ADV7180 i.MX6

I have some problems with this chip!

I'm using the BSP imx-3.14.52-1.1.0_ga

 

1) First configuration

AD7180 + iMX 6Quad

CMA=260M

 

Device Tree
adv7180: adv7180@21 {
compatible = "adv,adv7180";
reg = <0x21>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ipu1_6>;
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 */
pwn-gpios = <&gpio3 19 0>;  /* put on not used pin */
csi_id = <0>;
mclk = <24000000>;
mclk_source = <0>;
cvbs = <1>;
};

The command

gst-launch-1.0  imxv4l2src  ! imxv4l2sink

all works!

 

 

2) Second configuration

AD7180 + iMX 6SoloX

CMA=160M

 

&csi1 {
status = "okay";
port {
csi1_ep: endpoint {
remote-endpoint = <&adv7180_ep>;
};
};
};
adv7180: adv7180@21 {
compatible = "adv,adv7180";
reg = <0x21>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_csi_2>;
clocks = <&clks IMX6SX_CLK_CSI>;
clock-names = "csi_mclk";
DOVDD-supply = <&reg_3V3>; /* 3.3v, enabled via 2.8 VGEN6 */
AVDD-supply = <&reg_3V3>;  /* 1.8v */
DVDD-supply = <&reg_3V3>;  /* 1.8v */
PVDD-supply = <&reg_3V3>;  /* 1.8v */
pwn-gpios = <&gpio3 19 0>;  /* put on not used pin */
csi_id = <0>;
mclk = <24000000>;
mclk_source = <0>;
cvbs = <1>;
status = "okay";
port {
adv7180_ep: endpoint {
remote-endpoint = <&csi1_ep>;
};
};
};

 

pxp_v4l2_out {
compatible = "fsl,imx6sx-pxp-v4l2", "fsl,imx6sl-pxp-v4l2";
status = "okay";
};

The command

gst-launch-1.0  imxv4l2src  ! imxv4l2sink

 

doesn't work!

 

If I try /unit_test/pxp_v4l2_out_test.sh

 

I obtain:

I checked the kernel config and I have enable all required modules.

 

Can anyone help me to resolve this problem?
