我正在使用 SWUpdate 使用 A+B（双拷贝）方案为我的 Avnger96 板安装更新。我正在将 SWUpdate 与 Yocto 集成。但是在使用命令行参数在本地安装更新时，安装失败并出现错误：

尝试使用 CLI 进行更新swupdate -H dh-stm32mp1-dhcor-avenger96:1.0 -e stable,copy2 -v -i /tmp/avenger96-swu-v1-dh-stm32mp1-dhcor-avenger96-20220222133501.swu -k /etc/swupdate/swupdate-public.pem

sw-description如下：

software =
{
    version = "0.1.0";

    dh-stm32mp1-dhcor-avenger96 = {
    hardware-compatibility: ["1.0"];
        stable : {
            copy1 : {
                images: ({
                        filename = "core-image-minimal-dh-stm32mp1-dhcor-avenger96.ext4.gz";
                        sha256 = "@core-image-minimal-dh-stm32mp1-dhcor-avenger96.ext4.gz";
                        type = "raw";
                        compressed = "zlib";
                        device = "/dev/mmcblk0p4";
                });
                bootenv: (
                {
                    name = "rootfspart";
                    value = "4";
                },
                );
            };
            copy2 : {
                images: ({
                        filename = "core-image-minimal-dh-stm32mp1-dhcor-avenger96.ext4.gz";
                        sha256 = "@core-image-minimal-dh-stm32mp1-dhcor-avenger96.ext4.gz";
                        type = "raw";
                        compressed = "zlib";
                        device = "/dev/mmcblk0p5";
                });
                bootenv: (
                {
                    name = "rootfspart";
                    value = "5";
                },
                );
            };
        };
    }
}

我在 menuconfig 中设置了“启用签名图像验证”。

SWUpdate menuconfig

我还有一个关于在我的设备上安装的 rootfs 的问题。目前设备是用 启动的/dev/mmcblk0p4，但我可以看到在 linux 用户空间rootfsB中也安装了（/dev/mmcblk0p5）。我正在使用.wksYocto 的文件来构建双分区方案。

.
.
part / --source rootfs --ondisk mmcblk0 --fstype=ext4 --label root_A --part-name "rootfs_A" --align 4096 --use-uuid --active
part /rootfsB --source rootfs --ondisk mmcblk0 --fstype=ext4 --label root_B --part-name "rootfs_B" --align 4096 --use-uuid

bootloader --ptable gpt

我不确定为什么会发生这种情况，这是预期的行为吗？

谁能告诉我关于 SWUpdate 的问题以及如何解决它？

您的帮助将不胜感激。

提前致谢。

PS：如果这里缺少任何信息，请告诉我。
