ads can't read the symbols in gcc produced elf files, adw crashes if you try and use it to download one. (or at least it did last time I tried it).

The best you can do with the gcc/adw combination is to build without symbols to generate a file that you can download. However, the lack of symbols makes it rather harder to debug your code once its on your target :-)

I think Lauterbach do a JTAG debugger which can load gcc elf files correctly. Or maybe its possible to get a gdb/jtag solution, but I don't know of one offhand.
