I've got a setup with an ATMega32 running perfectly. When replacing the ATMega32 with a ATMega32A, nothing happens any more, not even the crystal oscilator swings. According to the changenote from Atmel, the reset pull-up resistor has a good value and the pull capacitors next to the crystal are also in place. I tried with many different parts (all from one shipment) of the ATMega32A, always the same behaviour. Changing back to the ATMega32 everything is fine again.
Finally I setup a circuit only with the AVR, reset pull-up, crystal and pull-capacitors. ATMega32 works (crystal swings), ATMega32A does not work (crystal swings not).
Could you think of anything but all ATMega32A I have in the lab are broken?
