Arduino IDE w/2560 bootloader error with ArduinoISP
Today at 03:51 pm
Hi everyone,
I guess I had this posted in the wrong section so I'll try here.
I've been looking through a number of posts about bootloader problems and can't find anything which addresses my problem, so I hope someone out there can help.
I'm trying to get a new PCB layout with an ATmega2560 device up and running but I'm having problems getting the bootloader programmed. I bought an ArduinoISP and have that selected under programmer. When I select burn bootloader I get the following message:
Arduino: 1.6.0 (Windows XP), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"
avrdude: verification error, first mismatch at byte 0x3e000
0xff != 0x0d
avrdude: verification error; content mismatch
Error while burning bootloader.
I've scoped the pins while it's programming and can see activity on both the MOSI and MISO pins. Reset goes low and stays low during the whole process which is curious since it is only pulsed low for programming the normal firmware.
Just FYI, I tried the same setup on my Arduino 2560 board and basically turned it into a not so useful paperweight which means it most likely isn't a layout error. Any help is greatly appreciated.
Thanks.
