When I use the cmd show below, I cannot get image.

cmd: v4l2-ctl --set-fmt-video=width=1280,height=768,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video0

dmesg:
[ 502.072933] tegra194-vi5 15c10000.vi: corr_err: discarding frame 0, flags: 128, err_data 131072
[ 504.698948] tegra194-vi5 15c10000.vi: no reply from camera processor
[ 504.699088] tegra194-vi5 15c10000.vi: uncorr_err: request timed out after 2500 ms

the message print by rtcpu is show below. I want to know “CHANSEL_NOMATCH” means what, and “data:0x00000549” means what. Thank you.

Hi,

From provided log it could be possible that the sensor output stream has a different resolution than expected. Does the image sensor is being configured correctly to output frames with a 1280x768 resolution?

What is the output of this command?

v4l2-ctl -d /dev/video0 --list-formats-ext

This issues are common too when embedded_metadata_height is not set correctly in the camera device tree. I recommend taking a look to this link: https://docs.nvidia.com/jetson/l4t/#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fcamera_sensor_prog.html%23

Hi,

The command “v4l2-ctl -d /dev/video0 --list-formats-ext” output like this:

~$ 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
Size: Discrete 1280x768
Interval: Discrete 0.025s (40.000 fps)

The information is the same with we expected.

And we set embedded_metadata_height = 0 now, we tried embedded_metadata_height = 1 and embedded_metadata_height = 2, the error is the same and we cannot get v4l2 image.

Hi, Our camera connect to xavier like this: sensor->ub953->ub960->xavier. The image to ub960 is 1280*768 and the format is raw10. Our dtsi is like this:

mode0 { // UB960_MODE_1280X768
mclk_khz = “25000”;
num_lanes = “4”;
tegra_sinterface = “serial_a”;
vc_id = “0”;
phy_mode = “DPHY”;
discontinuous_clk = “yes”;
dpcm_enable = “false”;
cil_settletime = “0”;
mode_type = “bayer”;
csi_pixel_bit_depth = “10”;
pixel_phase = “rggb”;

active_w = “1280”;
active_h = “768”;
readout_orientation = “0”;
line_length = “1600”;
inherent_gain = “1”;
mclk_multiplier = “12.8”;
pix_clk_hz = “320000000”;

min_gain_val = “1.0”;
max_gain_val = “177”;
gain_step_pitch = “0.1”;
min_hdr_ratio = “1”;
max_hdr_ratio = “1”;
min_framerate = “1.5”;
max_framerate = “60”;
min_exp_time = “16.165”;
max_exp_time = “165770”;
exp_time_1h = “8”;
embedded_metadata_height = “0”;
};
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
liub960_ub960_out0: endpoint {
vc-id = <0>;
port-index = <0>;
bus-width = <4>;
remote-endpoint = <&liub960_csi_in0>;
};
};
};

I think “embedded_metadata_height” means insert several lines in every frame image data, is it right?

We have already closed this function by setting sensor registers, and set embedded_metadata_height=0 in dtsi, but xavier report “NOMATCH”.

So could it be something else？

Where can I see the interpretation of this error number “0x549”?

Be sure to set “serdes_pix_clk_hz” to match the pixel rate of the CSI output of your deserializer and set pixl_clk_hz to the pixel clock of your image sensor.

“embedded_metadata_height” should be set to the number of embedded data lines that you sensor outputs. This may be zero. An embedded data line is a “line” that is not image data. There is a CSI line type field that denotes this. If what you enter in the device tree for this value does not match what Xavier see then you will have problems.

In your log I see CHANSEL_SHORT_FRAME errors which indicate that an end of frame (EOF) CSI packet was received but the Xavier saw fewer lines than “active_h”.

Thanks for your reply.

Now I find the NOMATCH event 0x549 indicate a line with data type = 0x2A received, but no VI channel is programmed to capture this data type. Our image data type is 0x2b(raw10), so we will go to find why the sensor send a line with data type=0x2a.

By the way, now we are using vc-id, one sensor connect to ub960 through one vc-id, and then connect to xavier.

One vc-id channel can only process one data type? If there is another type data we don’t know, the image data will be discarded?

Do you have any idea for this matter? Thank you.

Someone from Nvidia can provide a definitive answer but I believe that you are correct: only one data type is allowed for each VC-id. The one exception is embedded metadata lines.I believe the data type for this kind of line is 0x12.
