Hi everybody,
I-m trying to flash an arduino using an UsbTinyISP. Everything worked fine til 2 weeks ago, while I started to get this error message
avrdude: verification error, first mismatch at byte 0x0080
0x04 != 0x10
avrdude: verification error; content mismatch
it happends trying to load any sketch, such as blink.
The only sketch wich the system is able to load is the empty sketch.
I'm running Arduino IDE 1.5.7 on Windows 7 x64. Tryed to change usbtinyisp drivers to x64 version but nothing changed.
I'm 100% sure the selected board is Arduino UNO (the chip is an atmega328p-pu) and the programmer setted is usbtinyisp.
Tryed to change arduino too, but keeps giving missmatch errors ... any idea ?
Thanks in advance for help
Uge
