ok i was able to preceed a little. The new error message after booting is:

current settings are:

flash_header.c
struct imx_flash_header_v2 __flash_header_section flash_header =
{
    .header.tag         = IVT_HEADER_TAG,
    .header.length      = cpu_to_be16(32),
    .header.version     = IVT_VERSION,

    .entry              = APP_DEST + 0x1000,
    .dcd_ptr            = APP_DEST + 0x400 + offsetof(struct 
imx_flash_header_v2, dcd),
    .boot_data_ptr      = APP_DEST + 0x400 + offsetof(struct

    .self               = APP_DEST + 0x400,

    .boot_data.start    = APP_DEST,
    .boot_data.size     = 0x80000,

    .dcd.header.tag     = DCD_HEADER_TAG,
    .dcd.header.length  = cpu_to_be16(sizeof(struct imx_dcd) + sizeof
(dcd_entry)),
    .dcd.header.version = DCD_VERSION,

    .dcd.command.tag    = DCD_COMMAND_WRITE_TAG,
    .dcd.command.length = cpu_to_be16(sizeof(struct imx_dcd_command) + 
sizeof(dcd_entry)),
    .dcd.command.param  = DCD_COMMAND_WRITE_PARAM,
};


Environment config
nand_parts="512k(barebox)ro,512k(bareboxenv),4M(kernel),120M(root)"


board_init.c
devfs_add_partition("nand0", 0x00000, 0x80000, PARTITION_FIXED, "self0");
devfs_add_partition("nand0", 0x80000, 0x80000, PARTITION_FIXED, "env0");


seems like the enviroment.c->envfs_load() looks into a wrong memory area.
Is there a Setting i forgot?

Her you write 512k for env

And here you say its 786k.
