Follow-up Comment #2, patch #7184 (project avrdude): I discovered a bug in this patch and thought I would share. It appears that when writing to avr flash memory, the support code for pickit2 does not correctly compute the length of the final write sequence. As a result the final page commit never occurs. I'm not sure in what cases this was a problem, but it was causing my bootloader write operation to fail during verify. The last page of flash memory was always unwritten.
