imx8mp with sony imx412 and 4 lanes

pmliquify · ‎02-29-2024

Hi all,

Situation:

I developed drivers for the sony imx412 and imx327 camera modules. Both cameras are working fine with 2 lanes. The imx327 additionally works fine with 4 lanes. All tests are done on both camera ports of the imx8mp.

See my device tree files attached!

imx8mp.dtsi
+-> imx8mp-var-dart.dtsi
    +-> imx8mp-var-dart-dt8mcustomboard.dts
        +-> imx8mp-var-dart-dt8mcustomboard-vc-mipi-isi0.dts

Problem:

The imx412 doesn't even start streaming with 4 lanes. On neither camera port. Sometimes I get a first image. After that the stream stops and never delivers a second image. This first image contains half of all data. The bayer pattern seems "broken". I guess this is because only every second line of the image is transmitted.

Update: My latest tests

Sony IMX412 from Vision Components on Variscite imx8mp Evaluation Kit, Kernel 5.15.71
2 + 4 lanes always with pixelformat RG10

With 2 lanes I do get valid images with full resolution 4032x3040 and also with smaller resolutions. Everything is fine with 2 lanes.

With 4 lanes I found that I get valid images up to an image resolution of 2780x3040. When I increase the image width to 2781 and above the image isn't valid anymore. See example images.

In all cases I do get following log

mxc-mipi-csi2.0: Frame End events: 2
mxc-mipi-csi2.0: Frame Start events: 2
mxc-mipi-csi2.0: Non-image data after odd frame events: 0

mxc-mipi-csi2.0: Lost Frame End Error events: 0
mxc-mipi-csi2.0: Lost Frame Start Error events: 0
mxc-mipi-csi2.0: SOT Error events: 0

This leads me to believe, that the CSI receiver works fine, but the ISI is doing something bad.
Any suggestions?

Any help is highly appreciated. Any suggestions or advice on how to analyze the problem?

joanxie · ‎03-20-2024

did you try the settings I suggest to you one week ago?

joanxie · ‎03-03-2024

could you share

imx8mp-var-dart-dt8mcustomboard.dts

and all of other include dtsi files? check if the clock is available for 4 data lane

pmliquify · ‎03-04-2024

Yes of coarse, I attached the files to my first post. See above.

joanxie · ‎03-06-2024

what format do you use for capture? not raw data? and what command do you use to capture the data from imx412?

pmliquify · ‎03-06-2024

I do capture images with RAW10 (RG10) pixelformat. The screenshot is created with my self develop test app (https://github.com/pmliquify/v4l2-test). The test app debayers the image with opencv.

But I do get the capture problem as well with v4l2-ctl.

joanxie · ‎03-11-2024

since you use raw data, why don't you use ISP for this? if you need to use ISI, do you add raw10 format in the ISI driver?

https://github.com/nxp-imx/linux-imx/blob/lf-6.1.y/drivers/staging/media/imx/imx8-isi-fmt.c

pmliquify · ‎03-11-2024

Hi joanxie,

I will use the ISP once the system delivers images via the v4l2 interface. My current problem is, that I do not receive images in memory with the IMX412 and 4 lanes. I DO get images with 2 lanes but NOT with 4 lanes.

Which possibilities exist to debug my system?
How is it possible to see/debug if the csi receivers receives data?
How is it possible to see if the isi is receiving data?
Is it possible that I do not receive data, because of wrong csis-hs-settle, csis-clk-settle settings? How to determine the correct settings?

Any help is highly appreciated!

joanxie · ‎03-12-2024

for 2 data lane and 4 data lane, do you use the same video format, resolution? just change the data lane from 2 to 4? could you give me the logfile when you use capture command with data lane 4? also pls dump the mipi csi registers to check, for csis-hs-settle, csis-clk-settle, which is depends on your actual mipi frequency, you can try to set csis-hs-settle = <16>;

pmliquify · ‎03-27-2024

I set csis-hs-settle = <16>; => No success.

joanxie

you said your IMX412 can work with 2 lane, but why the dump error message for 2 lane settings? and pls check the register Gasket 0 Control Register (GASKET_0_CTRL), this register shouldn't be 0, you should set correct format for your camera, so pls check it
