Like many I recently bought two atmega328 without bootloaders. All I have is an arduino ethernet shield, a usb2serial adapter, and an arduino rev2, is it possible to burn the bootloader with any of this items? Maybe through the usb2serial or ethernet shields icsp.
I would really appreciate some help. I have tried many solutions proposed by arduino, but none of them had worked. I still get this message:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
If you could provide step to step instructions it would really get me started.
