How to use none secure example on nrf5340

[sean]

Hi，

I want to use none secure example on nrf5340.

The code can't run with ns config(uart didn't log anything),But it works fine with normal config.

How can I sovle this problem?

My ns configuration method is as follows

1.import project

2.set menuconfig

3.set spm_menuconfig

In step 3 you try to build the SMP for the non-secure partition and that is not possible, it has to reside in the secure partition otherwise it would not be secure.

I use west init -m https://github.com/NordicPlayground/fw-nrfconnect-nrf --mr v1.2.0    get the code of v1.2.0 .

I tried the third step ,set to nRF5340 DK nRF5340 Application MCU.But it still doesn't work.

If I import the project with nrf5340_dk_nrf5340_cpuapp, it works fine with log printed

Have you rebuilt with a "clean" build? 

There's probably a set of configs for the NS build still present.
