Combine boot loader and app into one .out file

Other Parts Discussed in Thread: TM4C129ENCPDT

I am needing to combine two different .out files into a single combined .out file.

My target device is a TM4C129ENCPDT and I am trying to combine boot loader (boot.out) with my application (app.out) so that it can be programmed from a single .out file.

The boot loader resides at the base of flash, and the application starts at an offset above the boot loader.  

I intend to use "LM Flash Programmer" to program the device over Ethernet.  This method erases all of flash memory so reprogramming the application results in the boot loader being erased.  

I want to combine the two .out files into a single file that will reprogram the boot loader and application at the same time.

Thanks, Troy

    Thank you George.

    I have read through that article and they using "hex470" to combine the .out files into a .obj file.

    In my case using theTM4C129ENCPDT I assume the tool would be "armhex" not "hex470"

    Also will the LM Flash Programmer be happy with a .obj file, or will this require another layer of conversion back into an ".out" or ".bin" file?

    Correct.

    I don't know.  I am not familiar with any flash programmer.  If it can accept an .out file, then I expect it can also accept an .obj file.  But I'm not certain.

    Thanks and regards,
