Question

我想添加自定义yocto systemd服务。

我指的是[Enable systemd services using yocto

但无法使用bb代码。未安装在文件系统中。
（eth0.service代码可以）

如何解决？

eth0_0.1.bb

SUMMARY = "Install and start a systemd service"
SECTION = "eth0"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI += "file://eth0.service"

S = "${WORKDIR}"

inherit systemd

SYSTEMD_SERVICE_${PN} = "eth0.service"

do_install() {
    install -d ${D}${systemd_system_unitdir}
    install -m 0644 ${WORKDIR}/eth0.service ${D}${systemd_system_unitdir}/
}

FILES_${PN} += "/lib/systemd/system"

REQUIRED_DISTRO_FEATURES= "systemd"

eth0.service

[Unit]

Answer 1

如果您似乎拥有inherit systemd和SYSTEMD_SERVICE_${PN} = "eth0.service"，则应该这样做。因此，我认为您需要添加的是SYSTEMD_AUTO_ENABLE = "enable" 并确保.service文件具有您似乎也拥有的[Install]部分。其次，还要确保通过IMAGE_INSTALL_append = " eth0"

对于网络，您还可以创建一个systemd _％。bbappend

import xml.etree.ElementTree as ET

tree = ET.parse('input.xml')
root = tree.getroot()

tree2 = ET.parse('output.xml')
root2 = tree2.getroot()

for s3birch in root.findall("./Scene/TransformGroup/TransformGroup[@name='birch_stage2']"):
    translation = s3birch.get('translation')
    rotation = s3birch.get('rotation')
    scale = s3birch.get('scale')
    nodeid = s3birch.get('nodeId')
    print('Translation = ', translation)
    print('rotation = ', rotation)
    print('Scale = ', scale)
    print('NodeId = ', nodeid)
    for shape in root.findall("./Scene/TransformGroup/TransformGroup[@name='birch_stage2']/Shape[@shapeId='1']"):
        shape_nodeid1 = shape.get('nodeId')
        print('Shape 1 nodeId = ', shape_nodeid1)
    for shape2 in root.findall("./Scene/TransformGroup/TransformGroup[@name='birch_stage2']/Shape/Shape[@shapeId='2']"):
        shape_nodeid2 = shape2.get('nodeId')
        print('Shape 2 nodeId = ', shape_nodeid2)
    for shape3 in root.findall("./Scene/TransformGroup/TransformGroup[@name='birch_stage2']/Shape[@shapeId='3']"):
        shape_nodeid3 = shape3.get('nodeId')
        print('Shape 3 nodeId = ', shape_nodeid3)

for new_s3birch in root2.findall("./Scene/TransformGroup/TransformGroup[@name='birch_stage2']"):
    old_translation = new_s3birch.get('translation')
    print(*Old translation = ', old_translation)
    new_s3birch.set('translation', translation)

与output.xml：

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

SRC_URI += "file://eth0.network"

FILES_${PN} += "{sysconfdir}/systemd/network/* "

do_install_append() {
    install -d ${D}${systemd_unitdir}/network/
    install -m 0644 ${WORKDIR}/*.network ${D}${systemd_unitdir}/network/
}
