NanoPi NEO AIR & CAM500B problem

Tanat · June 13, 2017

Hi all.

I install Ubuntu_xenial_default with kernel 3.4.113 and want record video from CAM500B with ov5640 image sensor.

I had edited camera section in fex file with next options:

And had added to file /etc/modules

ov5640

vfe_v4l2

After reboot I can list video0 device in /dev

but dmesg | grep ov5640 and dmesg | grep VFE returns nothing.

And dmesg | grep OV5640 show

[    7.860317] [OV5640@lex]init_sensor - frame_rate: 0, max_win_size: 11
[    7.952205] [OV5640@lex]CSI_SUBDEV_PWR_ON!
[    8.020823] [OV5640@lex]sensor_init 0x0
[    8.065071] [OV5640@lex]CSI_SUBDEV_PWR_OFF!

Then ffmpeg -f v4l2 -s 640x480 -i /dev/video0 -r 30 -c:v mpeg4 ./test/test.avi returns error:

ioctl(VIDIOCENUMINPUT): invalid argument

/dev/video0: Invalid argument.

Please help me with this problem.

I had tried to boot without camera and dmesg | grep OV5640 displayed:

init_sensor - frame_rate: 0, max_win_size: 11
CSI_SUBDEV_PWR_ON!
sensor read rety=2
error at sensor_detect
chip found is not an target chip
CSI_SUBDEV_PWR_OFF!

And tried to boot with had connected camera then dmasg | grep OV5640 displayed next:

init_sensor - frame_rate: 0, max_win_size: 11
CSI_SUBDEV_PWR_ON!
sensor_init 0x0
CSI_SUBDEV_PWR_OFF!

Then agian I may list /dev/video0 but no access to this device

I tried to recompile ov5640 and vfe modules with DEV_DBG_EN 1

and now after commands modprobe ov5640 vfe_v4l2 I can see next:
