The USBtinyISP firmware simply doesn't support loading the
extended address information.

Should ladyada ever decide to update the firmware, she could
submit an updated AVRDUDE implementation file as well. Until
then, there's nothing we could do about it.

This is not an avrdude problem, it is a usbtiny restriction, see http://www.ladyada.net/make/usbtinyisp/faq.html


What chips can be programmed?

Any AVR that uses the ISP interface for programming and has 64K or less of flash can be programmed.

Chips such as the Atmega1280/1281 and Atmega2560/2561 have more than 64K and cannot be programmed

Chips that use TPI interface, such as Attiny4/5/9/10 cannot be programmed

Using a USBtinyISP with AT90USB1286, the memory above 0x10000 is getting read incorrectly with the -U flash:r/v commands.

It's easy to reproduce this. Try writing flash above 0x10000 and the verify will fail. Try dumping memory, and the contents above 0x10000 is always 0xFF
