    Dear all,

    I'm writting an script similar to makeyaffsboot where the files to burn to the flash are downloaded from a tftpserver. The script is also stored in the tftp server in .scr format. Usually, the files of the system (u-boot, uImage,...) are loaded to the address 80000000 and then saved to the flash. Could you tell me at which address I could load the script to execute? at 0x70000000?

    Thanks and best regards,
    Joaquim Duran

    Joaquim,
    It sounds like you want to use the 'source' command:
    OMAP Logic # help source
    source - run script from memory

    Usage:
    source [addr]
    - run script starting at addr
    - A valid image header must be present
    OMAP Logic #

    Check your loadaddr environment variable. If it's 0x81000000 just shift it up to 0x82000000 and use 0x81000000 as the address for loading and executing your script. That gives you a 16MB to play with and should ensure that it doesn't get stomped. If you do that make sure that your script has been updated to use the new value.

    Good luck
    .

    The script is loaded at 80000000. Thanks.
