autostart.sh don't work with new version 11

alda · May 9, 2023 at 9:51 PM

I updated Libreelec to latest vesion 11 but my autostart.sh don't work after this update. In the old version was working. For me not clear what's wrong.

I have this autostart.sh to swith a gpio signal from the Rpi4:

Bash

#!/bin/bash
#   Exports pin to userspace
echo "17" > /sys/class/gpio/export

# Sets pin 17 as an output
echo "out" > /sys/class/gpio/gpio17/direction

# Sets pin 17 to high
echo "1" > /sys/class/gpio/gpio17/value

this files I have in the /storage/.config folder

Please can you help what's wrong ?

Thanks

Perhaps background the content in the script and insert a sleep period to see if it's timing related and a delay will fix?

Hi,

As first step, you should try these commands one by one in a SSH terminal. Maybe you will get some error message (what's not visible when run from autostart.sh)...

OK when I will send commands step by step in the SSH terminal, it's working.

Bash

#!/bin/bash
(
sleep 10
echo "17" > /sys/class/gpio/export
echo "out" > /sys/class/gpio/gpio17/direction
echo "1" > /sys/class/gpio/gpio17/value
)&

^ see if that works then? .. if it does there's a timing issue and you should switch to a system.d service and schedule the events properly in the userspace boot sequence (autostart.sh is a rather blunt tool).

so my autostart.sh looks like this:

Bash

#!/bin/bash
(
sleep 10
#   Exports pin to userspace
echo "17" > /sys/class/gpio/export
# Sets pin 17 as an output
echo "out" > /sys/class/gpio/gpio17/direction
# Sets pin 17 to high
echo "1" > /sys/class/gpio/gpio17/value
)&

But it doesn't work

I would say your autostart.sh file is DOS formatted and not UNIX one.

alda · May 10, 2023 at 6:29 PM

ok, what is correct formating ? Same autostart.sh I used in my old libreelec v10 installation without any problem. Strange. So what to change ?

**CvH** · May 10, 2023 at 8:42 PM

what happens if you start it with ./autostart.sh at the ssh commandline ?

alda · May 10, 2023 at 8:48 PM

strange

Code

LibreELEC:~/.config # ./autostart.sh
-sh: ./autostart.sh: not found

alda · May 10, 2023 at 9:37 PM

tried other instruction :

Code

LibreELEC:~/.config # sh ./autostart.sh
: Permission deniede 3: can't create /sys/class/gpio/export
: nonexistent directory can't create /sys/class/gpio/gpio17/direction
: nonexistent directory can't create /sys/class/gpio/gpio17/value
: not found.sh: line 8:
LibreELEC:~/.config #

q.e.d. vpeter is right.

Use dos2unix autostart.sh

alda · May 11, 2023 at 5:49 AM

OK, it was my problem.

Code

dos2unix autostart.sh

solved my problem

Thank you

"Permission deniede 3: can't create /sys/class/gpio/export"

Should be checked the owner and permission of that autostart.sh file.

Try with SSH: ls -l ~/.config/autostart.sh

**chewitt** · May 13, 2023 at 5:27 AM

Owner and permissions are never an issue as 'the' user in the OS is root and we deliberately execute bash and call the script to avoid the need for users include a shebang or make the script executable. And.. the problem was already resolved.

autostart.sh don't work with new version 11
