I am using 1286 topboard with a sketch and i cannot get the current sketch to upload. I have correct port and board selected. The Industruino flashes like it is uploading computor beeps as if the usb has been unplugged during the upload. The Industrino comes back on with the old sketch and the new sketch never gives and errors but just sits on uploading and never completes. Any help would be much appreciated.
