OV5647 not activated on Zero 2 W #4887

Open christianrauch opened 2 years ago

christianrauch commented 2 years ago

Describe the bug

I am unable to use the OV5647 with libcamera on a Zero 2 W with and up-to-date bullseye.

Steps to reproduce the behaviour

  1. install 2022-01-28-raspios-bullseye-armhf-lite
  2. run libcamera-still -o img.jpg

The program will get stuck and never return an image.

Device (s)

Raspberry Pi Zero 2 W

Additional context

This issue does not appear on a Raspberry Pi 2 and Zero (1) W. I've noticed that on those devices the camera LED turns red immediately after booting and I can consecutively use all the libcamera apps. The LED does not turn on on the Zero 2 W.

pelwell commented 2 years ago

@naushir We have tested cameras on Zero 2 W, haven't we?

naushir commented 2 years ago

@davidplowman i beloved your test plan covers this?

6by9 commented 2 years ago

Pi02 does not have a GPIO controlling the LED, so it won't ever come on (nor does Pi4).

[   20.954883] vc4-drm soc:gpu: [drm] Cannot find any crtc or sizes

Implies you're running headless (intentionally or not), but you haven't told libcamera-hello not to try displaying the preview. (-n option).

There was an early issue with Pi02 with a DT mismatch in the firmware not defining the camera shutdown line correctly due to the change to using cam1_reg, but that was fixed a fair while back.

[   10.948369] ov5647 10-0036: Consider updating driver ov5647 to match on endpoints

implies that the module is getting at least loaded. Does /dev/video0 exist?

christianrauch commented 2 years ago

but you haven't told libcamera-hello not to try displaying the preview

I am running via an ssh session without X forwarding. Using -n will have the same effect. If I enable X forwarding (ssh -X) then it will show a windows with black content, but it will get stuck too.

Does /dev/video0 exist?

Yes, the device list looks the same as on the Zero (1):

Have you tried more than one Zero 2 W (asking, not expecting)?

christianrauch commented 2 years ago

Have you tried more than one Zero 2 W (asking, not expecting)?

No. I only got the Zero 2 W recently, so I expect that it has no hardware faults.

The Zero 2 W and the OV5647 are the stock hardware pieces that I use with the latest stock raspi os. I was hoping someone can reproduce this with this hardware. If this fault occurs for all Zero 2 W + OV5647, it should be straight forward to test this.

6by9 commented 2 years ago

Tested on a standard Pi OS install. Works fine. Added the -v option to get more debug

Memory says that lite installs a slightly different set of binaries due to X being absent, but it shouldn't make any functional difference in this case.

Tested on a standard Pi OS install. Works fine.

Is this via ssh without a display and without X forwarding?

For me, this is:

Tested with no display connected, and again it produces 142 preview frames and captures a JPEG.

christianrauch commented 2 years ago

So... I actually have a second OV5647 that I just tried... and it worked.

Looking at the boards, they are not identical. Both say "P5V04A SUNNY" and "Rev 1.3" but the not-working one has a white "connector" and the working one has a brown connector.

Still, the "white connector OV5647" that does not work with the Zero 2 " does work with the other Raspberry Pis.

pelwell commented 2 years ago

does work with the other Raspberry Pis.

Is that with moving cards between the Pis, thereby ruling out configuration differences?

christianrauch commented 2 years ago

Yes, the same SD card with the armhf-lite installation and exactly the same camera. Only the cable and the Pi itself change.

pelwell commented 2 years ago

And I presume the same cable has been used with Zero W and Zero 2 W? And the Zero 2 W has been tried repeatedly, meaning that we can rule out a bad cable and poor cable seating for the failing OV5647/Zero 2 W combination?

6by9 commented 2 years ago

Raspberry Pi haven't sold the V1.3 camera board since around 2016 when the V2 IMX219 module was released. Omnivision had declared the sensor End Of Life.

There are numerous 3rd parties that have copied the design with varying degrees of accuracy. Some of the original clones required the LED line to be connected, which isn't present on the Pi02. I'm slightly surprised that the sensor responds at all over I2C if that is the case, but it's not something that is worth investigating from our side.

I always used the same cable on the same Pi. I only disconnected the camera. But this also means that the cable is ok, since one of the two OV5647 works.

christianrauch commented 2 years ago

Thanks for this information. Is this a hardware limitation or can this be fixed by an software update?

It's impossible for me to tell apart the original and a potential copy. My faulty version that does not work with the Zero 2 W looks very similar this one https://www.arducam.com/product/arducam-ov5647-standard-raspberry-pi-camera-b0033/. The "P5V04A SUNNY" is right beneath the camera sensor and the cable connector is white. My PCB additionally has the "Rev 1.3" printed on it.

My working OV5647 is different to this. It has the "P5V04A SUNNY" and "A1508" written on top of the sensor connector and a brown cable connector.

This image shows both OV5647:

pi_OV5647

How do I know which one is the original and which one is the copy?

pelwell commented 2 years ago

The one which is visibly sloppy ("P5V04A..." not printed on the connector, missing dot on the "i", Courier font, inelegant routing) looks like a copy.

6by9 commented 2 years ago

They may well both be copies. The V1 camera module was made in the early days and the silkscreen for the official modules didn't get the Raspberry Pi logo on them. Therefore there is no copyright or trademark infringement from copying the silkscreen, and it's hard to tell.

christianrauch commented 2 years ago
  1. "Some of the original clones required the LED line to be connected, which isn't present on the Pi02." -> Is this a hardware limitation or can this be fixed by an software update?
  2. Can I detect clones or faulty OV5647 somehow via querying information about the sensor via software? E.g. via serial numbers or other information, or by trying to change the state of the sensor?
6by9 commented 2 years ago

1 Hardware. There is no electrical connection on the Pi02 to pin 18 of the 22pin camera connector, which becomes pin 12 on the 15 way connector. You could short pins 17&18 together on the 22pin connector so that the one signal drove both lines.

2 No. There are no serial numbers or otherwise unique identifiers in the sensor. Anyway it's a function of the board rather than the sensor - swap the sensor itself between the two boards and I suspect that the issue will stay with the board, not the sensor module.

Support is provided for the Raspberry Pi camera modules. As this appears to be a third party module, support is going to be limited. As it works with one of your modules the Pi obviously works. Your main option would be to complain to your camera module supplier.

6by9 commented 2 years ago

Having just found what is most likely a genuine Raspberry Pi v1.3 camera module, I can confirm that it matches your second image. The trace round to the LED runs around the outside (rather than under) of the sensor itself, the font matches, and there are 12 vias at the top, all with a small copper ring around them.
