Dear David-san
I have re-create the libcamera environment with the latest sources and trying IMX327 module.
I can normally make I2C access to IMX327 sensor, and maybe almost OK to display the image.
I see the ERROR messages.
Please check attached log file and give me the advice to correct the problem.
And I just copy the uncalibrated.json to imx290.json.
It would be great if you could show me your imx290.json file.
I appreciate your kind help in advance.
Best Regards,
NOMURA

Dear David-san
Thank you very much for your kind advice.
I'll try below according to your instruction and I'll report you the result soon.
The X'tal on my board, the clock-frequency=37.125MHz.
Shall I change the description in config.txt? (Anyway, I'll try two cases.)
I have one small question about the dtoverlay function.
When I connecting IMX378, the same die to IMX477 but different device ID, I remember I need to make the imx378.c modified from imx477.c then build it.
In case of IMX327, using the imx290.c but it seems different manner, it can work without build.
What is the difference between these two cases?
By the way, I can send you 3 kinds of IMX327 prototype modules of different FoV and the board to connect to Raspi and tinker board w/ IRCF as the gift for your kindness if you are interested in them.
And IMX378 AF/OIS module, too.
Actually I developed it in previous company as the reference design of IMX378 and other IMX sensors.
I can see excellent image of IMX378 on tinker board image tuned by myself with the help of Rockchip and also by qcam.
And hopefully I'd like to activate the AF function.
(Only manual focus adjust is available now.)
Best Regards,
NOMURA

Hello Nomura-san
Yes, I've been looking at the imx327 recently.
The latest Linux distributions for Raspberry Pi include a driver for imx290, and the same one appears to work for imx327. There is also a dtoverlay, in my /boot/config.txt I use:
dtoverlay=imx290,clock-frequency=74250000
Libcamera needs a CamHelper for the camera to work with the Pi and I have one ready to submit, only it's waiting on some other patches that are currently under review. But it shouldn't be too long.
I also have a tuning file, however, the module that I have here is of the "NoIR" variety, so no sensible colour tuning is really possible.
I'll submit it with the CamHelper. I believe they're Innomaker modules. Is this what you have or do you have something else?
Best regards
David
