Error the same on debian and Ubuntu.

Is not working correctly my board orange pi one?
Or is this problem armbian 3.4.113 image?
 
Thank you

The correct order to unload the driver,
I will try later.
 

in /boot/script.bin -> script.fex

 

 

[twi2]
twi_used = 0

already set, but camera not working.

Driver order unloading on the error does not affect. Segmentation fault (

Hello. I have the same problem. I'm using Orange Pi PC Plus with this camera module https://www.aliexpress.com/item/Orange-Pi-Open-source-IP-Camera-with-wide-angle-lens-Smart-Home-Control-Device-for-PC/32652476606.html

After

root@orangepipcplus:~# modprobe gc2035 hres=0 mclk=34
root@orangepipcplus:~# modprobe vfe_v4l2

I got next in dmesg

Also I checked camera in Android (which is used by default in PC Plus) and it works normally.

I tried older release of Armbian 5.20 with kernel 3.4.112 and it seems camera module works correctly

Thank you, i reproduced this version, but noted that that when accessing the camera, generates a large amount of debugging information in /var/log/syslog, /var/log/messages, /var/log/kern.log:

How to stop this notice, or this is virtually impossible to use?

Hi,

 

Got exactly the same problem with an orange pi lite, 5.25 server. I had to downgrade to 5.20 kernel (3.4.112) in order to use my gc2035.

 

Regards

I have the same problem, I haven't downgraded yet, as I am needing later kernel.

 

I've looked at the camera/vfe source code and the drivers have constant, hardcoded addresses.

 

I am wondering if anyone knows how the fex system affects these values? I have worked at ARM (symbian driver compatibility) and some issue fixes use post-build injection, but I do not know if that is how fex works?

 

Thanks :-)

Well, it was a long way and many hours lost until I finally discovered this post. I had this very same weird issue with the latest Armbian. Now I'm switching back to 5.20 test the CSI camera.

Same with Orange Pi PC lite. Have not tried to fix it.

Hasn't found a way of the solution of this problem yet
