Hi everyone,
I’m working on Xavier, JetPack 4.4, L4T R32.4.3.
When I test D-PHY signal by using different lanes(1/2/3/4), only Lane 2 is work on V4l2.
The Device Tree just change 2 parameter：num_lanes and bus-width
Here’s my device tree which is D-PHYx1Lane
mode0 { // OV5693_MODE_2592X1944
mclk_khz = "37125";//?
num_lanes = "1";//?
tegra_sinterface = "serial_e";//?
phy_mode = "DPHY";//?
discontinuous_clk = "no";//?
dpcm_enable = "false";//?
cil_settletime = "0";//?
active_w = "4928";//
active_h = "5000";//
mode_type = "bayer";
pixel_phase = "rggb";//?
//dynamic_pixel_bit_depth = "12";
csi_pixel_bit_depth = "12";//The sensor readout pixel pattern
readout_orientation = "0";//
line_length = "5000";//
inherent_gain = "1";//
mclk_multiplier = "2";//
pix_clk_hz = "74250000";//
gain_factor = "10";
min_gain_val = "0";//
max_gain_val = "720";//
step_gain_val = "3";
default_gain = "0";
min_hdr_ratio = "1";//
max_hdr_ratio = "1";//
framerate_factor = "1000000";
min_framerate = "2000000";//
max_framerate = "30000000";//
step_framerate = "1";
default_framerate = "30000000";
exposure_factor = "1000000";
min_exp_time = "30";//
max_exp_time = "660000";//
step_exp_time = "1";
default_exp_time = "33334";
embedded_metadata_height = "0";//?
};
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
e3326_ov5693_out0: endpoint {
port-index = <4>;
bus-width = <1>;
remote-endpoint = <&e3326_csi_in0>;
};
};
};
Also, I use gst command double check that.
And gst can work!
Below is dmesg
