I am trying to generate the elf.bin file from my project which generates elf.hex of size 8329KB where as when i try to generate the elf.bin output it generated of size 30,35,513KB, why is this a too large size, how do i reduce it so that i can use this binary in other application

Attached a screenshot for the generated output files.

Thanks in Advance

    By not using BIN.

    ELF, HEX or S19 have address specifiers, and don't need to dump-fill memory areas.

    BTW, this queston had already been answered several time here.

    A binary file is a single file, you clearly describe multiple memory regions to the linker, and these regions are separated by vast distances. Use a .HEX file it can better describe a sparse memory map.

    ​

    For example ​0x10000000 and 0x20000000 are 256MB apart.

    I'd take the .HEX file, or .ELF/AXF and package that into a compact binary form, based on my understanding of the memory map being used.

    ​

    Perhaps you should look at the .DFU format, and tools for generating them.​
