FYI

https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/1807

Is on the way in now, which makes the watchdog available from non-secure by default.

Hi.

Have you set up the SPM to configure the WDT as non-secure?

I recommend you do it by adding a configuration file for the SPM in your project directory.

You can do this by adding the following to your CMakeLists.txt before you include :

set(spm_CONF_FILE
    ${CMAKE_CURRENT_SOURCE_DIR}/spm.conf
    )

And adding a file called spm.conf in your project directory (next to your CMakeLists.txt) containing:

CONFIG_SPM_NRF_WDT_NS=y

If you are using SES, remember that you have to re-open your project for changes in CMakeLists.txt and configuration files to take effect.

Best regards,

Didrik
