I need wait for clear sky to test and provide feedback
Finally tested, for gain value 20 it is looks pretty same with color sensor with ISP, but background no so black as for color sensor.
For me this issue resolved, attached examples to compare (10 seconds stacks)
IMX462 mono
IMX462 color with ISP
@veye_xumm
Yes, version is 1.09 after upgrade
@veye_xumm
Hi, thank you for firmware update.
Just to double check, is HCG mode always turn on now?
Also for register 0x3009 I got value 0xffff instead ox11 but seems like HCG enabled anyway.
I need wait for clear sky to test and provide feedback
PS:
After upgrade at the end it writes: "Failed to write register" message but upgrade done , can I just ignore it?
@veye_xumm
By the way, I see that I can read registers of camera by snsreg command but can't find how to write.
Is it possible set register 0x3009 value to 0x11 to enable HCG mode?
@veye_xumm
With metime and mgain parameters I increased sensitive, but it more noisy than color sensor with ISP, anyway issue with pixel format fixed for me, thank you.
@veye_xumm
Thanks, it means only manual gain/exposure mode.
I have one more question but it is a little bit out of topic.
Yesterday I tried to take pictures of the night sky to compare with 462 color sensor, even with high gain value stars are not bright as for the same parameters on 462 color (but mono should be more sensitive) . It looks like there is no switching between LCG and HCG modes or I need to tune some other parameters.
Can you advise what could be tuned for this case?
@veye_xumm
One more question, I see now all parameters like gain and exposure managed by libcamera software according to json file, Can we use internal camera ISP for it as before?
@veye_xumm
Hi, I noticed that version of libcamera different on my screenshot (it 0.2.0 but I installed 0.3.0)
I uninstalled rpicam-apps and rebuild it from source code again and it uses my version of libcamera now.
if execute rpicam-still -v I have next error:
In commit I see added json file only to vc4 folder (for RPi4) , can we add it to pisp folder (for RPi5) it should have name : "mvcam_mono.json"? it has different format and can't use same file from vc4.
Also I managed start video by this command:
rpicam-still --tuning-file /source/libcamera/src/ipa/rpi/pisp/data/uncalibrated.json -t 0
and it works!
But better run it without additional parameters
Thank you.
@veye_xumm
Hi, it helped but I had to use 1.0.6 tag of libpisp, with the latest version I had compile errors.
Now for command : rpicam-hello -v
I have this error:
I used set media script before:
Maybe forgot something else.
@veye_xumm
Hi, thank you for update.
I'm stuck with compiling libcamera now, with same error as here : https://github.com/raspberrypi/libcamera/issues/151
Did not find solution yet, probably need play with source code, will let you know if any updates.

Hi, I had similar issue with another camera vendor and it was related to overlay file which was from RPi4.
And fixed by replacing :
cam0 = <&i2c_frag>, "target:0=",<&i2c_vc>
to
cam0 = <&i2c_frag>, "target:0=",<&i2c_csi_dsi0>
Did you install driver from "release" folder or built it manually from source code?
if manually you need use dts(dtbo) file from rpi-6.1.y-bookworm folder.
Correct camera location should be:
/axi/pcie@120000/rp1/i2c@88000/veyecam2m@3b
/axi/pcie@120000/rp1/i2c@80000/veyecam2m@3b
As I see your second camera on ic2@70000 similar as I had with wrong overlay file.
@veye_xumm
Thank you for documentation, I used wrong algorithm to decode 10 bit packed format.
According to doc:
10-bit camera modes pack 4 pixels into 5 bytes. The first 4 bytes contain the 8 most significant bits (MSBs) of each pixel, and the final byte contains the 4 pairs of least significant bits (LSBs).
I fixed it and can open raw image from python, but anyway need find way how to decode video in real time, because now decode one frame is about 3 seconds.
Same Image as above:
@alex_ai said in IMX462M pixelformat on RPi5:
Hi @veye_xumm
Hi, I managed to decode mipi packed raw format in rawfile_to_opencv_show.py file and seems like problem is not only in pixel format. If you look to image bellow : it has 6 same small areas which overlaps each other
Also enabled "test image" in camera configuration and it looks similar:
It is most probably driver issue or hardware issue.
What is else I can try to modify?
Hi @veye_xumm
I reinstalled driver from fresh sources and updated format to Y10P in media_setting_rpi5.sh.
Now command : v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat='Y10P' --stream-mmap=3 --stream-count=1 --stream-to=y10-1920x1080.raw
saves file but I can't open it, what application should I use? all my applications which supports raw formats could not recognise this file.
Also I tried open stream in qv4l2 application, it could open but video image broken
Hi, I'm trying to get image from IMX462M on RPi5.
Driver Installed, I can use mv_mipi_i2c.sh tool but can't get image.
According to documentation for v4l2-ctl I should set pixelformat='Y10 ' but seems like v4l2-ctl doesn't support it (returns: The pixelformat 'Y10 ' is invalid) .
v4l2-ctl --list-formats-ext returns only next supported mono formats:
with 'Y10P' it returns : VIDIOC_STREAMON returned -1 (Invalid argument)
Could you please advise how to fix it?

@alex_ai said in New Raspberry pi 5 support:
any chances use configuration script ./veye_mipi_i2c.sh on RPi5?
No. Just pay attention to i2c bus number.
I think answer was "yes" but with parameter -b. I could not execute from bin dir because it compiled to another OS, so compile i2c_read, i2c_write from source code fixed my issue.
@veye_xumm thank you for help and support!
@alex_ai said in New Raspberry pi 5 support:
I managed open stream via gst-launch-1.0 v4l2src ... but my application uses OpenCV it could not open device, @veye_xumm did you try it on RPi5 with python samples?
In my case OpenCv was without Gstreamer plugin and I had to build it from source code with parameter : -D WITH_GSTREAMER=ON and now issue resolved.
Also after every RPi restart have to run script: ./media_setting_rpi5.sh veyecam2m
@veye_xumm any chances use configuration script ./veye_mipi_i2c.sh on RPi5?

@veye_xumm Hi, Also trying to use IMX462 on RPi5 and after installing drivers it was detected correctly by rpi5 scripts but can't play it by VLC or my program which use setting on RPi4 like this:
device: v4l2src device=/dev/video0Could you please advise what I'm doing wrong?

Hi,
Any plans for MIPI IMX662 module?
I'm using VEYE-MIPI-IMX462 on raspberry Pi for meteors detection and will be happy to test/compare this new sensor.
Thanks.
