为覆盆子建立Mender Yocto图像

Question

我正试图为我的Raspberry Pi构建一个Mender Yocto图像，以实现远程更新的可能性。

我遵循以下说明：https://docs.mender.io/1.0/artifacts/building-mender-yocto-image

另外，我添加了这个层：https://github.com/mendersoftware/meta-mender/tree/master/meta-mender-raspberrypi

我的local.conf看起来像：

KERNEL_IMAGETYPE = "uImage"

MENDER_PARTITION_ALIGNMENT_KB = "4096"
MENDER_BOOT_PART_SIZE_MB = "40"
IMAGE_DEPENDS_sdimg += " bcm2835-bootfiles"
# raspberrypi files aligned with mender layout requirements
IMAGE_BOOT_FILES_append = " boot.scr u-boot.bin;${SDIMG_KERNELIMAGE}"
IMAGE_INSTALL_append = " kernel-image kernel-devicetree"
MENDER_ARTIFACT_NAME = "release-1"
INHERIT += "mender-full"
MACHINE = "raspberrypi3"

DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
VIRTUAL-RUNTIME_initscripts = ""

IMAGE_FSTYPES = "ext4"

我的bblayers.conf文件看起来如下：

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
/home/c3po/poky/meta \
/home/c3p0/poky/meta-poky \
/home/c3po/poky/meta-yocto-bsp \
/home/c3po/poky/oe-meta-go \
/home/c3po/poky/meta-mender/meta-mender-core \
/home/c3po/poky/meta-mender/meta-mender-demo \
/home/c3po/poky/meta-mender/meta-mender-raspberrypi \
"

除了Drew的回答外，我还补充道：

在poky文件夹中，我克隆了层：

git clone  git://git.yoctoproject.org/meta-raspberrypi

而不是我在图层中添加了：

bitbake-layers add-layer /meta-raspberrypi

以及依赖关系

git clone git://git.openembedded.org/openembedded-core
git clone git://git.openembedded.org/meta-openembedded

add-layer ../openembedded-core
add-layer ../meta-openembedded

您的配置中似乎没有平台层。有关更多详细信息，请参阅https://layers.openembedded.org/layerindex/branch/master/layer/meta-raspberrypi/。
