Including A Raw Binary File Into A Linker Script

kackle123 — Tue, 30 Apr 2019 19:22:50 GMT

I am using CodeWarrior 10.6 (CW), with gcc, for a Kinetis project, with MQX 4. I want to include an external binary file from another project and have it linked into this project's output. I read a number of PDFs and forum posts, but I have found the following problems: In the linker script/command file (.ld), the INCLUDE command here means "include another .ld script", NOT "include a binary file". And, the commands TARGET and OUTPUT_FORMAT are NOT recognized by the linker (arm-none-eabi-gcc); they only cause syntax errors.

Is this possible in this environment?

If you want to do it with the linker, then there are many possible (maybe more) approaches:

- use a binary include in the as (assembler). This creates a object file you can link with

- use the objcopy to create an object file (See as well Converting a Raw Binary File into an ELF/Dwarf File for Loading and Debugging | MCU on Eclipse on that subject)

- see Include binary file with GNU ld linker script - Stack Overflow

I hope this helps,

Erich

I've been searching and trying so hard to get the linker commands to do what I want that I didn't even look for alternative ways. I'm sure that one of your suggestions will work since it seems the linker commands themselves fall short (despite the fact that the "MCU_Kinetis_Compiler.pdf" that came with the CW installation says "INCLUDE" handles binary files). Thank you. And let me say that it is an honor to have you reply to my inquiry; your MCU/Eclipse website has been helpful many times.
