我正在使用Ubuntu18.04LTS上的Yocto Warrior和meta-tegra layer ( https://github.com/madisongh/meta-tegra )为我的NVIDIA Jetson Nano构建一个根文件系统。
我想要加密我的SD卡上的某个分区,所以我需要加密安装包,这是在开放嵌入式层可用。我已经将它添加到我的映像中,并且生成的根文件系统已经安装了它。
问题是,我需要将它添加到我的initramfs中,以便在启动时自动解密我的加密卷。
我得到的错误显示为:

我为initramfs配方将cryptsetup添加到我的bbappend文件中,如下所示(显示的是整个bbappend文件):
PACKAGE_INSTALL_append = " e2fsprogs-e2fsck e2fsprogs-mke2fs e2fsprogs-tune2fs e2fsprogs-badblocks"
PACKAGE_INSTALL_append = " i2c-tools"
PACKAGE_INSTALL_append = " openssl"
PACKAGE_INSTALL_append = " cryptsetup"
如果我注释掉cryptsetup行,initramfs任务就可以正常完成。
下面是来自meta-tegra的initramfs的未附加的原始配方文件:
DESCRIPTION = "Minimal initramfs image for Tegra platforms"
LICENSE = "MIT"
TEGRA_INITRD_INSTALL ??= ""
INITRD_FSTYPES ??= "${INITRAMFS_FSTYPES}"
PACKAGE_INSTALL = "\

IMAGE_FEATURES = ""
IMAGE_LINGUAS = ""
COPY_LIC_MANIFEST = "0"
COPY_LIC_DIRS = "0"
COMPATIBLE_MACHINE = "(tegra)"
KERNELDEPMODDEPEND = ""
IMAGE_ROOTFS_SIZE = "8192"
#IMAGE_ROOTFS_SIZE = "16384"
inherit core-image
IMAGE_FSTYPES = "${INITRD_FSTYPES}"
如何成功地将cryptsetup添加到initramfs配方中?谢谢。

我也收到过完全相同的错误消息,只是它是由不同的配方触发的(不是cryptsetup,而是一些自定义配方)。
问题是,recipes (tegra-minimal-init_1.0.bb)和base-files_3.0.14.bb都试图创建“/sys”和“/proc”目录,但权限不同(一个权限为0755,另一个权限为0555)。
解决这个问题的方法是删除tegra-minimal-init_1.0.bb中的dir创建:
[eliranl@somehost]$ git diff
diff --git a/meta-tegra/recipes-core/initrdscripts/tegra-minimal-init_1.0.bb b/meta-tegra/recipes-core/initrdscripts/tegra-minimal-init_1.0.bb

或者,你可以升级到'dunfell',因为它是固定的,通过更改tegra-minimal-init_1.0.bb来创建'/proc‘和'/sys’,拥有与基本文件中相同的权限,或者只是从the specific commit向后移植这一部分
