@Boken-Lin said in Execute a script at startup:

Please let me know if that works.

for the records I want to let everyone know that this solved the problem for me. I created startup.sh that is called from /etc/rc.local and includes a line with sleep 20 and the script I want the Onion to run at startup.

thanks for the info,

@fossette & @Luciano-S

thanks both for your input.
@fossette: I'm clear about the potential of screewing up a cron-job due to relative paths, but as pointed out (and as explained by @Luciano-S being a standard-not-installed-on-openWRT-command) the missing sudo command was the problem.

@Kit-Bishop: THANK YOU - you saved my day ;-)!!!

1. Look in /var/log/syslog to see if this gives any info about (attempts to) mail the output

no data to be found here.

1. Change your crontab commands to redirect stdout (and/or stderr) to known files. E.G. change your crontab commands to something like:
   • */2 * * * * sudo python /root/py/dht.py 1>>/root/dht.py.out 2>>/root/dht.py.err
   • */2 * * * * sudo date >> /root/ct.test 1>>/root/ct.test.out 2>>/root/ct.test.err

this was the game changer! generating the error log showed that sudo is the problem! command not found and therefore the scripts did no run :rolling_eyes: !

To be complete:

• dht.py is a simple python script that reads a DHT22 sensor and uploads the values to a webpage.
• sudo date >> /root/ct.test had no other purpose than to see if the cron-demon is actually executing (was before I was aware of the logread command).

thanks again - need to remember this!!

best regards,

Dear all,

I have an issue with crontab. I have following file
#min hour day month dayofweek command
*/2 * * * * sudo python /root/py/dht.py
*/2 * * * * sudo date >> /root/ct.test
and have restarted and enabled the service using
/etc/init.d/cron start
/etc/init.d/cron enable
but no results of the scripts to be seen :-(.

logread shows the following output
Fri Nov 4 20:12:00 2016 cron.info crond[2154]: USER root pid 2378 cmd sudo python /root/py/dht.py
Fri Nov 4 20:12:00 2016 cron.info crond[2154]: USER root pid 2379 cmd sudo date >> /root/ct.test
Fri Nov 4 20:14:00 2016 cron.info crond[2154]: USER root pid 2390 cmd sudo python /root/py/dht.py
Fri Nov 4 20:14:00 2016 cron.info crond[2154]: USER root pid 2391 cmd sudo date >> /root/ct.test
so I would expect that the cron job is actually being executed as defined.

?? But why do I not get the result of the scripts / commands being run ?? If I run them from command prompt I get what I would expect...

I am confused and have not been able to find anything on the web/in the forum on this. Might be that I not scanning for the right term, so any input would be appreciated.

thanks a lot,
GoSch

thanks for the info.

Hello,

@Luciano S: thanks for the input. I have tried this in a number of configurations, but will do so again.

@administrators: which pins do I need to shorten on the actual Onion board to get the RESET signal?

Is there a description (or video) of a working startup sequence?

thanks,
Gordon

I also have a video of the power-up sequence.

Hi,

I know that the factory reset does not work, because the unit does not go back into the status it had when I originally received it - easiest indication is that I do not see the onion AP!

Here's my (very staight forward) setup...

you can see the amber light is permantent on.

Gordon

Hi,

I have not had my Omega running for a few weeks. Powering up it does a number of blinks and then the amer light is premanent on - but I cannot "find" the unit.

• I do not see the unit in my WiFi network - as I did before
• I do not see the unit as an AP - as I did originally
• I cannot factory reset using the two or three proceducres I found here
• I cannot connect via USB/Serial (using CP210x_VCP_Windows) - putty stays black
• I only have the mini dock, but no "big" dock (I am waiting for the battery dock which has never been shipped)
• I do not have an ethernet dock

**what to do? **

thanks,
Gordon

Hi,

have you ever shipped the Battery Dock? I have received mine yet.

thanks,
Gordon
