Topic: I need help with 2560 programming (Read 899 times) previous topic - next topic


I' used my USBASP adapter in ISP pins of board, using Arduino 1.0.3 to program 2560 chip.

At the end of programming with Arduino I got this message:
Binary sketch size: 203.542 bytes (of a 258.048 byte maximum)
avrdude: verification error, first mismatch at byte 0x0000
0x0c != 0xff
avrdude: verification error; content mismatch

Can you help me put this back to life?



I still cannot find out how to program 2560 with USBASP... I really need help.


Try bootloader from Nick Gammon http://www.gammon.com.au/forum/?id=11635, you need another UNO board, and check this topic http://arduino.cc/forum/index.php/topic,160988.0.html as well



The USBasp programmers do not properly support the large memory space of the mega2560.  However, others have just ignored the verification errors and said it still works.

Does you sketch run or not?
