- | The command, showlogo is as following. | ||
- | <code> | ||
- | osd open | ||
- | osd clear | ||
- | vout output ${outputmode} | ||

- | ===== Using FASTBOOT ===== | ||
- | The logo partition is internally assigned in **U-boot** itself, please refer [[http://odroid.com/dokuwiki/doku.php?id=en:c2_partition_table#android_partition_table|this]] for detail. This works just for **Android Users**. | ||
- | Firstly, you must get into your **U-boot** command line while pressing any key when your **ODROID-C2** is powered up. And execute **fastboot** command from **U-boot** and connect with your desktop using USB cable. | ||
- | <code> | ||
- | odroidc2#fastboot | ||
- | </code> | ||
