Thank you very much.
It has definitely changed something.
But then I receive a very unspecific error message:
"An error occurred while uploading the sketch"
I get a more detailed error message when activating "Show verbose output during upload":
Using Port : COM10
Using Programmer : stk500
Overriding Baud Rate : 38400
avrdude: stk500v2_ReceiveMessage(): timeout
...
avrdude: stk500v2_getsync(): timeout communicating with programmer
I am sure the sanguinololu board is OK, because I can flash it flawlessly with the old Arduino/Marlin combination.
What seems strange is that programmer is set to "stk500", but the error message from the Arduino IDE mentions"stk500v2". Could this be the problem?
