NVS in non secure application

Hi,

Good to hear that it solved the problem!

For the Debug Options, see the docs on Debugging an application.
This sets the two configurations CONFIG_DEBUG_OPTIMIZATIONS and CONFIG_DEBUG_THREAD_INFO.
If you look at these options, you can see which other options they select. Maybe some of these are messing with your application somehow?

You could try to only enable CONFIG_DEBUG_OPTIMIZATIONS manually, to see if it makes a difference.

Also try to use Ozone to debug, as it is usually better at debugging Threads than GDB.

Indeed, that solved the problem.

Why is that? I build the secure application also with enabled debug options.

Also I noticed that the option is changing the program flow a lot more than expected, the timing is different now (for example printk messages are now sent after the initial shell prompt, while with enabled debug options they were sent first).

I thought that the option is more or less neutral to the application, even as I am searching now I can not find a description of this effect.

Hi,

Do you have debug options enabled when you build?

I am able to build and flash it but it doesnt start, same sample with secure build runs as expected.

Are you able to build and run the NVS sample without changes for "nrf9160dk_nrf9160_ns"?
