Hi Loic and Team,
We have a SD820 SOM connected to a carrier board comprising two cci and csi ports.
I am not able to have both of them working together. Our device tree looks as below:
cci@a0c000 {
status = "ok";
i2c-bus@0 {
reg = <0>;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
camera_board@36 {
compatible = "ovti,oc0sa";
reg = <0x36>;
shtdwn-gpios = <&msmgpio 135 GPIO_ACTIVE_HIGH>;
fsin-gpios = <&msmgpio 29 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&camera_primary_default>;
clocks = <&mmcc CAMSS_MCLK0_CLK>;
assigned-clocks = <&mmcc CAMSS_MCLK0_CLK>;
clock-names = "xclk";
clock-frequency = <24000000>;
status = "okay";
port {
ovc0sa_1_ep: endpoint {
clock-lanes = <1>;
data-lanes = <0>;
remote-endpoint = <&csiphy0_ep>;
};
};
};
};
i2c-bus@1 {
reg = <1>;
#address-cells = <1>;
#size-cells = <0>;
camera_board@3c {
compatible = "ovti,ov5645";
reg = <0x3c>;
reset-gpios = <&msmgpio 23 GPIO_ACTIVE_LOW>;
enable-gpios = <&msmgpio 130 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&camera_secondary_default &camera_powerdown &camera_enable>;
clocks = <&mmcc CAMSS_MCLK1_CLK>;
assigned-clocks = <&mmcc CAMSS_MCLK1_CLK>;
clock-names = "xclk";
clock-frequency = <24000000>;
vdddo-supply = <&camera_vdddo_1v8>;
vdda-supply = <&camera_vdda_2v8>;
vddd-supply = <&camera_vddd_1v5>;
status = "ok";
port {
ov5645_2_ep: endpoint {
clock-lanes = <1>;
data-lanes = <0 2>;
remote-endpoint = <&csiphy1_ep>;
};
};
};
};
};
camss@a00000 {
status = "ok";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
csiphy0_ep: endpoint {
clock-lanes = <7>;
data-lanes = <0>;
remote-endpoint = <&ovc0sa_1_ep>;
status = "okay";
};
};
port@1 {
reg = <1>;
csiphy1_ep: endpoint {
clock-lanes = <7>;
data-lanes = <0 1>;
remote-endpoint = <&ov5645_2_ep>;
status = "disabled";
};
};
};
};
Problem statement:
When I have both the ports, i.e., port@0 status = “okay” and port@1 status= “okay”, I am not able to see the
/dev/media0 node, what could be the problem?
only when I have the port@0 status=“okay”, and port@1 status=“disabled” the /dev/media0 node is being populated.
Kindly let me know what is the fix to make both the camera devices working ?
