There is also the use of arm-none-eabi-objcopy to create a .elf file out of a .bin

For instance : where I wanted to append a CRC to a linked binary .elf file

The CRC program wrote a 2 byte binary file prog_crc.bin based on the CRC of a part of the binary file using the linker map to locate where ...
