Camera error: uncorr_err: request timed out after 2500 ms

[shenchengzha]

Platform: Orin NX
SDK: 35.4.1
When running the command to capture images, an error occurred. How can I resolve this?

v4l2-ctl -d /dev/video0 --verbose --set-fmt-video=width=1920，height=1080，pixelformat=UYVY --set-ctrl=sensor_mode=0 --stream-mmap --stream-count=100

[shenchengzha]

Is there a problem with the DTS configuration I have set? Could you please help me take a look? I have been unable to resolve this issue, and I’m not sure what the cause is.

[ShaneCCC]

CAM0 only support 2 lanes configuration and need set the port-index =1
and tegra_sinterface = “serial_b”

@shenchengzha

						rbpcv2_imx568_csi_in0: endpoint@0 {
							port-index = <0>;
							bus-width = <4>;
							remote-endpoint = <&rbpcv2_imx568_out0>;

[shenchengzha]

I have made the modifications according to your suggestions, but the error remains the same and I’m not sure what the problem is. What should I do next to fix it?

[ShaneCCC]

CAM0 only support 2 lanes configure. Need modify the sensor output as 2 lanes mode too.

@shenchengzha

bus-width = <4>

[shenchengzha]

How can I make changes to support 4 lanes if I want to?

[ShaneCCC]

Due to HW CAM0 can’t support 2 lanes. You can design customized sensor board to use other CSI port instead of CSI0-1

Please check the sensor design guide from downloader center.

[shenchengzha]

Does the hardware need to be modified to support 4 lanes for CAM0?

[shenchengzha]

I changed it to CAM1, but I still couldn’t get any image output.

[ShaneCCC]

Did you connect the camera to devkit? or customized sensor board?
Devkit only support 2 lanes by HW connection.

[shenchengzha]

This is the interface diagram of my board, which is the same as the Jetson Orin Nano Developer Kit baseboard interface.

[ShaneCCC]

OK, the trace log show didn’t receive any validate data from sensor.
Maybe need to probe the signal to confirm.

[shenchengzha]

When capturing images, the test data line and clock undergo changes, and the output clock frequency is equal to the frame rate. However, images still cannot be captured. What could be the reason for this?

CSI2_CLK_P/CSI2_CLK_N:

lanes data:

[ShaneCCC]

Could you dump the device tree to confirm the config.

sudo dtc -I fs -O dts -o extracted_proc.dts /proc/device-tree

[shenchengzha]

dumped device tree, Could you please help me confirm if there is any issue with the device tree?

sudo busybox devmem The output values are all 0xFFFFFFFF. Does this have any impact?

Looks like the firewall doesn’t disable.
Check the kernel message if panic message to confirm.

How should this be handled?
