SOLVED VEYE-MIPI-IMX327S via V4L2

Dan_LionKing

Hello.
The VEYE-MIPI-IMX327S camera I received works via veye_raspcam (veye_raspipreview, etc.). But I need to work through the V4L2 driver. The driver was installed according to the instructions, the camera does not work (see pictures).
http://wiki.veye.cc/index.php/V4L2_mode_for_Raspberry_Pi
After calling
gst-launch-1.0 v4l2src num-buffers = 1 device = / dev / video0! 'video / x-raw, format = (string) UYVY, width = 1920, height = 1080'! jpegenc! filesink location = test_image.jpg
the program hangs.
VLC player also does not display image from VEYE-MIPI-IMX327S.

When the CS-MIPI-IMX307 camera is connected to the same RPi, everything works, including through V4L2.

Can I get a working VEYE-MIPI-IMX327S camera?

Hi，
Pls do some test for me.
After power on rpi,please run this :

i2cdetect -y 10

I want to confirm if this camera is still poweron.

It's a little strange because the CS-MIPI-IMX307 on your board is normal. Please confirm two points:

The code you are using is the latest version of github.
Make sure there are no devices in the red circle in the picture below.

The preview and snap cmd just works fine here.

export DISPLAY=:0
gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080,framerate=(fraction)30/1" ! videoconvert ! fpsdisplaysink videosink=autovideosink sync=false text-overlay=false -v

gst-launch-1.0 v4l2src num-buffers=1 device=/dev/video0 ! "video/x-raw,format=(string)UYVY, width=(int)1920, height=(int)1080" ! jpegenc ! filesink location=jpgname.jpg

Please try again.
By the way, 327S support FFC cable power mode.

It feels strange, can you try veye_raspicam mode to make sure the camera is working properly?
Http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_for_Raspberry_Pi.
Remember to uninstall v4l2 driver, before you can use veye_raspicam mode.

Dan_LionKing

@veye_xumm veye_raspicam mode work fine

@dan_lionking
I think I have an idea.
This is my kernel version.

~ $ uname -a
Linux raspberrypi 5.10.17-v7l+ #1403 SMP Mon Feb 22 11:33:35 GMT 2021 armv7l GNU/Linux

So the driver I use is in 5.10.17-v7l+ dir.
I think maybe you have an older version kernel.

The earliest small amount of VEYE-MIPI-IMX327S has a small different with VEYE-MIPI-327E， It has a valid reset pin. So the driver is required to control the state of the pin. And I also implemented it in the new version of the driver.
I soon realized that this was not compatible with the older version of the driver, so we removed the diodes that were told you in post earlier to maintain compatibility.

Here are my suggestions, any one of which can achieve the goal of solving the problem:

If it is convenient for you, you can remove the diode I pointed out to you in the previous post.
Update your kernel, to use the 5.10.17 Murray v7l+ version of the driver.
Based on the source code of the veye327 driver, recompile the driver for your current version of kernel.

Dan_LionKing

@veye_xumm
I am using the newest kernel version:
pi@raspberrypi:~ $ uname -a
Linux raspberrypi 5.10.17-v7l+ #1421 SMP Thu May 27 14:00:13 BST 2021 armv7l GNU/Linux

Should I remove the diode?

veye_xumm

@dan_lionking
It seems that I was wrong, but I suggest you try the above advice.

Dan_LionKing

@veye_xumm
The diode was removed, the same thing.

veye_raspicam mode work.

Hi,After discussing with my colleagues, I think I found the cause of the problem this time.
Please read hdver, only if hdver > = 5 can you use the v4l2 mode of raspberry pi.

http://wiki.veye.cc/index.php/VEYE-MIPI-IMX327S_version_log

Because the V4L2 model and 327s products are relatively new, we discovered and solved this bug after a short period of time.
As an apology, I can give you a new 327S at half price. You can contact customer service on AliExpress or amazon.

Dan_LionKing

@veye_xumm
pi@raspberrypi:~/raspberrypi/i2c_cmd/bin $ ./veye_mipi_i2c.sh -r -f hdver
hardware version is 0x 4

veye_xumm

@dan_lionking
I think that's the problem.

Dan_LionKing

@veye_xumm
I recently ordered more modules VEYE-MIPI-IMX327S for AliExpress.

What date was this problem fixed?

veye_xumm

@dan_lionking
http://wiki.veye.cc/index.php/VEYE-MIPI-IMX327S_version_log
I think it is 20210514.

Dan_LionKing

@veye_xumm pi@raspberrypi:~/raspberrypi/i2c_cmd/bin $ ./veye_mipi_i2c.sh -r -f hdver
hardware version is 0x 5

work via V4L2

veye_xumm

@dan_lionking
Right. That's the result.
