Using Orange-pi camera with libretech-all-h3-cc-h2-plus

Rhythm

Has anyone tried using orangep-pi cameras with DVP camera interface of libretech-all-h3-cc-h2-plus board.
Or which camera would be compatible for the boad's camera interface.
Thanks.

Rhythm

Does the pin-out of both match?

loverpi

Camera modules are in development. Orange Pi has multiple cameras that follow different standards so we can't tell you which one will work and which one won't.

Rhythm

So, which camera module would you suggest to be used with this board?
Actually, I had a look at camera schematics, the pinout of data-pins look in random order. I am not sure if its usual or specific to this board.
I just want to use DVP interface to connect to a camera module.

Rhythm

Also I just noted in schematics, in Camera section under the CON2 pinout, Its mentioned

GC2035 200W
FPC24PIN_0_5MM_TOP

Does this mean GC2035 camera module should work properly?
Thanks

Rhythm

Any suggestions about this?

I have got Omnivision OV5640 camera sensor and I tried to build corresponding OV5640 module in kernel, but after loading module in system using modprobe I couldn't see any /dev/video0 nor is there any error.
How can I bring up the board to support CSI camera interface
Please suggest

loverpi

Bootlin hasn't finished the upstream driver for OV5640. There was some conflict between the CSI and DVP versions that wasn't resolved. You need to patch the kernel. I'll see if I can find the exact text.

loverpi

There is already some support for the OV5640 camera sensor connected
via a parallel interface. However, this support is a bit limited,
and Maxime has already submitted a patch series adding support for
more resolutions and framerates, and generally improving the driver
by removing lots of hardcoded initialization. This patch series
hasn't been merged yet, as there are some discussions with other
developers that use the OV5640 on MIPI CSI, and which are seeing
issues. Unfortunately, since we don't have a platform with an OV5640
on MIPI CSI, we can't help much in the debugging, and the topic is a
bit blocked.

So it really depends on what you want: minimal support for OV5640
(in which case it already exists and there's no effort needed) or
improved support for OV5640, in which case we would need more
details about which specific features you're interested in.

Rhythm

Thanks for the information. As of now, since my board can't even detect the camera on DVP port. Firstly, I want it to recognise. Please suggest some reference(if any), that could help me getting started. After that, I am planning to stream video from camera, where I can view it from my laptop etc.
Thanks.

Please suggest some guide where I can start or find the appropriate kernel patch you are talking about.

P.S.: I tried googling, but results are inclined towards raspberry pi. Please help

loverpi

Do you have the exact link to where you purchased it? There's two or three models for Orange Pi cameras.

The pinout seems to match. Have you checked Android?

Rhythm

Sorry, I didn't get you.
Which Android are you referring to?

Rhythm

Do you mean installing Android Image?
If so, the readme of Android image says that H2+ is not supported, due to limited RAM.

loverpi

Try it.

Rhythm

Okay, I'll try it.
But the `Phoenix USB pro` used to flash image is available for windows and I'm currently using ubuntu. So setting up windows and testing would take couple of days.
Meanwhile, if you can share your kernel `.config` file which has `OV5640 camera sensor` support enabled, that would be helpful.
Thanks.

loverpi

We don't have one.

Rhythm

Okay. I'll test with Android then.

Rhythm

The android image doesn't seem to have any partition table. So flashing it directly into sdcard won't help, right?

Rhythm

Hi, I was trying to install android image and instead of emmc, I have sdcard. But Image can't be flashed.
Following is the log error on uart.

The only difference from readme is instead of emmc , I'm using sdcard.
Please suggest.

Rhythm

These are the logs before above image

Rhythm

Does it help anyways?

loverpi

The Android release so far only supports eMMC.You may have to wait until Android is released for MicroSD card. That is low on the priority list right now. You can also try on linux-sunxi IRC.

Rhythm

Where can I find the image for this particular board?

Rhythm

Or if you can get me the kernel config you are using for the same, it would be a great help.

Rhythm

And also, I think I might be missing the DVP camera interface driver, Can you tell if it's already in kernel menuconfig or is it some external patch?

Rhythm

Can you please suggest me the driver you are using for parallel port communication?
Thanks

Rhythm

Hi,
Do you have the device tree config for the camera available with you? I have applied a patch for the same but there seems to be an issue with device-tree config only. Also according to schematics the data pins for camera interface also appears shuffled.
If you share the device tree config for ov5640 camera sensor, it'll be very helpful.
Thanks

Rhythm

Hey,
Has anybody ever seen OV5640 camera sensor working with this board?
I got all device tree and patches sorted, but now, I2C bus is being locked when trying to probe for ov5640 sensor. Time out is occuring on the I2C bus for that particular bus only, where sensor is connected.
Following is the dmesg log for that section:

[    9.118124] i2c i2c-2: mv64xxx: I2C bus locked, block: 1, time_left: 0
[    9.127204] ov5640 2-003c: ov5640_read_reg: error: reg=300a
[    9.137871] ov5640 2-003c: ov5640_check_chip_id: failed to read chip identifier
[    9.145426] ov5640: probe of 2-003c failed with error -110

I have checked in the kernel code, error code 110 refers to Connection Timed Out.

Please help me figure it out.
