PetaLinux 2018.3 AutoRun application

1. create a new app projects - startup, the best all lowercase letters, otherwise there will be compiled with warnning

cd <plnx-proj-proot>/

App project to establish a shell script file:

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

Build applications engineering c language:

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

2. Edit the file project-spec / meta-user / recipes-apps / startup / startup.bb

Relevant content shell script works as follows:

#
# 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}/*"

Relevant content c language works as follows:

#
# This file is the startup recipe.
#

SUMMARY = "Simple startup application"
SECTION = "PETALINUX/apps"

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. Edit the application, project-spec / meta-user / recipes-apps / startup / files / folder in the startup file or startup.c

#!/bin/sh

echo "Auto starting, Hello PetaLinux World"

#include <stdio.h>

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

    return 0;
}

4. rootfs file system settings

petalinux-config -c rootfs

Select startup items in apps

5. compile

petalinux-build

6. The operation starts at PetaLinux ZYNQ test board, automatic operation Startup
