ok, so now Ive jumped into the actual source code for elf2flt.
It does appear that the elf2flt utility is rather old/obsolete, and it looks like it has pretty much been abandoned.. Perhaps youre right, and its going to be necessary to update elf2flt (I even read on some message list that someone gave up on it and created their own elf-flat converter...). Its going to be slow-going on my end, Im playing a large amount of catch-up on this, as Im pretty clueless on how most of this low-level stuff works.
the elf2flt source code is in the 'output/toolchain/elf2flt' folder
btw, there's an option for elf2flt for 'loading to ram', any idea what that could be used for, and if it could have something to do with these issues?
