[Yocto] Run scripts on startup boot

petertseng — Wed, 13 Mar 2024 08:34:58 GMT

I'm currently using i.MX Linux Yocto BSP (mickledore-6.1.22-2.0.0)

I added initscripts_%.bbappend file:

FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:" DEPENDS = "update-rc.d-native" RDEPENDS:${PN} = "update-rc.d" SRC_URI += " \ file://backlightset.sh \ " # Without this it is not possible to patch checkroot S = "${WORKDIR}" do_install:append () { install -m 0755 ${WORKDIR}/backlightset.sh ${D}${sysconfdir}/init.d update-rc.d -r ${D} backlightset.sh start 20 S . } MASKED_SCRIPTS += " \ backlightset \ "

and added the script: backlightset.sh

#!/bin/sh # # SPDX-License-Identifier: GPL-2.0-only # ### BEGIN INIT INFO # Provides: backlightset # Required-Start: mountvirtfs # Required-Stop: # Default-Start: S # Default-Stop: # Short-Description: Setup backlight ### END INIT INFO echo 60 > /sys/class/backlight/lvds_backlight/brightness

After booting I check the following files:

/etc/init.d/backlightset.sh

/etc/rcS.d/S20backlightset.sh -> ../init.d/backlightset.sh

/etc/systemd/system/backlightset.service -> /dev/null

But the script does not seem to be executed.

$ cat /sys/class/backlight/lvds_backlight/brightness 80

How can I solve this problem?

Thank you in advance!

Best Regards
Peter
