I have compile my camera driver and try to test it from my target board i.MX6Q I am facing with

probe of 1-001a failed with error -16

camera_name: camera_name@1a {     compatible = "camera,camera_name";     reg = <0x1a>;     inck-name = "mclk";     xvs-output-len = <8>;     xclr-gpio = <&gpio1 6 1 GPIO_ACTIVE_LOW>;     pwn-gpios = <&gpio1 6 1>;     clock-names = "csi_mclk";     DOVDD = <&reg_1p8v>;     AVDD = <&reg_2p9v>;     DVDD = <&reg_1p2v>;     rst-gpios = <&gpio1 6 1>; /* xclr */         ipu_id = <0>;                    csi_id = <0>;     mclk = <37125000>;     mclk_source = <0>;     lanes = <4>; };

But I couldnt understand what this error is saying and I couldnt find any information about it ? Do you have any suggestion ?  .I would be very appreciated .

Hi Mustafa

one can try to debug it using Chapter 20 MIPI CSI2 Driver attached Linux Manual and

AN4553 Using Open Source Debugging Tools for Linux on i.MX Processors

Thanks @igorpadykov the error massage  meanings are simply is mentioned at errno-base.h  in the system. After look at this I write pr_info(); function to the device driver  to figure out at which part I have faced with the problem .
