I am trying to test a BME280 sensor on the nRF9160. I followed the steps where I created a folder (board) and added the nrf9160_pca10090.overlay and add couple of line in the prj.conf. I am building with build -b nrf9160_pca10090ns(non-secure). I get an error while building. I didnt connect the sensor but the code should build without the sensor am I wrong ?
same error with segger

I will add the codes form the files as well to make it easier.
