Minimal example for linking static libraries within TFM using Zephyr

[StefanHri]

Hi,

For my project I need to link two static libraries one in the non-secure world and one in the secure world i.e., in a TFM Partition. I am using NRF9160.
Basically what I am looking for is extending the tfm_secure_partition sample with linking of static libraries.

Can you provide a minimal example code for that?

We do not have such a sample, and I can not write such a sample for you.

However, I can help you write such a sample.

The External Library shows you how you can both create and link a static library to your application.
I suggest that you start by adding a static library to your non-secure world.

Then you can take what you learned from that and add a static library to the secure world after.
In this case, you would need to add it to secure_peripheral_partition/CMakeLists.txt.
