Firstly makebin defaults to a max of 32K (no idea why, I think it's just
written to wind people up) so do
makebin -s 65535
Secondly the linker has a weird and totally undocumented way of ordering
areas, which is that they are ordered by first mention. Thus you often
need your crt0 to start with something like
.AREA _BOOT
.AREA _CODE
.AREA _INITIALIZED
etc
in the order you need to pack things so you don't find your code
somewhere above 0xC000 or similar.
Also makebin
