Comment 3 for bug 1532217

Chris, i just tested it on a clean system:

1) download and dd on a sd card this image: http://people.canonical.com/~ppisati/ubuntu_embedded/ubuntu-embedded-16.04-raspi2.img.xz
2) sudo apt-get update
3) sudo apt-get install libraspberrypi-bin libraspberrypi-dev
4) modify /boot/firmware/config.txt, and comment out these two lines:

#dtparam=i2c_arm=on
#dtparam=i2c_vc=on

and append these at the end:

gpu_mem=128
start_x=1

5) reboot
6) sudo raspistill -o foobar.jpg

It works.

If it still doesn't work for you, i think you might have a setup problem - can you try your board with the raspbian image?

Do not use raspi-config with our image: it's a tool tailored for the raspbian image (we don't mount stuff in the same place, we don't have lua or whiptail, etc) and all it does when you enable the camera through it is to just modify config.txt as mentioned above.
