I've uploaded the Ariadne bootloader on an Arduino UNO compatible board using another UNO as ISP (I've followed this instructions). Apparently everything has gone well but when I try to upload a sketch on the Arduino UNO with Ariadne It's displayed the "programmer is not responding" error. The Ariadne bootloader can be used to upload sketches with the USB cable, right? I was wondering if I have to select a different board than "Arduino UNO" as I do normally, should I select the "Arduino UNO" choice under the sub-menu "Ariadne Bootloader" of Tools>Board? Tips are welcome. Thanks.
