RE: [ECOS] RE: Running a program from

["Trenton D. Adams" <tadams at theone dot dnsalias dot com>]

Is there documentation on editing these files?  I tried editing
target.ld, and it still doesn't work.  Do I have to do the
"-Wl,--entry=0xe0040000" as well?

In the SECTIONS part, I changed the following.
.rom_vectors   0xe0040000

I also tried changing
MEMORY
{
    ram : ORIGIN = 0, LENGTH = 0xfd7000
    sram : ORIGIN = 0x60000000, LENGTH = 0x9c00
    rom : ORIGIN = 0xe0040000, LENGTH = 0x800000
}

No, you'll have to edit either the .ldi file or the resulting target.ld.
eCos programs are linked at specific addresses in specific modes (RAM vs
ROM).  They aren't position nor mode independent - you have to adjust
things if you want them to move.
