+ | Here is the sample bmp file. | ||
+ | {{:en:boot-logo.bmp.gz|}} | ||
+ | |||
+ | We recommend using GIMP or KolourPaint. | ||
+ | |||
+ | |||
+ | If you're using "GIMP", keep the options as following. | ||
+ | <code> | ||
+ | - Export as Windows BMP | ||
+ | - Compatibility Options : Do not write Color Space Information | ||
+ | - Advanced Options : 24 bits | ||
+ | - Name : "boot-logo.bmp" | ||
+ | </code> | ||
+ | |||
+ | If you're using KolourPaint, refer to the following. | ||
+ | <code> | ||
+ | - Save Image as | ||
+ | - Filter : Windows BMP image | ||
+ | - Convert to : 24-bit Color | ||
+ | </code> | ||
+ | |||
+ | And please keep the size of your bmp file must be under 2MB because the logo partition is limited to 2MB. | ||
+ | Gzip BMP format is supported, so if the size is over 2MB, you can use bmp.gz file. | ||
+ | <code> | ||
+ | $ gzip boot-logo.bmp | ||
+ | $ ls | ||
+ | boot-logo.bmp.gz | ||

+ | If you will use bmp data on logo partition, make sure there is NO boot-logo.bmp.gz file on your VFAT area, because U-Boot checks very first if there is boot-logo.bmp.gz on VFAT area and then check logo partition. | ||
