The second parallel port of the camera as the main function in colibri IMX6

[valentinryzhenk]

Hello,

I have custom board. It has two decoders for two different cameras. I need to configure their simultaneous work.

Standart
adv7280: adv7280@20 {
compatible = "adv7280";
reg = <0x20>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ipu1_csi0>;
clocks = <&clks 200>;
clock-names = "csi_mclk";
DOVDD-supply = <&reg_3p3v>;
AVDD-supply = <&reg_3p3v>;
DVDD-supply = <&reg_3p3v>;
PVDD-supply = <&reg_3p3v>;
csi_id = <1>;
mclk = <24000000>;
mclk_source = <0>;
status = "okay";
};

v4l2_cap_0 {
compatible = "fsl,imx6q-v4l2-capture";
ipu_id = <0>;
csi_id = <1>;
mclk_source = <0>;
status = "okay";
};

pinctrl_ipu1_csi0: ipu1grp-csi0 {
fsl,pins = <
MX6QDL_PAD_EIM_A17__IPU1_CSI1_DATA12 0xb0b1

};

};
But together they do not want to work. Although individually everything works. What did I do wrong?

Hi Valentin

unfortunately I am not familiar with this board, seems it is necessary to appropriately

configure VC (virtual channels), please check examples on

https://community.freescale.com/docs/DOC-328548

two camera work at the same time
