Can I blow away the bootloader on an Arduino board and use the micro with a JTAG ICE and AVRStudio? I need a carrier/proto board for the ATmega1280 and the ArduinoMEGA looks good.
Thanks,

Definitely. That’s no problem at all.

Cool. Thanks for the reply.
I’ve since found that not ALL the pins are routed on the ArduinoMega so…I’ll probably go with something else. At least now I know the Arduino variants are an option.
Thanks again,

Silly question, but you asked for it :): What do you need the other pins for? Most if not all of the important ones have been made accessible… Just curious…

A parallel data bus with another ATmega1280 and an expansion port.
A perfect use for the not so important I/O.

Well, thanks for the enlightenment!
You could get Seeedstudio’s Mega clone - it breaks out the missing pins.
Cheaper too.
I decided to go this route:

Gives me all pins. I don’t need the extras (usb interface, regulator, ect…).
The Seeedstudio Mega was runner up.

IMO: don’t buy Mikro E’s software. To say it’s buggy is an understatement.
I have one of these low-end JTAGs. Works fine w/Studio

I think NKC is a SFE partner

Thanks for the heads up. I’ll be using Atmels JTAG ICE and ISSP with AVRStudio. This particular project requires that I use the Codevision compiler.
