    hi together,

    I don't understand why I have to skip two 512 blocks for writting the u-boot.bin to the card. Are the IVT in the u-boot.bin?
    What informations are in the first two 512 blocks of the u-boot.bin??
    Thanks for help.


    edit: Ok I find something: https://github.com/UDOOboard/U-Boot_Uni ... h_header.S
    The IVT informations are in the u-boot.bin. The Rom-Bootload need the IVT at the adress 0x00000400 ( 512 * 2 = 1024d ==> 0x400h )
    So the first 1024 bytes of the u-boot.bin are 0x00.

    Yes, i can confirm the first 2 blocks of u-boot.bin are 0x00. Your question is just curiosity or is there a particular reason?
