无法在 yocto 中将文件复制到我的目标设备

Question

我无法获取将一些文件复制到目标设备的方法。

目前我的 yocto 项目的图层如下所示：

layer                 path                                      priority

meta-mine            /home/juanpablo/work/yocto/meta-kwali     6

meta-mine 层是我用一个配方创建的层，用于复制图像中的文件，然后我将闪存到 jetson-nano-devkit 的 sd 卡。

配方log-generators_0.1.bb有以下内容：

DESCRIPTON = "A template recipe to copy files from host directory to target. \
               The example is written with docker-compose files"
LICENSE = "CLOSED"

SRC_URI = "file://.env \
       file://docker-compose.yml \
      "

FILES_${PN} += "/test"

inherit allarch

do_install() {
  install -d ${D}/test
  install -m 0755 ${WORKDIR}/.env ${D}/test/
  install -m 0755 ${WORKDIR}/docker-compose.yml ${D}/test/
}

我已经尝试按照 wiki 的食谱食谱以及 SO 中发布的类似问题的 2 或 3 个答案（例如还定义 ${S} = ${WORKDIR}，不使用 inherit allaarch 等）。

欢迎任何建议或帮助。

Answer 1

我在我的设置中尝试了你的确切配方，它似乎工作正常。

bitbake log-generators 在 build/tmp/deploy/ipk/all/ 目录中生成 log-generators{,-dbg,-dev}_0.1-r0_all.ipk（我碰巧使用 ipk）包。

在检查 log-generators_0.1-r0_all.ipk 时，我可以在 /test 中看到正确的文件。

如果您没有在目标映像中看到这些文件，我的最佳猜测是您需要在映像的安装列表中引用该包。最简单的方法是将其添加到您的 local.conf:

IMAGE_INSTALL_append = " log-generators "
