iMX8QXP OV5647_mipi problem. Help please

draven — Sat, 01 Feb 2020 15:23:14 GMT

Hi I have iMX8QXP kit and I want to get stream from ov5647 camera.

DISTRO = fsl-imx-wayland.

My ov5647 camera's pin connected to :

MIPI_CSI0_ACM_MCLK_OUT MIPI_CSI0_MCLK_OUT ALT0

MIPI_CSI0_CKN                                        MIPI_CSI0_CLK_N                   ALT0
MIPI_CSI0_CKP                                        MIPI_CSI0_CLK_P                    ALT0
MIPI_CSI0_DN0                                        MIPI_CSI0_DATA0_N                ALT0
MIPI_CSI0_DN1                                        MIPI_CSI0_DATA1_N                ALT0
MIPI_CSI0_DN2 MIPI_CSI0_DATA2_N                ALT0

MIPI_CSI0_DN3 MIPI_CSI0_DATA3_N ALT0
MIPI_CSI0_DP0 MIPI_CSI0_DATA0_P ALT0
MIPI_CSI0_DP1 MIPI_CSI0_DATA1_P ALT0
MIPI_CSI0_DP2 MIPI_CSI0_DATA2_P ALT0
MIPI_CSI0_DP3 MIPI_CSI0_DATA3_P ALT0

But I2C pins not connected. Is it problem? Can I get datas from camera without init via i2c?

So I can't find these pins (with pad signal names) in ./include/dt-bindings/pinctrl/pads-imx8qxp.h and if I write these pins pad format I get error instead of write MIPI_CSI0_ACM_MCLK_OUT. I think this pins dedicated and I can't mux. I can use directly without change scfw.

So my dts file about mipi csi camera :

-------------------------------------------------------------------------

Then I open ov5647_mipi support via make menuconfig :

make menuconfig > Device Drivers > Multimedia Support > V4L platform devices > MXC Camera/V4L2 RPR Features Support > Omnivision ov5647 camera support using mipi > (*). I add y to here.

Than I boot, there is no new video in /dev. (with or without ov5647 driver not change video size. There are video12 and video13)

And I change Omnivision ov5647 camera support using mipi to m (build module) and I insmod ov5647_camera_mipi.ko

module loaded and strace like that :

now I seems modules : root@imx8qxpmek:/# find -name "ov5647" ./sys/bus/i2c/drivers/ov5647_mipi ./sys/firmware/devicetree/base/i2c@37230000/ov5647@36 ./sys/firmware/devicetree/base/i2c@58226000/ov5647_mipi@36 ./sys/module/ov5647_camera_mipi

and when ls /dev there is two /dev/video now. (video0 and video1).

Why there is two video channel now?

Also there is an error about my dts file. What is that :

root@imx8qxpmek:/# dmesg | grep ov5

I am waiting for some help.

Hi berat

one can look at mipi-csi ov5640 example

fsl-imx8qxp-mek-mipi-ov5640.dts\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel

driver description in sect.6.1.2 Omnivision Camera attached Linux Manual.

If not using i2c, one can try to remove i2c initialization in driver

ov5640_mipi_v3.c\imx8\platform\media\drivers - linux-imx - i.MX Linux kernel

Best regards
igor

I delete all things which about I2C. Also I attachted here. Please look.

I convert driver to yes from module. And it seems start correctly.

But I can't get image and show from LVDS panel.

Also I attach my gstreamer test.

Now I am not sure mipi-cs2 ov5647 camera is working or not. How can I test (show LVDS)? And which gstreamer code I should use?

My last output from gstream and process stuck last function and wait there.
