Camera problem: /dev/video0 not present

DigY · February 23, 2017

Hi,

I am trying to install and run the dedicated camera on OP Lite with Legacy 3.4.113 as written here:

http://www.cnx-software.com/2015/09/26/how-to-use-orange-pi-camera-in-linux-with-motion/

Unfortunately /dev/video0 is not present (checked by "ls /dev/video*").

Any one got the same issue?

What could be the problem?

Could you give some more information, run:

lsusb

dmesg | grep usb

sudo apt-get install v4l-utils, after that run v4l2-ctl --all

sudo apt-get install v4l-utils, after that run v4l2-ctl --all

... /dev/video0 is not present ...

v4l2-ctl won't help as there is no video4linux device

IMHO: A problem in the vfe_v4l2 module.

I created a topic with a similar problem (OS Armbian5.25), the solution isn't found yet

I have downgraded (via cmd apt-get install linux-image-sun8i=5.20)to 3.4.112 as suggested by some ppl suggested

root@orangepilite:~# uname -a
Linux orangepilite 3.4.112-sun8i #14 SMP PREEMPT Wed Sep 14 20:29:31 CEST 2016

Now /dev/video0 is present however, altough camera is connected I' getting sensor error:

root@orangepilite:~# dmesg | grep GC2035
[ 44.418232] [CSI_ERR][GC2035]sensor_read err at sensor_detect!
[ 44.418241] [CSI_ERR][GC2035]chip found is not an target chip.

Maybe it's not a fix. but solved my problem:

1. download https://dl.armbian.com/orangepilite/archive/Armbian_5.20_Orangepilite_Debian_jessie_3.4.112.7z

2. add WiFI connection: wpa_passphrase "ssid" "wirelesskey" >/etc/wpa_supplicant.conf

3. make autconnect on start-up:

- nano /etc/rc.local

- add line before "exit 0": sudo wpa_supplicant -B -D nl80211 -i wlan0 -c wpa_supplicant.conf
- add line before "exit 0": sudo dhclient wlan0

4. reboot

5. after login run: apt-get update

6. reboot

7. after login install drivers:

- sudo modprobe gc2035

- sudo modprobe vfe_v4l2

8. instal your camera program, ie: sudo apt-get install fswebcam

9. grab the pic, ie: fswebcam -r 1280x720 --no-banner image.jpg

Enjoy!

The camera ceased to work from the Armbian 5.25 version. Now I will try the 5.26 version collected from source codes

In version 5.26 same problem. The camera doesn't work.
