I have burned the bootloader to the atmega644, the sanguino one.
It has ended with the message 'Done burning bootloader'.
-Using an Arduino as an AVR ISP (In-System Programmer):
Then i have tried to transfer a sketch to the atmega644.
-From Arduino to a Microcontroller on a Breadboard:
But i have get some error messages:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
The atmega644 has an extern 16mhz crystal.
