[Uisp-dev] downloading to atmega162

[Owen S. Osborn]

   I've been using uisp in dapa mode with a home brew cable, and this method 
has worked great with the atmega8 chip.  But while using this same method 
with the atmega162, uisp indicates that the chip is not responding and might 
be damaged.  (there is really no response as I probed the data out pin of the 
microcontroller with scope, and it is low during entire process).  I have 
double 
checked the wiring, and tried 5 different atmega162 chips, but none respond 
(i have also tried with and without external oscillator).  
   The strange thing is that with the same wiring the atmega8 responds while 
the 162 does not, and I can't find anyting in the datasheets indicating 
additional connections are needed.  I've also tried avrdude, and the problem 
is the same: atmega8 works, while atmega162 doesn't respond.
   Am I missing something here?, or could it be that all 5 chips I;ve tried are 
dead?  any help is greatly appreciated....

thanks
