This camera sensor is very useful for astronomy with good sensitivity and low read noise.
Now to make that work, there are few important controls missing from the V4L2 driver.
For start, the single most important feature is to be able to take one single frame with defined exposure time as opposed to continuous video stream operation.
Gain setting and other options will be nice to have. But at least can be controlled via I2C script for now.

I have to admit I do not have much linux experience, and node driver development experience, but there are already few examples like the integration of the rpi HQ camera in the INDI library.

Its entirely possible that using of the V4L2 is not even the right way and using of the raspicam or other approach will be more suitable. I have to dig into it.

I will report my progress here and if anyone has something to contribute please let me know

@veye_xumm Perfect, thank you very much for your support. It is now working.

@veye_xumm Hello, I have continued with the debugging turned on the TRACE in the driver and added few debug messages.

It looks like the driver does not get correct response to this:
ret = veyecam2m_read_reg(veyecam2m, VEYECAM2M_MODEL_ID_ADDR, &device_id);
if (ret) {
dev_err(&client->dev, "probe failed \n");
return -ENODEV;
}

I have read about the http://wiki.veye.cc/index.php/RaspberryPI_I2C_confilict_problem ..is this still problem (iam not using DSI display)?. Also this solution recommends to rewire the I2C. At which I2C bus the V4L2 driver actually expects to have the module?

I have also tried to disable the i2c_arm in the startup config, but no help either.

@veye_xumm
Thank you for the further information. Yes Iam using rpi 4b.
I have tried the i2cdetect fresh after start of the respberry
astroberry@astroberry:~ $ i2cdetect -y 10
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
No device is found with 3b address.

However when I execute the:
astroberry@astroberry:~/raspberrypi/i2c_cmd/bin $ ./camera_i2c_config
setting GPIO for board revsion: c03114
4B(1G/2G/4G/8G)
Set state of 133 to 1
Use i2c-10 for the sensor (-y 10)

Then the i2cdetect finds the device:
astroberry@astroberry:~ $ i2cdetect -y 10
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- 3b -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

However the dmesg still shows:
astroberry@astroberry:~ $ dmesg | grep veye
[ 6.523877] veyecam2m: loading out-of-tree module taints kernel.
[ 6.646795] veyecam2m 10-003b: probe failed

[ 31.835125] veyecam_vdig: disabling

Do I need to add the camera_i2c_config somewhere manually that it is executed at every startup before starting of the driver?

I have tested various i2c settings and all seems to reponds as expected so the i2c but definitely works.

On the first day when I got the camera, I was by mistake using the ./cs_mipi_i2c.sh, which is for the CS series, but that was never getting me some proper response. Could it be however that something is misconfigured? I tried for example the ./cs_mipi_i2c.sh -w -f sysreset at that time.

@veye_xumm

OK, I have tested something that worked before to check the camera function and connection:

./veye_raspivid -t 5000 -o ~/tes1t.h264
camera num -1
Hardare version: c03114
mmal: mmal_component_enable w 1920 h 1080 fps 30

raspipreview_create com
mmal: Splitter has 4 output port,you could use num 2,3 for extend

It does not do more at this point, just stops there and no video is recorded. Camera is responding to the I2C commands however.

I have tried to uninstall the V4L2 driver and restart and after that recording works:
I have just executed this one command after the raspberry was restarted (no I2C commands to configure, etc)
./veye_raspivid -t 5000 -o ~/tes1t.h264
camera num -1
Hardare version: c03114
mmal: mmal_component_enable w 1920 h 1080 fps 30

raspipreview_create com
mmal: Splitter has 4 output port,you could use num 2,3 for extend
mmal: running now!!
mmal: running stop!! 0

Video is recorded as expected.

Are there maybe some logs somewhere to see more exactly vhy the V4L2 diver refuses to work? Also when the V4L2 is active, should it prevent the camera to be used othewise, for example to record the video or stream?

Thank you

@veye_xumm Thank you for checking. I have tried the updated drivers. Its not working, but least the driver tries to start. I have tried to compile driver locally, but it is the same result.

What could be still wrong?

Hello,

I have tried to follow the guide on http://wiki.veye.cc/index.php/V4L2_mode_for_Raspberry_Pi, but unfortunatelly i did not managed to get it to work.

I will post some info about my system and steps that I tried:
lsb_release -a ... Raspbian GNU/Linux 10 (buster)
uname -a ... Linux astroberry 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux
Camera and I2C is enabled in raspi-config
I do not use the display, raspberry is controlled via vnc
Software toolkit is downloaded, when i try veye_raspivid -t 5000 -o ~/test.h264, video is recorded, camera works
./enable_i2c_vc.sh was executed

./camera_i2c_config
setting GPIO for board revsion: c03114
4B(1G/2G/4G/8G)
Set state of 133 to 1
Use i2c-10 for the sensor (-y 10)

./veye_mipi_i2c.sh -r -f hdver
hardware version is 0x 6

./veye_mipi_i2c.sh -w -f videoformat -p1 NTSC
w videoformat is NTSC

./veye_mipi_i2c.sh -r -f cameramode
r cameramode is 0x 0

./veye_mipi_i2c.sh -r -f boardmodel
Board model is VEYE-MIPI-IMX327S

./veye_mipi_i2c.sh -r -f sensorid
r sensor id is IMX 462; ONE board

For V4L2 installation i followed the staps according to the guide:
wget https://github.com/veyeimaging/raspberrypi_v4l2/releases/latest/download/raspberrypi_v4l2.tgz
tar -xzvf raspberrypi_v4l2.tgz
cd raspberrypi_v4l2/release/
chmod +x *
sudo ./install_driver.sh veyecam2m

After restart I tried:
dmesg | grep veye ... no reponse (empty text)
ls /dev/video0
ls: cannot access '/dev/video0': No such file or directory
cannot open it in vlc as well

I have tried to compile drivers locally, same result as with precompiled drivers. I have found same verson as as my system in the pre-compiled drivers.

Some settings may impact device functionality. See link above for details

uncomment if you get no picture on HDMI for a default "safe" mode

#hdmi_safe=1

uncomment this if your display has a black border of unused pixels visible

uncomment the following to adjust overscan. Use positive numbers if console

goes off screen, and negative if there is too much border

#overscan_left=16
#overscan_right=16

#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

Uncomment some or all of these to enable the optional hardware interfaces
