Tool/software:
We are using the OX05B1S image sensor in our design and have some questions regarding its configuration:
-
The datasheet specifies a link frequency of 960 Mbps per lane for achieving a resolution of 2592x1944 (5MP) at 60fps. However, in our device, we have set the link frequency to 480 MHz. Could you confirm if this setting is correct, or should it be adjusted to achieve the specified performance?
this is our device tree configuration:
max96714: max96714@28 {
compatible = "ovti,ox05b";
//compatible = "max96714";
reg = <0x28>;
clocks = <&clk_ox05b1s_fixed>;
clock-names = "inck";
pwdn-gpios=<&main_gpio0 1 GPIO_ACTIVE_LOW>;
port {
csi2_cam0: endpoint {
remote-endpoint = <&csi2rx0_in_sensor>;
link-frequencies = /bits/ 64 <480000000>;
clock-lanes = <0>;
data-lanes = <1 2 3 4>;
};
};
};
&csi0_port0 {
status = "okay";
csi2rx0_in_sensor: endpoint {
remote-endpoint = <&csi2_cam0>;
bus-type = <4>; /* CSI2 DPHY */
clock-lanes = <0>;
data-lanes = <1 2 3 4>;
};
};
2.Regarding the data lane configuration:
In our device tree, we have specified the data lanes as <1 2 3 4> and the clock lane as <0>.
The datasheet, however, mentions four data lanes starting from zero (<0 1 2 3>) and a single clock lane.
Could you please clarify whether the data lane indexing we have used in the device tree is valid?
