Hi,
I am developing a project that uses TF-M to run some functions from a secure partition. The structure of the project is shown below:
├── lib
│ ├── ...
│ ├── blst.h
│ ├── libblst.a
├── mycli
│ ├── CMakeLists.txt
│ ├── README.rst
│ ├── prj.conf
│ ├── sample.yaml
│ └── src
│ ├── main.c
│ ├── secure_partition_interface.c
│ └── secure_partition_interface.h
└── secure_partition
├── CMakeLists.txt
├── README.md
├── secure_partition.c
├── tfm_manifest_list.yaml.in
└── tfm_secure_partition.yaml
I need to import a static library whose functions I am going to use only from the secure partition. Therefore, I intend to import them into the safe partition.
To use its functions, I include the library in the file I use it:
#include "blst.h"
If I use its functions, it tells me that they are not defined. I understand that it is because I have not included them in secure_partition/CMakeLists.txt. To include them, I write the following configuration in that file:
target_include_directories(tfm_app_rot_partition_sp PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../lib)
target_link_libraries(tfm_app_rot_partition_sp
PRIVATE
${CMAKE_CURRENT_SOURCE_DIR}/../lib/libblst.a
)
I don't know if I am doing something wrong when I include the library or if I just need more space. If I am doing the import wrong, I would like to know how to fix it. If I need more space, I would like to know how to get it, either by decreasing the size of my secure partition, or by increasing the size of the flash memory dedicated to it (the libblst.a file size is about 110 kB).
Regards,
Pablo
Useful information about the project:
- I'm using the nRF5340DK development kit.
- nRF SDK v2.0.0
- The project is based on the example: TF-M Secure Partition Sample. When doing the build for this example, the available and used space shown is as follows:
Memory region Used Size Region Size %age Used
FLASH: 21648 B 736 KB 2.87%
SRAM: 4816 B 256 KB 1.84%
