Re: ROMable application with gnuh8-elf toolchain

[Bill Gatliff <bgat at billgatliff dot com>]

Stefan:

You don't need to rebuild your toolchain, you can use objcopy to copy 
your ELF file to COFF.

Many of the ELF linker sections are for compatibility with other 
toolchains, debugging information, and/or ABIs that you may not be 
using.  Start with the linker sections you recognize, and add in others 
as you get unresolved symbols or things look broken.  You'll find that 
you don't need most of them.
