Autologin does not work in petalinux 2016.4

Hi all,

i know that there are several questions like mine but it does not work yet on my Zybo board target. Though i tried a lot of threads in this forum but something is going wrong.

I am working with Petalinux 2016.4 and Zybo board 7010. I want simply to make an Autologin for my image as described in the manual ug1144(2016.4) and i tried this https://forums.xilinx.com/t5/Embedded-Linux/Petalinux-2016-4-autologin/td-p/817119 thread step by step.


My configurations are:

1- In /<project_dir>/bild/conf/local.conf i added the line

EXTRA_IMAGE_FEATURES = "debug-tweaks"

2- In /<project_dir>/project-spec/meta-plnx-generated/recipes-core/images/petalinux-usr-image.bb i deleted the lines:

“inherit extrausers”

“usermod -P root root;”

3- I created a new app called autologin in recipes-apps

$ petalinux-create -t apps --template c --name myapp --enable

4- The file /<project_dir>/project-spec/meta-user/recipes-apps/autologin/autologin.bb has the content:

# This file is the autologin recipe.
SUMMARY = "Simple autologin application"

LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "file://autologin.c \
		file://Makefile \
		file://autologin.sh \
INITSCRIPT_NAME = "autologin"

S = "${WORKDIR}"

inherit update-rc.d

do_compile() {

do_install() {
		install -d ${D}${bindir}
		install -m 0755 autologin ${D}${bindir}
		install -d ${D}${sysconfdir}/init.d/
		install -m 0755 autologin.sh ${D}${sysconfdir}/init.d/autologin

5- Finally, /<project_dir>/project-spec/meta-user/recipes-apps/autologin/autologin/autologin.sh has the content:

exec /bin/login -f root

but i am getting in console always the following output:

 I also tried to change /etc/inittab file in rootfs by doing a patch but the patch was ignored. It would be nice to give suggestions how to deal with this problem.
