Some question about tz

1. What does "cmse_check_adress_range" function return?

2. Using "__attribute__((cmse_nonsecure_entry))" means that after passing the parameters to caller function, the r0-r3 register immediately cleared by hareware?

When i was creating a project following AN291, i had some problems below:

1.After creating the "secure project", i didn't find the file "Test_s_CMSE_Lib.o" in the object file. I don't konw why. (please see the picture and the red rectangle)

2. And I wonder how can i find the "get filetype for 'Test_s_CMSE_Lib.o' " in the picture below?

AN291, page 14

Thanks a lot!
