Camera FPS Setting based on FS, FE

Hello,

I have a question about Camera Sensor Porting.

We are currently developing sensor drivers for Depth camera.

However, our sensor is 20FPS, but we need to receive about 50 slots to receive 1FPS.
The problem is that when i look at the data format, the data(1 slot) has three embedded data lines and 24 data lines between the FS and FE, and real one frame can be configured with 50 slots.

Therefore, I have configured device-tree with embedded data line = 3, active_h = 24, framerate = 1000 (50 slot* 20fps) based on FS and FE, but when capturing raw data with v4l2, there seems to be an error in operation.

mode0 {
				mclk_khz = "24000"; 
				num_lanes = "4"; 
				tegra_sinterface = "serial_a";
				phy_mode = "DPHY";
				discontinuous_clk = "no";
				dpcm_enable = "false";
				cil_settletime = "0";
				csi_pixel_bit_depth = "12";
				dynamic_pixel_bit_depth = "12";
				mode_type = "bayer";
				pixel_phase = "rggb";

				active_w = "1564";
				active_h = "24";
				readout_orientation = "0";
				line_length = "1564";
				inherent_gain = "1";
				/*mclk_multiplier = "12.5";*/
				/*pix_clk_hz = "300000000";*/
				pix_clk_hz = "300000000"; /* 800M 4lane 12bit */
				gain_factor = "10";
				min_gain_val = "0"; /* 0dB */
				max_gain_val = "480"; /* 48dB */
				step_gain_val = "3"; /* 0.3 */
				default_gain = "0";
				framerate_factor = "1000000";
				min_framerate = "1500000"; /* 1.5 */
				max_framerate = "1200000000"; /* 1200 */
				step_framerate = "1";
				default_framerate= "1000000000";
				exposure_factor = "1000000";
				min_exp_time = "0"; 
				max_exp_time = "66000";
				step_exp_time = "1";
				default_exp_time = "892";
				embedded_metadata_height = "3";
			};

If so, I wonder if it’s okay to set active_h = 1450( 29 (embedded 3+ data 24+ FS+ FE) * 50 (slot)) to one frame with frame rate = 20.

If I increase the active_h and frame resolution, can I ignore FS and FE and receive continuous data as one?

Any help would be greatly appreciated.
Thanks.

Suppose should be able to support it.

Hello,

I modified active_h and framerate according to your advice.
I also confirmed that the state of sensor is ACTIVE using I2C. However, the sensors and logs are displayed in the same state.
The sensor is producing output, but the VI doesn’t seem to be receiving any data. Any advice would be appreciated.

Those errors show something wrong from PHY
From software side, please confirm that the lane configuration is correct, and sensor is configured correctly. Wrong configurations may also result in such error.
If settings are good, most probably, the signal is corrupted.

Hello Shane,

Thank you for your advice.
I checked our lane settings, but nothing looks special.
However, we are using 4 lane and the circuit is configured as follows.

Is it correct that the error message in the log indicates the problem in all of 4 lanes?
Or I’m wondering if there’s a wrong configuration on circuit or if there’s anything I need to mention in the SW about the line order.

I have attached the dtsi file.

tegra194-camera-imx999-a00.dtsi (9.2 KB)

we are also Modifying the interface board for MIPI signal verification.
Are there any other files I need to check for lane configuration?

Thanks.

The port configure is correct.
Please also confirm the sensor output by 4 lanes configure.

Thank you for your answer.

Could you tell me the meaning of the status value of log?
I wonder if the log simply means CTRL+C interrupt, or if it’s a signal error you mentioned.

Thanks.
