HermannSW: I really like this solution and thought that soldering a normal 10k resistor would be easier than a SMD 0603 resistor. I tried for 10 minutes but was not able to get the 1st pin of the resistor firmly connected. Then I was not able to just get a blob of solder firm as described in the freetronic description. So I had to give up, will ask a colleague at work who is much better in soldering than I whether he can do that soldering of 10k resistor for me.
Here is an update, today my colleague helped me and soldered the SMD 103 resistor onto one of my 3 Arduino Dues:
I did flash "Blink" example program and after disconnecting and reconnecting power Due blinked again. This resolved my real need for Arduebot -- it would be really bad to have Arduebot robot driving some course and getting fully stopped by a voltage spike without any chance to restart.
Next I disconnected the USB cable, went to colleagues computer and connected there -- Due Blink program did NOT start.
After some investigations I can say the following on this 10K resistor fix for my Due:
- if power disconnect takes less than 4 seconds, blinking starts when reconnecting USB power
- if power disconnect takes 4 seconds or longer, Due does not start blinking
Can anybody explain this behavior?
