Is there a clever way to properly set the value of interrupt vector 14
to the 2's complement sum of the other vectors, using either the GNU
linker or assembler?  I.e., create an image that is ready-to-go in terms
of passing the boot loader's signature verification?

Thanks,

Doesn't your downloader do this for you?

James,

You are using our debugger - right?

This should be done automatically when flashing using Seehau. Any problems?

Or is there any other things that I need to be aware of? Such as - is this
done for production, rather than debug?

Would it be acceptable to do it on an intel hex file (or similar simple
format)?

This all works fine in seehau..

I'm trying to put together a process to build production code, to be
loaded through the serial port during manufacturing.  I don't think the
on-chip bootloader will do this.

Maybe not, but the serial downloaders I know of do that for you, including 
(i believe) LPC21isp which has source available.

I just checked LPC21ISP source and it does this as part of the download.
