IMX8MPLUS SENSOR CALIBRATION FILES

[venom]

Hi,
Currently i am working on imx415 camera sensor porting on imx8mplus ,i have customized my imx415 driver according to camera sensor porting guide.
What i don't have are the sensor calibration files. Now, even if i don't have calibration file is will my camera work and send data to ISP?? 
Is it really important that i have sensor calibration files??Can i skip that part or not??
For now, without any calbration files i cannot stream.I can see that it actually triggers a ioctl call "VIDIOC_QUERYCAP" in my sensor driver but after that i can see a isp driver log that enables streams and immediately disabling.  What might be the reason for this??.

LOG:

[ 194.089080] imx415 1-001a: Inside VIDIOC_QUERYCAP
[ 194.118862] enter isp_mi_stop
[ 195.511209] enter isp_set_stream 1
[ 212.626549] enter isp_set_stream 0

Thank you,
Regards Harsha.

Hello,

the answer is yes, you need the calibration files as explained in the ISP New Camera Sensor Porting and Integration Guide for i.MX 8M Plus EVK.

Hi,

While streaming, I can observe the following logs. Could you help me understand what the possible reasons for this behavior might be?

I am not receiving frame end at all.

Please modify the DTS node as:

Configure 266MHz clock on the second MIPI-CSI2 port:

+&mipi_csi_1 {

+      #address-cells = <1>;

+      #size-cells = <0>;

+

+      clock-frequency = <266000000>;

+      assigned-clock-parents = <&clk IMX8MP_SYS_PLL1_266M>;

+      assigned-clock-rates = <266000000>;

+

+      status = "okay";

+

+      port@1 {

+              reg = <1>;

+              mipi_csi1_ep: endpoint {

+                      remote-endpoint = <&jxf355_mipi_1_ep>;

+                      data-lanes = <2>;

+

+                      csis-hs-settle = <5>;

+                      csis-clk-settle = <0>;

+                      csis-wclk;

+              };

+      };

+};

Hi,
I am using only one csi port & my device tree configuration is as follows:

imx415_0: imx415_mipi@1a {
     compatible = "sony,imx415";
     reg = <0x1a>;
     clocks = <0x1a>;
     assigned-clocks = <0x1a>;
     assigned-clock-rates = <0x16E3600>;
     clock-names = "csi_mclk";
     status = "okay";
     csi_id = <0x00>;

port {
      imx415_0_ep: endpoint {
                   remote-endpoint = <&csi0_ep>;
                   clock-lanes = <0x00>;
                   link-frequencies = /bits/ 64 <360000000>;
                   max-pixel-frequency = <0x00 0x1dcd6500>;
                  data-lanes = <0x01 0x02 0x03 0x04>;
                  };
       };
};

csi@32e40000 {
       compatible = "fsl,imx8mp-mipi-csi\0fsl,imx8mn-mipi-csi";
       reg = <0x32e40000 0x10000>;
       interrupts = <0x00 0x11 0x04>;
       clock-frequency = <0x1dcd6500>;
       clocks = <0x02 0x10f 0x02 0x61 0x02 0x10d>;
       clock-names = "mipi_clk\0disp_axi\0disp_apb";
       assigned-clocks = <0x02 0xaa>;
       assigned-clock-parents = <0x02 0x41>;
       assigned-clock-rates = <0x1dcd6500>;
       bus-width = <0x04>;
       csi-gpr = <0x74>;
       gpr = <0x5b>;
       power-domains = <0x5b 0x01>;
       status = "okay";
       phandle = <0x10e>;

port {
          csi0_ep: endpoint {
                     remote-endpoint = <&imx415_0_ep>;
                     data-lanes = <4>;
                     csis-hs-settle = <0x0F>;
                     csis-clk-settle = <0x10>;
                   };
         };

};

If my sensor is in continuous mode does it work??
