Hi.

I finally solved it by using spm_request_random_number_nse instead of spm_request_random_number.

If it wasn't possible to use that function, is there another way to obtain a random number in the SPM module using a different function?

Thanks.

Hi.

I just edited the message because I think I figured it out, but I got that new problem.

Thanks for your answer and support with that though.

Hi!

As I said in my comment to you on the blog post, there is no way to use variables located in the non-secure side from the secure-side.

You will have to define the variables in the secure side and create a non-secure callable function to be able to read the variables from the non-secure region.
