Custom Script not running at startup despite following guidance...
Hi. I'm trying to get a fan controller script running at startup. I've followed various approaches such as:
None of which seem to work.
The test script:
#!/usr/bin/env python import os import time import RPi.GPIO as GPIO print "Hello World Again" GPIO.setwarnings(False) GPIO.setmode(GPIO.BCM) GATE = 4 GPIO.setup(4, GPIO.OUT) InitFlash = 0 while InitFlash < 12 : GPIO.output(GATE, True) time.sleep(5) GPIO.output(GATE, False) time.sleep(3) InitFlash += 1 print "bye!"
For example, if I place this in : "share/system/custom.sh" and run manually via putty, the script works fine (toggling the gpio4 on and off). However, the script doesn't execute automatically at startup. I also tried placing it in the locations in the links above, but still no joy.
Any ideas what's going wrong?
@stigzler I should finally write a Wiki article about this topic
Anyway..here some ideas:
@stigzler have you chmodded it to u+x at least ?
Looks awesome. I'll report back once had a go with it..
move that code to a
myuberscript.py, not inside
custom.sh. And your
custom.shshould be :
#!/bin/bash python /path/to/myuberscript.py
@Substring - Thanks. I see the logic behind that now..
However, tried it - still doesn't work.
I checked S99custom in cd /etc/init.d and it matches the scripting here:
So I don't think it's that
I also chmod u+x both.
Would prefer this method over delving deeper into the image, as, if it works, it could be very straightforward. Any idea why the scripts aren't booting at startup despite that being their intended purpose?
@lackyluuk - Your guide was great. Just google translated it + very straightforward. Thanks!
However, same issue!
Scripts work when run individually, but doesn't run automatically at startup.
I'm really not sure what's going on. Any ideas? Might have to try a re-install at this rate.
@stigzler Does your script in
/etc/init.dexecute really without errors? Try to start this one. If you can start this without error, then it should work.
I executed this directly and it, in turn, called by full script. So I know both scripts work on their own.
There just seems to be a problem of startup scripts not being booted.
The only things I wonder about are:
I choose an external usb drive in recalbox (I have a USB3 drive connected to the Pi3). Dunno if that effects which scripts get called form where at startup?
My Pi seems to boot twice. I turn it on and it boots to the rainbow screen and a recalbox splash ("For recovery mode hold Shift"). It then powers down and re-boots to the normal boot screen and boots fine.
@stigzler Booting from the USB Stick should'nt be a problem. I also use one and it starts all scripts properly from init.d
About the double booting issue I really have no idea.
If possible, you could try a clean install of recalbox. (Unfortunately the servers are down at the moment, so you cannot get the clean image I guess)
@stigzler is your usb drive formatted as fat32 ?
One more suggestion : run
bash -x /etc/ini.d/S99customand paste here the output if you can't read it. I'm pretty sure it won't work because of fat32
# bash -x /etc/init.d/S99custom + test -e /recalbox/share/system/custom.sh + /recalbox/share/system/custom.sh /etc/init.d/S99custom: /recalbox/share/system/custom.sh: /usr/bin/bash: bad interpreter: No such file or directory
Does my USB3 drive need to be a different format? If so - what and how?
thanks for both of your ongoing help
Whoops! Spotted the silly error. Replaced
"bash -x /etc/ini.d/S99custom" now run the script fine manually. However, still doesn't start at startup!!
I't doing my head in this issue!
- Formatted USB3 drive to FAT32 @ 4096 Cluster size (irrelevant as tested on SD card boot only)
- Formatted the 32Gb Samsung SD card with SDCard Formatter
- Installed fresh installation of recalbox + updated to 4.0.2 (higher updates still unavailable)
- wrote a new custom.sh script in nano + placed in share\system
- placed the script fanControl.py in the same directory. CHMod'd them both
- Tested custom.sh via putty - works fine, displays "Launching Fan Control"
- Tested fanControl.py individually via putty. Work as it should.
- Restarted Recalbox. Neither script booted
Hmmm. This is soo frustrating! I thouhgt I'd hit gold with recalbox, as had tried other images to date, but this one stood head and shoulder above the rest. Until I hit this issue that is! And I need an image that can accommodate custom scripts.
Below, my two scripts:
#!/bin/bash echo "Launching FanControl" python fanControl.py
(I had to include this as a link as the pasted code caused this forum system to mark my post as Spam! Hopefully pastebin should be OK for you guys trusting links)
That's as much 'out of the box' as I can make.. Any ideas?
@stigzler I really don't know what's wrong.
But if you like you can try exactly what I did in the Wiki Article to have both scripts as .py scripts and use what I wrote in the S32StartFanControl as a subprocess
Just for trying
#!/bin/bash recallog "Launching FanControl" /usr/bin/python fanControl.py
This way you'll find "Launching FanControl" in
~/logs/recalbox.log. If you do get the output, then it's a problem with python. Notice I added the full path to python, as I don't know how the $PATH looks like at that moment.
