Camera Not Working? OPI_PC

dolod · Published in 2015-12-29 06:13:47

Hello,

I am trying to use camera in Ubuntu Mate / Debian 8 (laboris img). However my cam is not working.
Maybe someone could share knowledge?

P.S. I was trying to read other posts, however same result :/

My USBs, LAN, GPIO are working fine. Except camera...
I am connecting CAM to OPI PC with extension board.

Some logs:

root@OrangePI:~# ls /media/boot/
lib OPI_GPIO.txt orange_pi_pc.fex script.bin uImage

Moreover, i2cdump do not detect my CAM too :/

When trying fswebcam, I get:

root@OrangePI:~# fswebcam
--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Unable to query input 0.

Copy code

Moreover, I think that something must be made with .fex. But I do not know what.
Any ideas what is wrong?

Try this:
- Edit the script.bin and copy (replace) the Fex section below and compile and replace your new script.bin :

I tryed but same results.

These two lines was different in my decompiled script.fex

vip_dev0_twi_addr = 0x78 vip_dev0_act_slave = 0x18

Copy code

I noticed that i2cdump can take address in interval 0x03 - 0x77, but in .fex I am setting 0x78.

root@OrangePI:~# i2cdump -y 0
Error: No address specified!
Usage: i2cdump [-f] [-y] [-r first-last] I2CBUS ADDRESS [MODE [BANK [BANKREG]]]
I2CBUS is an integer or an I2C bus name
ADDRESS is an integer (0x03 - 0x77)

Copy code

Is that OK?

Maybe someone could share working script.bin with cam enabled?

Can the problem be my power supply?

At the moment I am using 5V/1.5A

I am stuck here too. I have camera board with gc2035 connected to OP-PC.
Trying to stream video from /dev/video0 with no luck. I am able to capture image with fsweb and motion .

Not able to access the camera through ffmpeg/avcon

Frustrating part is OP camaera module is not working on any of the Linux image.

If you are not in such a hurry, may be we can get HW video encoding to work with this: https://plus.google.com/u/0/phot ... 6248292914478510482

Hi Lex,
Video quality is really grate.
are you using camera board with gc2035 sensor ?
is gc2035 works out of the box wit guvcview.

Thanks,
Yogesh

I am using gc2035.
guvcview does not work out of the box, you need to bypass some checking guvcview does in V4l2.
Without HW encoding you get 2 (~3) fps for streaming and 1 or 2 fps for grabbing it in mkv format.
The idea is to design a very simple program to grab the images and stream it without encoding and let the clients do the job, or use a really good sw enconding algorithm.
Maybe the BIG guys can get the HW encoding to work on H3 and this can change in near future, or the PINE64 people can convince Allwinner to help the community and we all may be happy.
Make your bet.

Thanks @lex ... can you can share guvcview hacks for OP.

Trying to get streaming out on board gc2035. As per data sheet its capable of H.264 1080p @ 30 fps.

Anyone tried gc3035 on ONE .. not able to get it working with or without camera board. fswebcam gives black image with gp-jpeg error.

how do you run fsweb?
I run like that
