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.

Hello,

Secure Boot has now been renamed to SPM. What tutorial are you following? 

Please follow the Getting started Assistant in nRF Connect for Desktop. (Not the same as nRF Connect SDK (NCS)) After installing, please start the program and click "Add/Remove Apps". This menu will allow you to add the "Getting Started Assistant (v0.9.2)". Following the assistant will ensure that you have the latest version of NCS.

When compiling using the latest version NCS, both SPM and the sample you want to program are combined into one .hex (multi-image) file that you can program. See this link for more information information. Be aware that Segger Embedded Studio 4.16 does not support debugging multi-image projects, 

Kind regards,
Øyvind

is this the one?

I have been working on this from last 10 days but nothing is working.The SPM code also does't help.

[Øyvind]

Yes, that's correct! Have you followed this from start to end? 

[mayur_ch]

Yes, I have done that.Can you please tell what should I do ? After running the SPM program I have attached the screenshot above.I am getting errors in asset tracker too.

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:
