HEX loading. I have selected the ATmega64 in device list but not able to connect to device is not reading device ID. ATmega64A is with default Setting of fuses. Its fresh chip. I have checked All connection. PEN is connected to ground. I am not able to understand what is going wrong ATmega64? Need your help if any one has faced such an issue before.
