I think this bug is fixed by patch #3277 which was just committed.

Okay, the problems I experienced on non-interactive downloads were due to failure in avr910_paged_write_flash() to re-set the address correctly after page writes. That function has a several other problems:

- no polling or delay after page writes;
- no page writes when not using auto-increment;
- an extraneous page write when data ends on page boundary.

I'll submit a patch fixing all of the above.

The mess I observed in interactive mode is another story: avr910_write_byte() simply doesn't know at all how to handle paged memory. Ugh.

I'm getting very bizarre faults on writing flash, looks like either buggy avr910 driver code or timing problems - see the attached file for a detailed description. Hardware works fine with AVRprog.exe, host and target work fine with avrdude and an avrisp programmer, so the bug must be specific to avrdude's avr910 code.
