Secure vs Non-Secure Build (NRF9160, ZephyrOS)

[phipi]

Can someone point me to where I can find some information about the secure vs non-secure builds and what considerations are required for either? Currently I'm trying to create an out of tree build for a custom board without modifying the nrfConnect repo but am running into spl.c build errors related to this in the boilerplate.cmake file.

if(${BOARD} STREQUAL nrf9160_pca10090ns)
    set(BOARD nrf9160_pca10090)
    message("Changed board to secure nrf9160_pca10090 (NOT NS)")
endif()

Hi.

I highly recommend that you take a look at the getting started tutorial for NCS, secure vs non-secure is also described there.

Best regards,

Here is a working link: 1.6 Secure vs. nonsecure
