hello shenchengzha, [image] shenchengzha: The sensor is working, but the collection fails. it looks NULL VI channel received has reported, which represent there’s no frames coming to VI engine. may I know what did you meant “working”? for example, how you validate it’s functional?

During the collection process, when I tested the output clock using an oscilloscope, it was correct, and there were changes in the MIPI data lines as well. Should this confirm that the sensor is functioning? MIPI_CLK: [image] [image] MIPI DATA: [image]

hello shenchengzha, are you using customize carrier board? or, you’re tested with Orin NX developer kits? according to your device tree settings, you’ve two 4-lane camera sensor for using CSI-A and CSI-C. FYI, for the Orin NX DevKit, it’s Cam0 slot for using CSI-C, and Cam1 for using CSI-B. ther…

Hello JerryChang, currently I have made the changes to 2 lanes, port-index = <3>, tegra_sinterface = "serial_d", using CSI3, but I am still encountering the same error. [image] dts.txt (427.6 KB)

hello shenchengzha, could you please double check Jetson Orin NX Series and Orin Nano Series Design Guide for [Chapter 10. MIPI CSI Video Input] to review your pin connections. and… please revise your polarity setting to… lane_polarity = "0"; as it only CSI0 D1 and CSI1 D0 always been polarity sw…

Hello JerryChang, If we have currently selected a data rate of 1188Mbps, is it not necessary to configure the pix_clk_hz? [image]

please see-also Sensor Pixel Clock , you must be set pix_clk_hz correctly to avoid potential issues.

Hello JerryChang, The calculation process for pixel_clk_hz is as follows. Is the calculation method correct? [image] Sensor data rate = 891 Mbps (per lane) Number of lanes = 2 Bits per pixel = 10 Then pix_clk_hz = 891 Mbps × 2 / 10 = 178,200,000

hello shenchengzha, it looks correct, if you’re using sensor with data-rate larger than 1.5Gbps, please refer to Topic 268833 to apply rce-fw update.

@JerryChang can you quantify what the data-rate is you are talking about? I’ve looked through the documentation and it’s unclear what rate is being referred to in this conversation, and many others. This 1.5Gps. Is that PER lane, or ALL lanes added together. In the example about, it says 891 Mbp…

there shows PHY interrupt error, the error code 0x110 it means data-lane FIFO overflow.
please see-also similar topics for digging into data-lane FIFO overflow failures. such as… Topic 209574, and Topic 242054.
