_______________________________________________________
Details:
The new avrdude will attempt the upload several times, but apparently the
arduino-specific code to toggle DTR (and perform auto-reset) is outside of the
retry loop, which means that the board is not reset before each try. On
Optiboot-based boards like Uno, which have a one-second bootloader timeout,
this will mean that the board has long-since run the application.
On the other hand, sometimes the retries are quick (wrong response, rather
than no response?), perhaps giving the host time to flush buffered data or
noise, which might be effective...
