You have problems with programming if the ethernet shield is connected to the development board?
avrdude: stk500_recv(): programmer is not responding
The reason for this is not one hundred percent compatibility and in particular, the issue with the reset of the cpu right
before his programming. It's a pretty common thing and meet with her for more shieldů. The board is not defective and this is so out of principle. So how to do it?
Once in the Arduino IDE click on the icon "upload program" immediately after press the reset button on Your development board. The Program will then load without any problems.
If you are using the icon "compile + upload the program", keep in mind, that will take some time to compile the code. The reset button is pressed it is necessary to immediately after what data to send to the development board.
In a normal situation with a reset of the old automatically the Arduino IDE, but some of the shields serves, such as the ethernet shield, it can defend itself.
