Tool/software:
Hi Team,
We have a working ar1335 camera module integrated on TI-AM625 Starter Kit with processor SDK Version: 08.06.00.42. Now we have ported the camera driver to processor SDK Version: 09.02.01.10.
I have done the following changes in the dtso file and camera driver.
DTSO:
/dts-v1/;
/plugin/;
#include <dt-bindings/gpio/gpio.h>
&{/} {
clk_ar1335_fixed: ar1335-xclk {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <24000000>;
};
};
&main_i2c2 {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
i2c-switch@71 {
compatible = "nxp,pca9543";
#address-cells = <1>;
#size-cells = <0>;
reg = <0x71>;
/* CAM port */
i2c@1 {
#address-cells = <1>;
#size-cells = <0>;
reg = <1>;
ar1335: camera@42 {
compatible = "aptina,ar1335";
reg = <0x42>;
clocks = <&clk_ar1335_fixed>;
clock-names = "xclk";
port {
csi2_cam0: endpoint {
remote-endpoint = <&csi2rx0_in_sensor>;
link-frequencies = /bits/ 64 <500000000>;
clock-lanes = <0>;
data-lanes = <1 2>;
};
};
};
};
};
};
&csi0_port0 {
status = "okay";
csi2rx0_in_sensor: endpoint {
remote-endpoint = <&csi2_cam0>;
bus-type = <4>; /* CSI2 DPHY. */
clock-lanes = <0>;
data-lanes = <1 2>;
};
};
Driver:
- static int ar1335_remove(struct i2c_client *client)
+ static void ar1335_remove(struct i2c_client *client)
The driver loaded successfully and created the video nodes. But I could get the streaming.

Do I need to change anything in the driver source for the latest processor SDK ?
Could you please provide some pointers to debug this issue.
