To the best of my knowledge the avr patch for gdb4.18 is all there is at 
the moment.  Seem to recall Denis saying he was looking into writing a 
simulator but as yet I guess there hasn't been sufficient time available, 
after all he's maintaining the binutils and gcc avr ports already!

Without a simulator gdb can only be used with some debugging code in the 
AVR program, it uses the SPI port to communicate with a GNU/Linux 
machine.  I believe that AVR studio 4 will have elf support, but that 
doesn't help those of us who want gdb.  The latest AVR devices have JTAG 
debug/programming interfaces and should mean we can achieve real-time 
debugging in hardware without an emulator, a worthy goal would be to make 
this work with gdb.  Still would be nice if someone with some spare time 
would comit to writing an open simulator :) hint hint

gdb4.18 avr patch available from
http://home.overta.ru/~denisc/
Note there is a description on how to use it at

Denis, please correct me if i'm wrong.
