I am using an ArduinoISP external programmer to upload a sketch to an Arduino MEGA.
I set the processor type to MEGA 2560, and use Ctrl-Shft-U to upload using a programmer. My programmer is set to ArduinoISP under tools>Programmer.
So far, I haven't been able to get the sketch to upload without a verification error. Worse, the programmer made it far enough in the upload process to overwrite the bootloader. Trying to re-upload the boot loader ("Burn Bootloader") also fails. The verbose error output is below with the exact error at the bottom.
A previous post suggested that code with a lot of 0xFF statements in it would fail. I have none.
Following a suggestion in the comments, I unsoldered the power over ISP programmer jumper (SJVCC) on my ArduinoISP. I powered the Arduino using the power jack; however, I got the same verification error.
I have also tried updating the software the the latest version (1.6.12), but that also does not seem to work. I may try to downgrade the software, but this all seems a little futile. Other forums don't seem to have a good answer for similar verification problems.
Is this a known problem? What can I do to fix it? What is particularly frustrating is that the problem occurs intermittently, ocassional after a computer reboot, it will upload successfully one time.
