To program the MCU with Arduino I want to use an ISP programmer. The programmer works fine with Arduino (tested with original Mega2560) and the programmer works fine with the mega2560V on my custom PCB (tested with AVR Studio 6).
I now need to get Arduino to understand how to program the 2560V.
I found a board from Sparkfun with Arduino files but had no luck trying to program the MCU. No matter what I do (pick the original Mega, changing clock speed to 8MHz) or using the Sparkfun files ... I can not make the MCU to run a program (blink a led).
Is there anything I need to know? How can I make Arduino compatible with the Mega2560V?
So actually I don't want to upload using serial/USB programming - I am fine with my ISP programmer. But this just doesn't seem to work at all
Are you using "upload using programmer"? What programmer to you have, exactly?
Does "verbose output" from your upload attempt show a reasonable avrdude command? What error does it report?
Do you have one of those programmers that needs different firmware and/or drivers loaded depending on whether you're talking to it with Atmel Studio or avrdude?
Can you get avrdude to talk to your progammer from a command line? Can you manually issue commands that manipulate the 2560V?
yes - I use "Upload using programmer". No error message. The upload itself just works fine.
I use a Diamex USB programmer. The programmer works fine with Mega328P and Arduino. It also works fine with AVR Studio 6 and Mega2560V. So it's not an issue with the programmer.
I think it's a question of the Mega2560V specification at Arduino IDE or the bootloader (even if I don't use the bootloader really).
I think I need files that will tell Arduino how to compile and program the 2560V that is running with 8MHz and 3.3V.
