How to check that the "make writable memory non executable" function is working

OEM is doing design with Jeston Xavier NX, and wants to know how they can verify that the function to make writable memory non-executable is working.

hello riwilliams,

am not quite understand your request,
there’s $ pmap commands you might use to show the memory usage of a process.
please also check the processes PID by $ ps aux .

you might refer to Xavier TRM, please refer to chapter-3.4 System Memory Management Unit (SMMU);
please also check the wiki page about memory protection for more details.
