    Hi, Margarita,

    Thanks for reply.

    I saw these links you show me. But the contents about boot logo are "nand read xxxxx, nand xxxxx".

    There is no nand flash on our board. We use "SD Card" to boot system.

    Do i miss something ? What should i set about u-boot bootcmd something like "logo on <address_bmp_image> <final_bmp DSS read address> <VPDMA Descriptor address> <Display time in seconds> <Display fps (less than 60)>"?

    If is "nand" way, it could be " 'nand read ${logoreadaddr} 0x280000 0x300000; logo on ${logoreadaddr} 0xB0000000 0xBFDD0000 40 60; tftp 0x81000000 uImage;bootm". But what if "SD Card " ?

    Thanks !
