Hello.
I would like to use the kintaro super ursus power switch with my batocera PI3+ box.
i am trying to edit etc/init d sequences with Kintaro scripts but does not work for me.
I am using those scripts :
#! /bin/sh
case "$1" in
start)
echo "Starting SNES"
run application you want to start
python /opt/Kintaro/kintaro.py &
;;
stop)
echo "Stopping SNES"
kill application you want to stop
killall python
;;
*)
echo "Usage: /etc/init.d/example{start|stop}"
exit 1
;;
esac
exit 0
#!/usr/bin/python -u

GPIO.cleanup()
exit()
snes = SNES()
snes.attach_interrupts()
while True:
time.sleep(5)
snes.led(1)
snes.check_fan()
Then i am using this following sequence :
1.Connect with SSH (through Winscp in my case)
2.Remount partition on read-write with the command:
mount -o remount,rw /
3.Then copy the S100kintaro.sh into /etc/init.d
4.Copy the kintaro folder into /opt/
5.reboot
6.launch command:
chmod +x /etc/init.d/S100kintaro.sh
7.launch scripts:
/etc/init.d/S100kintaro.sh start
With that sequence, the FAN and led light of the kintaro case starts.
But when i am rebooting, the scripts are erased and are not usable anymore.
Could you please give me advices to make the kintaro works and saved on batocera system please?
Thanking you
