Hi,

Are you building from command-line( using west) or using Segger Embedded Studio ?

(Make sure that you put the SW5 in nRF91 position when you flash for the nRF9160).

In v0.4.0 the at_client sample will build spm for you when you use target board nrf9160_pca10090ns. The output from the build is a hex-file called merged.hex that contains both the at_client and the spm. So there is no longer any need to build spm project separately (previously known as "Secure_boot").

If you are using west, you can build and flash it like this:

west build -b nrf9160_pca10090ns -d build_folder
west flash -d build_folder

If you are using SES, then take a look at this post.
