[avrdude-dev] [bug #41857] avr109 atmega2564rfr2 erase timeout to short

[Georg von Zengen]

Follow-up Comment #2, bug #41857 (project avrdude):

setting the timeout for the programmer will also increase the time for fault
detection for all AVRs.
The patch I attached implements a fourth idea.
For the butterfly chip erase function it takes the number of flash pages and
multiplies it with 10. If this is higher the the default timeout it is
applied.
For a chip with 1024 pages like the 2564rfr2 that means ~10s timeout.
I think a multiplier of 10 is a good value because it corresponds with my
observations and the 7.3ms - 8.9ms per page erase mentioned in the datasheet.
