mxc_v4l_dqueue timeout error for adv7180 in i.MX6s processor

SheikAjith — Wed, 02 Aug 2023 03:46:29 GMT

Hello team,

We are working in analog camera adv7180 device prototype based on i.Mx6s module.

We are using kernel 6.1.1.We are now trying to bring camera up.

Camera used is MCC-5463 analog camera based on adv7180 sensor(parallel CSI). Resolution is 720x625

Following changes have been done in dts file

adv7180: camera@21 {
compatible = "adi,adv7180";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_adv7180>;
reg = <0x21>;
status = "okay";
pwn-gpios = <&gpio1 18 GPIO_ACTIVE_LOW>;
reset-gpios = <&gpio5 24 GPIO_ACTIVE_HIGH>;

interrupt-parent = <&gpio1>;
interrupts = <9 IRQ_TYPE_LEVEL_LOW>;

gpr = <&gpr>;
clocks = <&clks 201>;
clock-names = "csi_mclk";
DOVDD-supply = <&reg_3p3v>; /* 3.3v, enabled via 2.8 VGEN6 */
AVDD-supply = <&reg_3p3v>; /* 1.8v */
DVDD-supply = <&reg_3p3v>; /* 1.8v */
PVDD-supply = <&reg_3p3v>; /* 1.8v */
csi_id = <0>;
mclk = <24000000>;
mclk_source = <0>;
cvbs = <1>;
max_sensor = <4>;
lanes = <2>;

port {
adv7180_to_ipu1_csi0_mux: endpoint {
remote-endpoint = <&ipu1_csi0_mux_from_parallel_sensor>;
bus-width = <8>;
hsync-active = <1>;
vsync-active = <1>;
};
};
};

&ipu1_csi0_mux_to_ipu1_csi0 {
lanes = <2>;
bus-width = <8>;
};

&ipu1_csi0_mux_from_parallel_sensor {
remote-endpoint = <&adv7180_to_ipu1_csi0_mux>;
bus-width = <8>;
};

&ipu1_csi0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_decoder>;
lanes = <2>;
};

pinctrl_decoder: decodergrp {
fsl,pins = <

>;
};

These changes and all done and adv7180_tvin.c driver has been enabled in make menuconfig

With these changes. We have run the mxc_v4l2_capture application and this is the ouput

Can you get what is the reason for this error. I am completely struck up with this.

Hardware wise probed all possible lines. voltage supply, HSYNC,VSYNC, Data lines, pixelclock and all seems fine. So till CPU it seems fine.

But not sure why V4L2 app fails to capture. Even mxc v4l2 Overlay application also fails.

I have tried to capture the input video using gstream launcher but I am facing mxc_v4l_dqueue timeout error.

Please help with this.

Thanks in advance.
