i am new to balena and trying to add display turn on/off to a application.
the service appers on the application and running but not working .
ther error code i am getting is
10.04.19 12:51:18 (+0200) display /usr/src/start.sh: 7: /usr/src/start.sh: Syntax error: end of file unexpected (expecting “then”)
have tried too google the problem but no distinct explanation what the trouble is.
have added the Device Environment Variables
DISPLAY_OFF 43 12 * * *
DISPLAY_ON 0 7 * * *
ENABLE_DISPLAY_TIMER 1
one error/warning appers when pushing and that is
[display] debconf: delaying package configuration, since apt-utils is not installed
what i found is that i can ignore it.
orgininal i code i am using is the balena-dash-master
and added a service " display"
with script folder with start.sh display_ on.sh and display_off.sh
start.sh
#!/bin/bash`
if [ “$ENABLE_BACKLIGHT_TIMER” -eq “1” ]
then
(crontab -l; echo “${BACKLIGHT_ON:-0 8 * * *} /usr/src/backlight_on.sh”) | crontab -
(crontab -l; echo “${BACKLIGHT_OFF:-0 23 * * *} /usr/src/backlight_off.sh”) | crontab -
ficrond -f
display_off.sh
#!/bin/bash
echo 'standby 0' | cec-client -s -d 1
–
display_on.sh
#!/bin/bash
echo 'on 0' | cec-client -s -d 1
