Do I need to run the secure boot sample before running the asset tracker application for the nrf9160dk?If so where do I find the secure boot Cmake files.I can't find them in my samples folder.

SPM does not have anything with the application itself to do, SPM is a firmware that is required to set up the nRF9160 DK so that it can run user applications in the non-secure domain. See more here.

The board is still lacking the current Asset Tracker. Please follow this guide to get the correct version. Then update the modem with the latest FW using this file:
mfwnrf916007029alpha.zip

Kind regards,

Oh sorry, I meant guide by you(the link given by you).

Ah, sorry

Can you please exit Segger Embedded Studio, and delete every build folder in the Asset Tracker folder (nrf\applications\asset_tracker). Now follow this guide. 

Let me know how that works for you. 

Kind regards,

Øyvind
