40e7ed9427SCristian Maglie  2. Add this URL `http://downloads.arduino.cc/Hourly/samd/package_samd-hourly-build_index.json` in the **Additional Boards Manager URLs** field, and click OK.
41e7ed9427SCristian Maglie  3. Open the **Boards Manager** (menu Tools->Board->Board Manager...)
42e7ed9427SCristian Maglie  4. Install **Arduino SAMD core - Hourly build**
43e7ed9427SCristian Maglie  5. Select one of the boards under **SAMD Hourly build XX** in Tools->Board menu
44e7ed9427SCristian Maglie  6. Compile/Upload as usual
