I am using bot original Arduino Due as well as Iteaduino due.
I have noticed that Iteaduino does not reset when connecting to programming port ( as it supposed to)
Small debugging and schematics review showed that it is … design mistake ??
The reset line from 16U2 is connected to NRSTB through 10k resistor - while the pin itself has 15k pullup. So it is not enough for reliable reset and you have to reset manually or turn off power.
Somebody can confirm that I got it right ?
