如何在LS1046a上使用FIT图像？

大家好，
我在 FRWY 板和我自己的定制板上使用 FIT 图像时遇到困难；两者都有同样的问题，所以我认为是我和我在做什么而不是硬件问题。
使用 FRWY 板作为讨论主题：
我可以通过以下命令使用 LSDK 21.08 构建 FIT 图像：
flex-builder -i mkitb -r ubuntu:lite这会为我生成一个名为“itb”的文件：
lsdk2108_ubuntu_lite_LS_arm64.itb
从 uboot，我可以使用 TFTP 服务器将文件上传到 DDR4 内存，如下所示：
tftpboot 0xC0000000 lsdk2108_ubuntu_lite_LS_arm64.itb使用命令“iminfo”，我可以看到 FIT 文件已正确加载，并且包含启动 linux 所需的所有部分：
=> iminfo

ERROR: Failed to allocate 0xa4039c8 bytes below 0x90000000.
ramdisk - allocation error
bootm - boot application image from memory

Usage:
bootm [addr [arg ...]]
    - boot application image stored in memory
        passing arguments 'arg ...'; when booting a Linux kernel,
        'arg' can be the address of an initrd image
        When booting a Linux kernel which requires a flat device-tree
        a third argument is required which is the address of the
        device-tree blob. To boot that kernel without an initrd image,
        use a '-' for the second argument. If you do not pass a third
        a bd_info struct will be passed instead

For the new multi component uImage format (FIT) addresses
        must be extended to include component or configuration unit name:
        addr: - direct component image specification
        addr#   - configuration specification
        Use iminfo command to get the list of existing component
        images and configurations.

Sub-commands to do part of the bootm sequence.  The sub-commands must be
issued in the order below (it's ok to not issue all sub-commands):
        start [addr [arg ...]]
        loados  - load OS image
        ramdisk - relocate initrd, set env initrd_start/initrd_end
        fdt     - relocate flat device tree
        cmdline - OS specific command line processing/setup
        bdt     - OS specific bd_info processing
        prep    - OS specific prep before relocation or go
        go      - start OS
