linux - Yocto Custom Image Recipe 不会将文件安装到最终的 rootfs 中

Question

我已经编写了一个自定义的 Yocto Bitbake 食谱，并粘贴在下方。我执行了如下所示的某个 ROOTFS_POSTPROCESS_COMMAND 作为包含此配方的完整镜像构建的一部分。目前，镜像是在镜像 do_rootfs 步骤中，因为 rootfs 目录中缺少 TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts 文件。

cleanup_ble_baud_rate_function() {
    mv ${IMAGE_ROOTFS}/lib/firmware/ti-connectivity/TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts ${IMAGE_ROOTFS}/lib/firmware/ti-connectivity/TIInit_11.8.32.bts
}

ROOTFS_POSTPROCESS_COMMAND_append_am57xx-phycore-rdk_arago = " cleanup_ble_baud_rate_function;"

这是食谱:

LIC_FILES_CHKSUM = "file://${CUSTOM_LAYER_DIR}/licenses/${LICENSE};md5=d41d8cd98f00b204e9800998ecf8427e"

# We depend on python and dbus

FILES_${PN} += "/lib/firmware/ti-connectivity/TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts"

do_install() {
  install -d ${D}${bindir}
  install -m 755 ble-service.py ${D}${bindir}
  install -m 755 setup-bluetooth-radio.sh ${D}${bindir}

  install -d ${D}/lib/firmware/ti-connectivity
  install -m 755 TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts ${D}/lib/firmware/ti-connectivity/

  install -d ${D}${sysconfdir}/systemd/system
  install -d ${D}${sysconfdir}/systemd/system/multi-user.target.wants
  install -m 0644 ${S}/bluetooth.service ${D}${sysconfdir}/systemd/system
  ln -s ../bluetooth.service ${D}${sysconfdir}/systemd/system/multi-user.target.wants/bluetooth.service

  # Actually use socket based activation for this service
  install -d ${D}${sysconfdir}/systemd/system/sysinit.target.wants
  ln -s ../bluetooth.service ${D}${sysconfdir}/systemd/system/sysinit.target.wants/bluetooth.service
}

镜像构建失败后，当我执行 Linux updatedb 和 locate 命令时，显示以下结果:

我同意 Oleksandr 在这一点上的观点。不要使用 postprocess 命令，它可能不会按照您的想法进行。相反，只需确保您使用 ${S} 并且您的 FILES_${PN} 会简单得多。

install -m 755 ${S}/TIInit_11.8.32-115200_no_dsm-TI_P2.136.bts ${D}/lib/firmware/ti-connectivity/

FILES_${PN} += "${libdir}/firmware/ti-connectivity/*"

在 tmp/work/target/recipename 中调试你的 recipe install 将帮助你弄清楚事情的进展。
