Hello @ShaneCCC and @JerryChang
I have changed port-index to 0 from 2 in all places and tegra_sinterface to "serial_a"from serial_c but sill iam unable to get any video

I checked “v4l2-ctl --device /dev/video0 --all” in terminal and VI got enumurated as VI port 0

v4l2-ctl --device /dev/video0 --all

are you actually working with camera sensor on CSI-A ?

25

@JerryChang
Yes our sensors mipi lines are connected to CSI-A of Jetson Xavier

26

I would suggest to probe the signal to confirm the connection, and print out the configure from the csi/vi driver to confirm the configure.

27

Hello @ShaneCCC and @JerryChang
We also notice that in MIPI CSI-A clock lanes we are getting signals during initialization of driver and after booting process/ after initialization it goes low. while giving the v4l2 command clock comes for 2 pulse and goes low but data lanes have continuous pulses (image attached). scope_2 image shows mipi bus clk during driver initialization , Scope_3 image shows data lanes when v4l2 command is called. image scope_4 shows clock lanes when v4l2 command is called (only 2 pulses came and goes low).

@ShaneCCC
is the topology is proper for MIPI-CSI A port? do we want to make any changes in Pad settings?

Hello @ShaneCCC @JerryChang
Anything to add from your side for previous thread? also i made the following change in the device tree (Added CSI-Port and data lanes parameters) instead of port_Index by revering to the thread (Sensor detected and driver loaded but no /dev/video0 node - #14 by JerryChang) , now again sensor driver is loaded but when v4l2 command is called system freezes and restarts ( no logs in trace file).

{
host1x {
vi@15c10000 {
num-channels = <1>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
e3326_vi_in0: endpoint {
csi-port = <0>;
clock-lanes = <0>;
data-lanes = <1 2>;
bus-width = <2>;
remote-endpoint = <&e3326_csi_out0>;
};
};
};
};

  nvcsi@15a00000 {
  	num-channels = <1>;
  	#address-cells = <1>;
  	#size-cells = <0>;
  	channel@0 {
  		reg = <0>;
  		ports {
  			#address-cells = <1>;
  			#size-cells = <0>;
  			port@0 {
  				reg = <0>;
  				e3326_csi_in0: endpoint@0 {
  					csi-port = <0>;
  					bus-width = <2>;
  					remote-endpoint = <&e3326_ov5693_out0>;
  				};
  			};
  			port@1 {
  				reg = <1>;
  				e3326_csi_out0: endpoint@1 {
  					remote-endpoint = <&e3326_vi_in0>;
  				};
  			};
  		};
  	};
  };

};

Is the format is correct for CSI-A port connection?

33

Current VI driver should use port-index instead of csi-port.

34

Hello @ShaneCCC and @JerryChang
Still we were not anle to any image data , as of now following things are done

  • Video0 enumurated properly and driver probed properly
  • Sensor mode is seeted up properly and i2c registers are written properly to sensor
  • Start streaming function is invoked properly
  • We are using onboard oscillator , power and GPIO controls in the sensor and not using any power or clock from the Xavier , do we need to comment power and clock related things in driver and devictree file?
  • Since our camera sensor is connected to MIPI CSI A port we have changed, port-index to 0 from 2 in all places and tegra_sinterface to "serial_a"from “serial_c”
35

Did you check the trace log still the same?

37

Looks like the same VI/CSI didn’t receive any validate package from the bus.

@ShaneCCC can it happen because of any mis-configuration in device-tree file or is it because of im-proper data from the sensor side?

Both of them are possible.

Hello @ShaneCCC
we observed now after implementing all the changes , when v4l2 command is called and registers are written properly there transactions in mipi data lanes checked with oscilloscopes , but the clock lanes goes low and it goes high only after the interrupt ctrl+C, So no Clock transcation is happening. I also doubt whether by any chance Xavier pulls down the clock lane during v4l2 stream command? Also when calling GST-Launch there no transaction in both clock and data lane and showas message as follows

Correct me if iam wrong : I guess MIPI clock lane signal is generated from sensor (Image attached)image , but when the v4l2 stream command is called and data signal starts coming somehow the sensor clock lane goes low, is there any explanation you can provide?

The MIPI clock was control/output from the sensor. It could be sensor HW or configure incorrect.
