When I try to upload a sketch, I get the error:
avrdude: stk500_getsync(): not in sync: resp=0x00
Facts:
- It did work before.
- Using Arduino UNO R3 with ATMega328P-PU.
- Previously uploaded sketch still works.
- Other ATMega328P-PU chip with pre-loaded sketch also works in this Arduino.
- Arduino is recognised by PC.
- Trying to upload returns the error quoted above.
- Using Windows 7.
- Using Arduino 1.0.2 IDE.
- Trying to get to DFU mode by temporarily connecting GND and Reset on the connector near the USB port doesn't work. The Arduino stays in its 'normal' mode. Although I must admit that I wouldn't really know what to do next if it would have worked.
I learned that my ATMega16U2 chip might be broken, but maybe it could work again if I upload the firmware again to it.
I do have an AVRISP MKII, and I do have a second Arduino as well, so I want to attempt to do this.
Now I can't find out exactly how to use either device to attempt to revive my first Arduino. I've been searching quite a while, but I can't find any tutorials that explain this, except some global hints. Since I'm relatively new to this stuff, I'm afraid to plug in the MKII the wrong way and damage my Arduino even further.
