Issue with Mighty 1284P Optiboot bootloader on STK500

[wandrson]

I have been playing with a 1284p chip and have a little trouble getting it to work with the core from https://github.com/maniacbug/mighty-1284p/zipball/master

I have the chip on a STK500 and used a standard c program to verify that its fuse are correct and that it works. I then burned the Tools > Board > Mighty 1284p 16MHz using Optiboot bootloader and was unable to get the IDE to upload to the chip. I would get the following error:

Code:

avrdude done. Thank you.

However if I choose the other bootloader (Tools > Board > Original Mighty 1284p 16MHz) The process works fine. Not sure what is causing the problem with the Optiboot based bootloader, and if I can help debug, please provide guidance!

Oh, and even though the chip is running on a STK500, I am using a AVR ISP MK II to do the actual programming of the bootloader.
