 ===== Android =====
+Because RK merged the logo partition with the system partition into a single super partition after Android 10, there is no logo partition available to dynamically modify the boot logo. This means that a complete firmware build is required to achieve this operation. Now, we have added a new custom partition to facilitate the dynamic update of the logo.
+==== Logo Format ====
 <WRAP info >
   *Where is original logo file
-Logo file is stored in the device/khadas/TARGET/logo_img_files/bootup.bmp directory in android code.
+Logo file is stored in the kernel-6.1/logo.bmp directory in android code.
   *BMP format, should be:
     *16bit RGB565 BMP format
   *Resolution <= 1080P (1920 * 1080)
-  *How To Change
-Replace the bootup.bmp ,then rebuild the logo.img
