Static Library Problem

[mateusz-]

Describe the bug

Hello,

I built a couple of different libraries and statically compiled them. My CMakeLists.txt looks like this:

cmake_minimum_required(VERSION 3.20.0)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(littlefs)

FILE(GLOB app_sources src/*.c)
target_sources(app PRIVATE ${app_sources})

target_link_libraries(app PUBLIC
    ${CMAKE_SOURCE_DIR}/libxlsxio_write.a
    ${CMAKE_SOURCE_DIR}/libminizip.a
    ${CMAKE_SOURCE_DIR}/libz.a
    ${CMAKE_SOURCE_DIR}/libbz2.a
)

The project builds fine. If I run the project, I get a fault. This appears to happen if I call one of the functions from the libxlsxio_write.a. Disassembly view shows me something like:

xlsxiowrite_get_version_string
reset.S.obj
{
 00000210   ADD            SP, SP, #16
 00000212   B              0xFFFFFC70                    ; <__longjmp_from_arm>+0xFFFE2290

At 0xFFFFFC70 there's an NOP instruction, and everything that follows is NOP as well.

The last step during the build process looks like this:

Where am I going wrong? The other libraries seem to behave the same. I built them using the same Zephyr toolchain as the application code.

I'm using nRF52833.
