I followed this article:

https://developer.toradex.com/csi-camera-module-5mp-ov5640-linux#Apalis_TK1

And I applied this change in device-tree.

Is there any particular reason for you to set this question on private? With private questions, there is no way for the community to provide feedback or profit from any feedback.

What exact camera and hardware revision thereof have you connected?

What exactly is it that is not working for you?

What device-tree changes are you exactly talking about? I am not aware of any such being required.

Why exactly are you running the boot loader from BSP 2.8.5 and the Linux kernel from 2.8.4?

  • Camera OV5640: V1.1A

  • When loading the module tegra_camera generates several “errors”, however, the device is created /dev/video0 and /dev/video1 but when running gst-launch-1.0:

I’ve tested it now: U-Boot 2016.11-2.8.4+g07edca0 same problem, and about Device-tree, I’ve tested with and without changed.

At least stock BSP 2.8b5 works just fine with our OV5640 see the log file.

The /dev/video0 resp. /dev/video1 do not relate to the OV5640 driver in your case as may be seen from those lines:

 [  107.590313] ov5640 2-003c: Failure to read Chip ID (high byte)
 [  107.596199] ov5640: probe of 2-003c failed with error -22

 [  107.626364] ov5640: probe of 2-003d failed with error -22

Whereas in the good case that would read as follows:

[   73.927968] vi vi.0: Supporting mbus format code 0x2006 using YVU420 (YV12) planar

So it looks that at least the I2C connection resp. power to your OV5640 module seems broken.

If you want to decrease the amount of bogus errors being reported during camera probing just remove the Linux kernel modules you are not interested in e.g.:

root@apalis-tk1:~# mv /lib/modules/3.10.40-2.8.5+gccecdb3d6b3b/kernel/drivers/media/i2c/soc_camera/a* ~/
root@apalis-tk1:~# mv /lib/modules/3.10.40-2.8.5+gccecdb3d6b3b/kernel/drivers/media/i2c/soc_camera/imx135_v4l2.ko ~/
root@apalis-tk1:~# mv /lib/modules/3.10.40-2.8.5+gccecdb3d6b3b/kernel/drivers/media/i2c/soc_camera/tc358743.ko ~/

Which should result in a much leaner and easier to debug situation:

root@apalis-tk1:~# echo 250 > /sys/class/gpio/export
root@apalis-tk1:~# echo low > /sys/class/gpio/gpio250/direction
root@apalis-tk1:~# echo 248 > /sys/class/gpio/export
root@apalis-tk1:~# echo low > /sys/class/gpio/gpio248/direction
root@apalis-tk1:~# echo high > /sys/class/gpio/gpio250/direction
root@apalis-tk1:~# modprobe videobuf2-dma-contig

I would recommend double-checking your connection both on the Ixora as well as the OV5640 camera side. Make sure it is as per datasheet (e.g. with the blue stripes of the FFC cables facing to the top when plugged in).

We make the connection as oriented in the manual as the attached image, disconnect and connect several times but without success!

I ended up publishing here, because it exhausted my alternatives.

That looks correct. I assume you did plug that FFC in all the way. Let me post a picture of my board just to make this clear.
