Yes, both of them are “not” must have to implement functions.
You said before that they matter, my head is confused :))
Got my video0!!! There was a problem with channel.c where my debug comment interfered with a continue. So far so good.
Thank you a lot for now Shane. :)) You were a great help.
Now the real problem begins, I have to configure video0 such that it’ll be able to get video stream from our pre-configured camera.
While configuring for the specific video device, I know I need to change tegra210-camera-e3326-a00.dtsi
But do I also need to make any modification in ov5693.c/ov5693.h ?
Thank you! :)
(Do I need the CSI lanes connected? Camera is still not connected while I do these tests)
Tried
v4l2-ctl --list-devices
To see if the device is registered properly.
then
v4l2-ctl -d /dev/video0 --list-formats-ext
To see what resolutions are enabled.
The lowest-level capture with v4l2-ctl
v4l2-ctl --stream-mmap --stream-count=100 -d /dev/video0
first one outputed;
nvidia@tegra-ubuntu:~$ v4l2-ctl -d /dev/video0 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Index :0
Type : Video Capture
Pixel Format :'RG10'
Name : 10-bit Bayer RGRG/GBGB
And the others outputed nothing.
There were a lot of dmesg messages however, none of them included your PXL_EOF.
dmesg | grep PXL_EOF returned nothing.

- Looks like the i2c code from the driver not remove clean still saw the i2c access no ack message.
- Did you probe the MIPI signal to make sure the device was output validate data to MIPI bus.
- enable the debug print at csi2_fops.c to print the error status.
Thank you Shane. But my camera is still not connected while I do these tests.
Can you please tell me the correct commands to test if /dev/video0 works correctly, for both with camera and without camera.
You can’t test without camera.
Have a check below doc for the command to capture image from video input device.
nvidia@tegra-ubuntu:~$ v4l2-ctl --list-devices
VIDIOC_QUERYCAP: failed: Inappropriate ioctl for device

vi-output, my_in 6-0036 (platform:54080000.vi:2):

/dev/v4l-subdev1
/dev/v4l-subdev0
Is this normal for pre-configured camera? (Camera is still not connected, trying to figure out drivers without it.

i2c errors are all gone now, but still get
vi 54080000.vi: mipi calibration failed
vi 54080000.vi: calibration failed -110 error
tegra_mipi_cal 700e3000.mipical: Mipi cal timeout,val:67a1, lanes:400000
You can ignore the calibration message if your output resolution is not much higher.
Also the can ignore the “VIDIOC_QUERYCAP: failed: Inappropriate ioctl for device” message.
i want to change pixel_t = “bayer_bggr”; -----------> yuv422 format
i want to change output depth 10bit -----------> 8bit;
how to configure the device tree file? which files do I need to configure?
Have a reference to below topic for YUV sensor.

Thanks Shane. I checked them, but still have some questions.

What are the “must” be correct parameters for /dev/video0 to be configured correctly? There are a lot of parameters here and in the sensor programming guide, but I dont think all are necessary.

I think the “tegra-camera-platform” device-tree is what matters right? Are i2c@546c0000–>my_video_in@01 parameters are only used for configuring the camera? Or are they used in defining the /dev/video0 as well?
- If the modeX matters for not just configuring the camera, but also configuring the video stream, how are modeX decided? Do I need to specifically set the mode somewhere, or does JetsonTx1 select the most appropriate mode itself?
Thank you very much.
For your case below must be correct.

Hello Shane. Thank you again.
I gave numbers for each question, If you can answer them referring to numbers I’d be really happy.
Thanks for all the help and patience you’ve shown to us.
mode0 { // OV5693_MODE_2592X1944
mclk_khz = "24000";
num_lanes = "4";
tegra_sinterface = "serial_a";
discontinuous_clk = "yes";
dpcm_enable = "false";
cil_settletime = "0";
...

};
As I said before, we’re using a 4-lane MIPI CSI-2 yuv422 camera input. We’ve checked the Sensor Programming Guide configuration for lanes, and it is serial_a and num_lanes=4 in the modeX.
1)But what confuses us is that what are these csi-port and bus-width then?(e3326_vi_in0, e3326_csi_in0, e3326_ov5693_out0) Do we need to modify this as well? (I guess so)
vi {
num-channels = <1>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
status = "okay";
e3326_vi_in0: endpoint {
csi-port = <2>;
bus-width = <2>;
status = "okay";
remote-endpoint = <&e3326_csi_out0>;
};
};
};
};
nvcsi {
num-channels = <1>;
#address-cells = <1>;
#size-cells = <0>;
channel@0 {
reg = <0>;
status = "okay";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
status = "okay";
e3326_csi_in0: endpoint@0 {
csi-port = <2>;
bus-width = <2>;
status = "okay";
remote-endpoint = <&e3326_ov5693_out0>;
};
};
e3326_vi_in0, e3326_csi_in0, e3326_ov5693_out0. They all use;
csi-port = <2>;
bus-width = <2>;
2)Is this okey for a 4-lane, mipi csi2 camera? I think we need to change them.
3)We still don’t know how to select the mode of our choice. How do we select the mode we want?
The csi-port and bus-width must be correct for the vi/nvcsi scope too.
CSIA is 0 CSIF is 5 bus-width the same with the lane number. For your case should be like below.
csi-port = <0>;
bus-width = <4>;
How does the mode selection works? Any knowledge on that one Shane? At the worst case, we’ll delete all the other mode’s and just stick with mode0 of our choice.
Thank you.
The width and high can request from the application layer and vi/sensor driver handle it.
It’s better to support one mode to reduce the problem.
