I keep getting the 'input file contains no relocation info' message ... which I guess is correct as the elf file has been fully linked, so maybe I can't use this utility for what I need ...

Using elf2flt on any old executable doesn't really make sense.  Unless
the code is entire pic code and pic data,  you cannot create a working
flat file without relocation information.

> Essentially, I'd like to be able to analyse the various sections of the executable but have a simpler format than elf so this is the main reason for looking at mb-elf2flt. I used mb-objcopy to get a binary file but as this removes any information related to the structure of the executable I thought I'd try elf2flt.

I would use size, objdump and objcopy to analyse binaries.  They have
more options than elf2flt will ever provide :-)
