Re: [avr-gcc-list] atmega128

Yeah, until I read the following in the ATmega323 datasheet - recent post 
on atmels web site (and I assume it will also apply to the mega128):

"The on-chip debug support is considered being private JTAG instructions, 
and distributed within ATMEL and to selected 3rd party vendors only."

Looks like another STK500 protocol episode, i've almost finished reverse 
engineering that one - guess the JTAG debug instructions will be next if we 
want to use open tools.  gdb would be very nice with a real debug interface 
to the micro, no more costly emulators.  Wouldn't it be nice if these 
people wouldn't force us to turn their product upside down and shake it 
until the secrets fall out, what do they gain?

Cheers,
