I don't want the spm and application firmware built together so I tried using the "spm" sample in version 1.3 of the sdk. However when configuring the project it it isn't displaying the spm menu as it does when the spm is included with the other samples?
SPM is only in secure zone, so you'll only see its menuconfig.
A "regular" application will show its menconfig as well as SPM's menuconfig because all applications are built with SPM by default.
Please note that we're entering the summer vacation period here in Norway, so delays must be expected as we are low on staff for the month of July. Sorry about the inconvenience!
How do you configure the spm sample then?
Sorry, I think you misunderstood. You configure the SPM sample the same way you'd configure any other example, it's just that the SPM will exclusively be in secure "mode".
