Stopped working after upgrade

Hi,

Thanks for writing the raspicam_node.

The RPi is able to see the camera with: raspistill -o image.jpg

This was working before I did an update && upgrade and now the following errors are showing up.

Started with: ubuntu@camera:~/catkin_ws/src/weeds/launch$ roslaunch raspicam_node camerav1_1280x720.launch

NODES / raspicam_node (raspicam_node/raspicam_node)

Any ideas?

Thanks,

Permissions were the problem.

ubiquity$ ls -la /dev/vcsm
crw------- 1 root root 244, 0 Feb 11  2016 /dev/vcsm
ubiquity$ ls -la /dev/vcsm-cma
crw-rw-rw- 1 root root 10, 62 Feb 11  2016 /dev/vcsm-cma

Changing to:

ubiquity$ sudo chmod 666 /dev/vcsm
ubiquity$ ls -la /dev/vcsm                         
crw-rw-rw- 1 root root 244, 0 Feb 11  2016 /dev/vcsm

Has fixed the problem.

The permissions were getting reset after reboot.

I added a line to the bottom of /etc/rc.local sudo chmod 666 /dev/vcsm

And now it seems to work. Not sure if this is the best approach.
