V4l2-ctl cannot receive the sensor frame

[talagimi63]

I am facing a problem when I try to get the frame from the camera sensor. I want to get the frame in two or three ways. First, using a V4L2 based program. The bottom part of the image has a problem and I have also included the log file.

In the second method, I got the image using ISP, the bottom part of the image has a skull and I have also included the log file.

I am using camera sensor driver IMX462. and in all pixel mode (1080p 60 fps):

num_lanes = "2";
tegra_sinterface = "serial_a";
lane_polarity = "6";
active_w = "1920";
active_h = "1088";
csi_pixel_bit_depth = "10";
line_length = "2640";
mclk_multiplier = "2.4";
pix_clk_hz = "178200000";

What is the problem that I am not getting the correct image?

hello talagimi63,

it looks something wrong with the output stream, there’s no CHANSEL_PXL_EOF per your tracing logs.
ideally, here must be one pair of CHANSEL_PXL_SOF/CHANSEL_PXL_EOF to indicate a frame has detected by VI engine.

besides.. may I know what’s the sensor output format types?
there’s nomatch failure reported, it looks NvCsiDataType NVCSI datatypes mismatch.
CHANSEL_NOMATCH channel:0x01 frame:170 vi_tstamp:1703834152224 data:0x00000000000006e9

sensor output format type is RAW10

I set the “active_w=1948” and the image result was good but I don’t understand why I should choose the number 1948 when I expected the number to be 1920.

you may dig into sensor spec for checking the active dimension, and also examine the sensor reg init table for confirmation.
