project for the device ADXL363 on SPI2 bus on the nRF9160DK board.
I basically followed the sample here: https://github.com/aaron-mohtar-co/Lemon-IoT-LTE-nRF9160/tree/main/Examples/spi_sensor
The error message shown as below:

The blank application has no \dts directory. So, I created the binding file....
\dts\bindings\sensor\adi,adxl363.yaml

How can I define the ADXL363 devicetree via SPI2 properly?
