IMX8MP: Cant get data from IMX385 sensor

Egor-G — Fri, 28 Apr 2023 08:21:18 GMT

Hello. I'm trying to get data from Sony IMX385 sensor, connected to CSI of IMX8MP. I modified similar IMX290 driver to setup sensor ( I also tryied ready IMX385 drivers found on github). I also modified imx8-isi-cap.c and imx8-isi-fmt.c to enable RAW12 format. I added

{
.name = "SRGGB12",
.fourcc = V4L2_PIX_FMT_SRGGB12,
.depth = { 16 },
.color = MXC_ISI_OUT_FMT_RAW12,
.memplanes = 1,
.colplanes = 1,
.mbus_code = MEDIA_BUS_FMT_SRGGB12_1X12,
.align = 3,
},

in mxc_isi_out_formats[] and

{
.name = "SRGGB12",
.fourcc = V4L2_PIX_FMT_SRGGB12,
.depth = { 16 },
.memplanes = 1,
.colplanes = 1,
.align = 2,
},

in mxc_isi_src_formats[], and changed *mxc_isi_get_src_fmt function to:

struct mxc_isi_fmt *mxc_isi_get_src_fmt(struct v4l2_subdev_format *sd_fmt)
{
u32 index;

/* two fmt RGB32 and YUV444 from pixellink */
if (sd_fmt->format.code == MEDIA_BUS_FMT_YUYV8_1X16 ||
sd_fmt->format.code == MEDIA_BUS_FMT_YVYU8_2X8 ||
sd_fmt->format.code == MEDIA_BUS_FMT_AYUV8_1X32 ||
sd_fmt->format.code == MEDIA_BUS_FMT_UYVY8_2X8 ||
sd_fmt->format.code == MEDIA_BUS_FMT_YUYV8_2X8)
index = 1;
else if(sd_fmt->format.code == MEDIA_BUS_FMT_SRGGB12_1X12)
index = 2;
else
index = 0;
return &mxc_isi_src_formats[index];
}

Camera connected to CSI1:

&i2c5 {
clock-frequency = <100000>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_i2c5>;
status = "okay";

compatible = "sony,imx385";

status = "okay";

port@1 {
reg = <1>;

remote-endpoint = <&imx385_mipi_1_ep>;
data-lanes = <2>;
csis-hs-settle = <13>;
csis-clk-settle = <2>;
csis-wclk;
};
};
};

&isi_0 {
status = "okay";
interface =3 0 2>;

cap_device {
status = "okay";
};
};

&isi_1 {
interface = <2 0 2>;
};

&cameradev {
status = "okay";
};

Dmesg output:

When I call:

v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG12 --stream-mmap --stream-to=/tmp/test --verbose

I get:

But no data get from the sensor. Or, sometimes some bytes going from sensor but fps is too slow:

Could you help me to find the problem

Hi @Egor-G,

I hope you are doing well.

->Please make sure of the connection.
->Please try to capture the image by given below command.

v4l2-ctl --device /dev/video0 --set-fmtvideo=width=2688,height=1520,pixelformat=BG10
v4l2-ctl --device /dev/video0 --stream-mmap --stream-to=frame.raw --stream-count=1

->Please set the format, resolution, pixel, etc.. as per requirements.

I hope this may help!

Thanks & Regards,
Dhruvit Vasavada

Nothing works. Still no any data. I checked all connection and rewrite driver for raspberry pi. On raspberry pi camera send data, on IMX8 nothing with same driver.

Does someone know Is IMX8MP ISI and ISP accept RAW10/RAW12 packed format? In isp-vvcam/src/vvcam/v4l2/video/video.c defined only not packed formats

Hi @Egor-G,

I hope you are doing well.

Q)Is IMX8MP ISI and ISP accept RAW10/RAW12 packed format?
->The chip(8mp) supports two 4-lane MIPI CSI2 camera input.
->When used in conjunction with output to the ISP, the RAW8, RAW10, RAW12, and RAW14 image formats are supported.

I ckecked all connection - ok. Does someone have really working drivers (imx290.c, imx8-isi-cap.c, imx8-csi2-sam.c and etc) even for IMX290 sensor? It looks like some configuration is wrong.

IMX385 is very similar to IMX290. IS there someone who have working IMX290 on IMX8MP? There is imx290 driver in kernel tree and also there is a modified version for raspberry pi.

Hi @Egor-G,

-> If it seems configuration problem, One should use the latest BSP version to have updated drivers as well as firmware, Please check the same with the latest Linux BSP.

Q) IMX385 is very similar to IMX290. IS there someone who have working IMX290 on IMX8MP? There is imx290 driver in kernel tree and also there is a modified version for raspberry pi.
-> One can get this modified driver in the latest BSP at the below-given location for Sony IMX290 CMOS Image Sensor Driver.
<Linux_src_code>/drivers/media/i2c/imx290.c

I hope this information helps!
