Argh ! 10 avrdude attempts in 1.6.4. How do I turn it back to 3 ???

Yes, I've looked. At preferences, and at avrdude.conf and googled

  • Why is the Arduino IDE 1.6.4 now trying 10 times to get sync instead of what it was (3 times)

  • Where can I set the number of attempts ?

avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x03
avrdude: stk500_recv(): programmer is not responding
