I am having this configuration set in my arduino uno: Programming ATtiny84 / ATTiny44 with Arduino Uno
I have even uploaded the blink LED program(using arduino sketchbook) and it works great at 8 MHz. Now I am trying to add an external 12 MHz crystal. I tried burning my internal crystal by using the command mentioned below but stuck with this error.
D:\software\avrdude>avrdude -c arduino -p t44 -P COM7 -U lfuse:w:0x60:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0xe0
*update: I'm using arduino as ISP as my programmer
