Hi,

I am observing that the nucleo_l552ze_q platform is producing hex files that overlap since the 1.5 release. Tested on master and 1.5.

Is there an STM maintainer that could look into this?

Steps to reproduce:

rm -rf cmake_build && cmake -S . -B cmake_build -DTFM_PLATFORM=stm/nucleo_l552ze_q -DTFM_TOOLCHAIN_FILE=toolchain_GNUARM.cmake -DCMAKE_BUILD_TYPE=MinSizeRel -DTEST_S=ON -DTEST_NS=ON && make -C cmake_build install && /usr/bin/python3.8 /home/sebo/ncs/zephyr/scripts/mergehex.py -o merged.hex $(find cmake_build -name "*.hex")

"/usr/bin/python3.8 /home/sebo/ncs/zephyr/scripts/mergehex.py" must be replaced with the preferred hex file merging tool.

output:

Traceback (most recent call last): File "/home/sebo/ncs/zephyr/scripts/mergehex.py", line 28, in merge_hex_files ih.merge(to_merge, overlap=overlap) File "/home/sebo/.local/lib/python3.8/site-packages/intelhex/__init__.py", line 875, in merge raise AddressOverlapError( intelhex.AddressOverlapError: Data overlapped at address 0xC014400

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "/home/sebo/ncs/zephyr/scripts/mergehex.py", line 56, in <module> main() File "/home/sebo/ncs/zephyr/scripts/mergehex.py", line 52, in main merge_hex_files(args.output, args.input_files, args.overlap) File "/home/sebo/ncs/zephyr/scripts/mergehex.py", line 30, in merge_hex_files raise AddressOverlapError("{} has merge issues".format(hex_file_path)) intelhex.AddressOverlapError: cmake_build/install/outputs/STM/NUCLEO_L552ZE_Q/tfm_s.hex has merge issues

PS: Depending on the revision tested, it might be necessary to also apply this patch:
