ATmega162V and STK500 kit

Hello, All!

    I'm trying to program ATmega162V chip using AVR Studio 4. STK500 board 
is installed according to manual and i can program the sample chip provided 
with board without any errors or warning,  but trying to burn the mega162v i 
get this error:

FLASH contents differs from file

Before burning I erased chip succesfully.  Oscillator frequency and voltage 
value are setup by AVR studio, I didn't change them.

What's wrong?

With best regards, Roman Mashak.  E-mail: mrv@tusur.ru

Go to the 'Board' page and lower the Oscillator frequency to 1MHz. The
default setting of AVR Studio is approx. 4MHz which is too high for a
mega162, which has it's internal 1MHz clock selected from factory.
