The linker should output code/data placement and statistics in the .MAP file. This should allow you to identify what is happening and where the size is being accumulated from.

You have multiple non-contiguous memory regions, and the .BIN file is a singular file that must span these two regions and any space between them? No real specific detail to work from here.

Read the documentation for your tools, and consider texts on compilers and linkers, and functional expectations there.

I had the same problem, i checked the map file, i see no problem, when I change it to hex file, the size of the hex file seems to be OK.

A binary file is a literal dump of a memory region. It does not compress or skip regions, like a hex file.

If you create a binary for a STM32F1 for the 32 kB of flash, and you started at 0x0000, you'd have binary of 132 MB.

Check the linker to see which regions it's writing to the binary file.

(also, if you take two nonconsecutive regions, it will pad zeroes in between them)
