    To Fix it modify uboot configuration. Below is an example:

    CONFIG_ENV_OFFSET=0x884400
    CONFIG_ENV_SIZE=0x4000
    CONFIG_ENV_OFFSET_REDUND=0x8C4200
    CONFIG_ENV_SIZE_REDUND=0x4000
    CONFIG_SYS_MMC_ENV_DEV=0
     
    For the Environment offset, please prefer to Flash layout to find the corect value.
