…M data The Zephyr linker scripts have inconsistent ordering of various chunks of data which lands in RAM at runtime. This leads to the value of _end not being consistently defined as the maximum address of static variables used in the application. Create a helper linker fragment, zephyr/linker/ram-end.ld, which can be included after the last possible definition of RAM data, that consistently sets _image_ram_end, _end and z_mapped_end. Signed-off-by: Keith Packard <[email protected]>
The generated scripts don't include a definition for any symbol indicating the end of statically allocated memory (such as "_end"). Add a shared cmake fragment, ram-end.cmake, which contains the necessary instructions to define _end and z_mapped_end consistently to align with the other sample linker scripts.
