A few weeks ago, we saw codebender, an online replacement for the Arduino IDE that allowed you to upload a sketch to your board from a web browser. Over on the codebender blog [Vasilis] and his team are rolling out a way to remotely upload code to an Arduino over Ethernet. Now you don’t even need a serial connection to program an Arduino; it can be done over the Internet to a board in the next room, or on another continent.
The star of this hack is the Ariadne bootloader, an implementation of TFTP that allows any Ethernet-enabled Arduino to receive updates over the Internet. There is still one small problem with the Ariadne bootloader: uploading code over Ethernet requires someone to press the reset button on the Arduino, completely negating the benefits of programming an Arduino over Ethernet.
This problem has been solved before for earlier Arduino boards, so we’re sure [Vasilis] and his team will be able to fix the reset issue in very short order. If you’d like to check out the remote TFTP bootloader and play around with codebender, you can grab Ariadne over on GitHub.
