Hi,

yesterday i got my orange pi board and 2 original orange pi camera modules. Unfortunatelly i was not able to activate the camera with the bananian image form the orange pi download section.

I tried this:

modprobe ov5640
modprobe sun4i_csi0
dmesg

[CSI]V4L2 device registered as video0
[CSI][OV5640]disalbe oe!
[CSI_ERR][OV5640]chip found is not an target chip.
[CSI_ERR]sensor initial error when csi open!

Has anyone activate the camera?

Thanks
atomiq

This are the parameters in the FEX-File:

I'm trying to get it working as well under Lubuntu but until now, no success at all. I continue to investigate and will keep you informed.

Hi,
Take a look here, you certainly have to configure this.

Thanks for the link, gaara. You are right, i have to configure the FEX.

Does anyone know, which chip is used by this camera and what are the right parameters:

http://www.aliexpress.com/store/ ... 71_32255931892.html

The cable is labelled with: SH-2035-IPLAY but i did not find any information.

If this is the "official" camera it should be supported by the "official" images

This are the parameters in the FEX-File:

  35. [camera_list_para]

  55. ov5650_mv9335 = 0
  56. siv121d = 0
  57. gc2035 = 0

I checked the user manual and the schematics. The ports seem to be right.

i2cdetect -y 1 gives me the device address 0x3c and i can read the registers with i2cdump -y 1 0x3c.

The communication between the board and the camera seem to work.

But if i used modprobe sun4i_csi0 i2c_addr=0x3c ccm="ov5640" i get:

[ 1844.630141] incomplete xfer (0x20)
[ 1844.634424] [CSI_ERR][OV5640]Error -70 on register write
[ 1844.646490] [CSI_ERR][OV5640]sensor_read err at sensor_detect!
[ 1844.658511] [CSI_ERR][OV5640]chip found is not an target chip.
[ 1844.670003] [CSI_ERR]sensor initial error when csi open!

Is there any way to get information about the chip on the camera module?
