Hi, I am having trouble with the uploading on my redboard, after uploading a program to the board I have to disconnect the board before I can upload anything else to the board. Having disconnecting the board it always work okay.

Is that with every sketch you upload ? Do you have additional hardware connected ? What happens with a very simple sketch with just a Serialprintln(" hallo");
