OK8MP-C camera Image missing line

[zhichao_hu]

I can use imx8 to obtain the image successfully, but the original image(yuv422-8bit) has problems such as missing lines and wrong line positions. Has anyone encountered similar problems?

This camera is ti964, and the camera register configuration is normal. I can read from the 964 chip that the output rows and columns are consistent with those of the camera.

Is there any way to help me locate this problem? I don't know what caused the error of the original data line of the image

Thanks, I have solved this problem

did you use 8QM board? and which dts file do you use? how did you change it? pls send the patch to check

I use forlinx imx8MP OKMX8MP-C.

I change dts i2c2 part ov5645 to :

&i2c2 {

clock-frequency = <100000>;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_i2c2>;

status = "okay";

jh1mp_0: jh1mp_mipi1@32 {

compatible = "ti,jh1mp";

reg = <0x32>;

pinctrl-names = "default";

pinctrl-0 = <&pinctrl_csi0_pwn>, <&pinctrl_csi0_rst>;

clocks = <&clk IMX8MP_CLK_IPP_DO_CLKO2>;

clock-names = "xclk";

assigned-clocks = <&clk IMX8MP_CLK_IPP_DO_CLKO2>;

assigned-clock-parents = <&clk IMX8MP_SYS_PLL2_200M>;

assigned-clock-rates = <20000000>;

csi_id = <0>;

enable-gpios = <&gpio3 20 GPIO_ACTIVE_HIGH>;

reset-gpios = <&gpio3 19 GPIO_ACTIVE_LOW>;

clock-frequency = <20000000>;

mclk = <20000000>;

mclk_source = <0>;

mipi_csi;

virtual-channel;

status = "okay";

port {

jh1mp_mipi_0_ep: endpoint {

remote-endpoint = <&mipi_csi0_ep>;

data-lanes = <1 2 3 4>;

clock-lanes = <0>;

link-frequencies = /bits/ 64 <336000000>;

};

};

};

};

what do you mean "I can use imx8 to obtain the image successfull"? this isn't nxp board, what bsp version do you use? did you have any logfile to share?
