I have created a new "experimental" branch with more config options that have the "dangerous" ones disabled by default.

https://github.com/alesanmanoweb/multilapse-CHDK/tree/experimental

Tomorrow I will proceed and add a "simple ftp" option

I have added the capability to perform a simple ftp upload, along with more options directly in th config file.
It would be great if somebody could try this out :D

Hi Alesan,

I tried your new version and this is the log for a clean attempt

Code: [Select]
root@raspberrypi_Zero-01:~# tail -f multilapse.log

The camera crashed - needed battery removing momentarily to come back.
The contents of multilapse was edited as follows - trying to cater for the Raspberry Pi Zero's lack of two LEDs

Code: [Select]
#!/bin/sh
echo none >/sys/class/leds/led0/trigger
echo 0 >/sys/class/leds/led0/brightness
#echo none >/sys/class/leds/led1/trigger
#echo 0 >/sys/class/leds/led1/brightness

while [ true ]
do
        /root/chdkptp/chdkptp.sh -e'exec dofile("/root/multilapse-CHDK/multilapse.$
        sleep 10
done

I hope this is useful.  I see errors related to the USB so I've googled up some more similar issues and though the following info might help troubleshoot:  Here's the result of an lsusb command

root@raspberrypi_Zero-01:~/multilapse-CHDK# lsusb
Bus 001 Device 005: ID 04a9:32aa Canon, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I see that Device 001 is identified as a root hub - the Pi Zero's single, micro usb device is described as an OTG "on the go" adaptor

Here's a sample of the output from a dmesg command

Now I remember and issue I had with my main RaspBPi machine.. each time I plugged in the camera to the USB, it was identified and associated with gphoto2 an inbuilt program.  Once I uninstalled gphoto, the problem disappeared.

I just looked for gphoto on the Zero and it's not installed but perhaps theres another product doing a similar thing?

The dmesg output certainly looks like something called 'usbfs' is connecting to the camera before chdkptp.

I'm not sure why it would be 'usbfs' though, google results for usbfs seem to mostly refer to an old kernel interface that shouldn't be a problem even if it was present.

What distro are you using? Are both pis running the same distro?

With the camera connected, you can use fuser and grep to see what the has the camera open, like
Code: [Select]
fuser /dev/bus/usb/001/005
If a process has it open, it will output the process id after the path, like
Code: [Select]
/dev/bus/usb/001/005:  1234
You can then find the program with
Code: [Select]
ps ax |grep 1234

the numbers after /dev/bus/usb should match whatever bus / device the camera is on,  which would be 001/005 in your lsusb output.

Hi Reyalp

It looks like my old enemy... gphoto 2

Code: [Select]
root@raspberrypi_Zero-01:~/multilapse-CHDK/current# lsusb
Bus 001 Device 005: ID 04a9:32aa Canon, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@raspberrypi_Zero-01:~/multilapse-CHDK/current# fuser /dev/bus/usb/001/005
/dev/bus/usb/001/005:   999
root@raspberrypi_Zero-01:~/multilapse-CHDK/current# ps ax |grep 999
  999 ?        Sl     0:00 /usr/lib/gvfs/gvfsd-gphoto2 --spawner :1.4 /org/gtk/g                                    vfs/exec_spaw/4
 1014 pts/0    S+     0:00 grep 999

however when I try to uninstall it

root@raspberrypi_Zero-01:~/multilapse-CHDK/current# sudo apt-get purge gphoto2

Try
dpkg-query -S /usr/lib/gvfs/gvfsd-gphoto2

gvfs-backends: /usr/lib/gvfs/gvfsd-gphoto2
so gvfs-backends is the package that owns it https://packages.debian.org/jessie/gvfs-backends

I'm not sure if you'd want to uninstall the whole package, but maybe there's a way to disable the gphoto part.

My Googling turned up this rather promising thread

https://superuser.com/questions/1200173/free-an-ptp-usb-device-from-gvfs-usage

But it's based on Ubuntu so I'm not sure it's compatable with raspbian
