How to relocate a NOINIT section?

[dennisjw]

Hi
Has anyone tried to relocate a NOINIT section? My understanding from the Zephyr doc, this is support:

If the memory type is appended with _DATA, _TEXT, _RODATA, _BSS or _NOINIT, only the selected memory is placed in the required memory region.

I have marked the variables with noinit similar to this example. I don't see corresponding changes required in CMakeLists.txt or linker script, so I am assuming I just need to specify what files will go into NOINIT section like this
zephyr_code_relocate(FILES ${reloc_files} LOCATION SRAM2_NOINIT)

However, I am facing compilation error like this:

code_relocation.c --default_ram_region RAM
Traceback (most recent call last):
File "zephyr/zephyr_rtos/v3.7.0/zephyr/zephyr/zephyr/scripts/build/gen_relocate_app.py", line 621, in
main()
File "zephyr/zephyr_rtos/v3.7.0/zephyr/zephyr/zephyr/scripts/build/gen_relocate_app.py", line 601, in main
sections_by_category = assign_to_correct_mem_region(memory_type, full_list_of_sections)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

mpu_align[memory_region] = int(align_size)
^^^^^^^^^^^^^^^
ValueError: invalid literal for int() with base 10: 'NOINIT|COPY'
ninja: build stopped: subcommand failed.

Does anyone might have some insight on what I am missing?
