Hi @Archangel1235

Is there any way to attach a log file here

24

use paste-bin and attach the link

25

@Archangel1235, Here is the link to the logs

khadas-ov7251-camera-logs - Pastebin.com

Please review itā€¦

26

are you sure you are able to write to the sensorā€¦?

It seems that the device ID is being read as 0 meaning the camera and ISP are not communicating properly

27

hi @Archangel1235 ,

Yes ,I am able to read the ID of the camera.
If you could locate following line in the logs :

[ 23.220457] sensor_get_id@OV7251_drv.c:329 GENERIC(ERR) :
[ 23.220459] sensor_get_id: Read sensor id : 7750

I have verified it from the datasheet.

Can you please look at itā€¦

Is your problem solved? I am also debugging OV7251 recently

31

are you using a single camera module or the stereo camera module ?

32

Not yet solved

Actually we want to interface dual ov7251 camera.But currently We are first trying to make single ov7251 module work.
After the single instance work,then will proceed with dual camera

If you guys have any luck with it please helpā€¦

Hi @ninver2020,

I just came to know through another thread that you have been able to interface the ov7251 camera sensor with khadas board.
As of now we are still stuck at the ISP issue.So if you could help and guide us to solve the issue.

Hoping to get it work soon.

Thanks

This error means that the isp has not finished receiving a frame of data, and the next frame has already come.

If the 0x100000 error is always printed, there is a high probability that there is a problem with the parameter configuration of the sensor, maybe the resolution does not match.

Another possibility is that the frame rate is too high.
