Re: [avr-gcc-list] Boot loaders

Yeah, I forgot about the linker script modification.  Yuk.  I wish there was a 
more
straightforward way to do this than hacking the system scripts.  Now to dig 
around the
archives and find that email detailing how to do this.

Thanks for the reminder.

I reviewed what I am trying to do and I think keeping the vector tables where 
they
default to makes sense.  My boot code won't use interrupts - just hard loops & 
polling
for data.  If I change my mind, it is easy enough to put in a partial vector 
table at
the beginning of my boot code.
