IMX462 sensor with Raspberry Pi 5

[Olli781]

Hello everyone,
I tried to run the following camera on a Raspberry Pi 5:
innomaker Raspberry Pi industrial camera module, STARVIS IMX462

Due to the built-in sensor, the camera would be well suited for astrophotography.
Unfortunately, the camera is not recognized despite the following entries in the config.txt:

Automatically load overlays for detected cameras

camera_auto_detect=0
dtoverlay=imx462,clock frequency=74250000

The standard camera with the IMX219 sensor is recognized without errors and works with the INDI Pylibcamera driver perfect.
Is it possible in principle to operate the IMX62 sensor with Astroarch?

Thank you, Oliver

Hi @Olli781,

sensor support does not depends directly on the distribution but rather if libcamera supports it or not. Do you happen to know if that sensor should be supported out of the box?

[Olli781]

Hi Mattia,

thank you very much for your reply. According to the manufacturer, libcamera supports the sensor. You just have to adapt the config.txt. Then the sensor should be recognized as IMX290. When reading the log file, the following line is also output:

rp1-cfe 1f00128000.csi: found subdevice /axi/pcie@120000/rp1/i2c@80000/imx290@1a

For better understanding, I have attached the config.txt and the log file.

hi @Olli781 I had a look at both libcamera and the rpi version of libcamera and I can't find any trace of the imx462, while I can see specific code for the imx290

I found this one => https://forums.raspberrypi.com/viewtopic.php?p=1946571#p1946571

can you try to set the overlay directly to imx290?

[Olli781]

Hi Mattia,

unfortunately, switching overlay directly to imx290 didn't work either. At the same time, I started a request to Innomaker Support. Here is the feedback:

The RPI linux kernel using the same driver for cmos sensor imx290,imx327 and imx462 so
the infomation show it is imx290 sensor is correct .
From the log file I can see the sensor was successfully registed as /dev/video0 and /dev/video1.
Please try to using :
$libcamera-hello -t 0
have a test and send me the test log.

The command “libcamera-hello -t 0” returned the following message

There seems to be a problem with the IPA module.

hey @Olli781 can you tell me what version of libpisp libcamera you have?

[MattBlack85]

libpisp is there, 1.0.6 I see

[Olli781]

Hi Mattia,

I did a little research on the internet and found the attached file. This must be copied to the following folder:
/usr/share/libcamera/ipa/rpi/pisp

The camera is then recognized and also runs in ekos/kstars without any problems.

Thank you again for your help and the great project.

Best regards
Oliver

hi @Olli781 the file should be available in the new version of libcamera, I am unsure when I will find the time to relase it, but hopefully it will be this week
