PetaLinux 2018.3 自动运行应用程序

1. 建立新的 app 工程 - startup,最好都用小写字母,否则编译时会有warnning

cd /

建立shell脚本文件的app工程:

petalinux-create -t apps --template install -n startup --enable

建立c语言的应用程序工程:

petalinux-create -t apps --template c -n startup --enable

2. 编辑文件 project-spec/meta-user/recipes-apps/startup/startup.bb

shell脚本工程相关的内容如下:

#
# This file is the startup recipe.
#

SUMMARY = "Simple startup application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "file://startup \
	"

S = "${WORKDIR}"

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

inherit update-rc.d

INITSCRIPT_NAME = "startup"
INITSCRIPT_PARAMS = "start 99 S ."

do_install() {
	     install -d ${D}/${sysconfdir}/init.d
	     install -m 0755 ${S}/startup ${D}/${sysconfdir}/init.d/startup
}
FILES_${PN} += "${sysconfdir}/*"

c语言工程相关的内容如下:

#
# This file is the startup recipe.
#

SUMMARY = "Simple startup application"
SECTION = "PETALINUX/apps"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "file://startup \
	   file://Makefile \
	"

S = "${WORKDIR}"

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

inherit update-rc.d

INITSCRIPT_NAME = "startup"
INITSCRIPT_PARAMS = "start 99 S ."

do_compile() {
	     oe_runmake
}

do_install() {
	     install -d ${D}/${sysconfdir}/init.d
	     install -m 0755 ${S}/startup ${D}/${sysconfdir}/init.d/startup
}
FILES_${PN} += "${sysconfdir}/*"

3. 编辑应用程序,在 project-spec/meta-user/recipes-apps/startup/files/ 文件夹里的 startup 或 startup.c 文件

#!/bin/sh

echo "Auto starting, Hello PetaLinux World"
#include 

int main(int argc, char **argv)
{
    printf("Auto starting, Hello PetaLinux World!\n");

    return 0;
}

4. rootfs文件系统设置

petalinux-config -c rootfs

在apps项选取startup

5. 执行编译

petalinux-build

6. 运行,在ZYNQ实验板启动PetaLinux,startup 自动运行
