 ====== How to change U-boot configuration by BOOT.INI ======

-In order to support easy boot loader setup, ODROID-C2 also support **boot.ini** as well as previous ODROID boards. So you can easily list up the commands what you want to executed in U-boot rather than the default. Here is the example to boot Ubuntu.

 ===== U-boot commands =====
 You can describe multiple commands of U-boot from the next line of **ODROIDC2-UBOOT-CONFIG**. The commands are only restricted within the commands enabled by the running U-boot.
 ====== How to replace booting logo ======
-**ODROID-C2** can shows booting logo to the display till target O/S is started.
+**ODROID-C2** can show booting logo on the display till target O/S is started.
-===== LOGO file format =====
-Currently, we support **24-bit Windows BMP image** and **24-bit Windows Gzipped BMP image**.
+Please refer to the following wiki page.
-And default size is **1280x720**. You can display any other size of logo file, but it will be showen at the left-top corner.
-===== Using BOOT.INI =====
+http://odroid.com/dokuwiki/doku.php?id=en:c2_bootlogo
-You can add the commands to your **boot.ini** before **bootcmd** is executed. Note that you can replace the logo file name **boot-logo.bmp** or **boot-logo.bmp.gz** with yours and it must be in FAT (BOOT) partition.
-<code>
-showlogo ${hdmimode}
-</code>
-The command, showlogo is as following.
-<code>
-osd open
-osd clear
-vout output ${outputmode}
-hdmitx output ${outputmode}
-fatload mmc 0 ${bootlogo_addr} boot-logo.bmp.gz
-bmp display ${bootlogo_addr}
-</code>
-===== Using FASTBOOT =====
-The logo partition is internally assigned in **U-boot** itself, please refer [[http://odroid.com/dokuwiki/doku.php?id=en:c2_partition_table#android_partition_table|this]] for detail. This works just for **Android Users**.
-Firstly, you must get into your **U-boot** command line while pressing any key when your **ODROID-C2** is powered up. And execute **fastboot** command from **U-boot** and connect with your desktop using USB cable.
-<code>
-odroidc2#fastboot
-</code>
-Next, run **fastboot** command from your desktop.
-<code>
-$ fastboot flash logo boot-logo.bmp.gz
