CSI Camera Issue in L4T 35.1

chaithra.bv · April 4, 2023, 1:33pm

Hi,

I am Trying to enbale 3rd-CSI Camera in L4T 35.1, and Modified the device-tree configurations for that .Its a 2-Lane CSI Camera and
reffered the link to add port-index :- Tegra Linux Driver

In dmesg getting the following error,

jetson@jetson-desktop:~$ sudo dmesg | grep “imx219”
[sudo] password for jetson:
[ 11.564068] imx219 0-0010: Failed to find port info.

Please, help me out to resolve the above issue @ShaneCCC @WayneWWW

Thanks

hello chaithra.bv,

your port bindings looks incorrect.
you should use CSI-G, and it’s connected to VI-5.
it means… the port index should be port-index=6 for nvcsi, whereas tegra-capture-vi using port-index=5.

BTW,
could you please moving to latest release, which also include bug fixes for camera functions.

chaithra.bv · April 6, 2023, 10:13am

hello @JerryChang,

Thanks for the update, I have tried the port-Index = 6 for nvcsi and checked the status of CSI Camera in “ls /dev/video”,(device nodes) Now its Camera- 3 is detecting and blank screen is appearing while previewing the Camera and the system is hanging at this stage and rebooting automatically.

How I can resolve this?

JerryChang · April 7, 2023, 2:50am

hello chaithra.bv,

may I know the kernel logs while the camera stream enabled?
so, you meant you cannot terminate the pipeline to recover that until watchdog timeout to reboot the system?

chaithra.bv · April 7, 2023, 5:45am

hello @JerryChang

I have mentioned the dmesg logs below:-

jetson@jetson-desktop:~$ dmesg | grep “imx219”

[ 11.700718] imx219 0-0010: tegracam sensor driver:imx219_v2.0.6
[ 11.722279] tegra-camrtc-capture-vi tegra-capture-vi: subdev imx219 0-0010 bound

JerryChang · April 7, 2023, 6:05am

hello chaithra.bv,

that’s kernel init messages to probe the camera device.
what’s the actual failure of blank screen?

chaithra.bv · April 7, 2023, 6:28am

hello @JerryChang

The Actual failure for blank screen is :-

jetson@jetson-desktop:~$ journalctl -o short-precise -k -b -1

Apr 21 18:24:39.866820 jetson-desktop kernel: tegra-camrtc-capture-vi tegra-capture-vi: Invalid NVCSI stream Id

JerryChang · April 7, 2023, 6:48am

hello chaithra.bv,

it’s reported an invalid NVCSI stream ID, hence the stream is not initialized.
please double check your device tree settings, especially the port bindings.

chaithra.bv · April 9, 2023, 6:01pm

hello @JerryChang

I have Checked the device tree and the same device tree is using for L4T 32.6 also, their, its working fine without any issues.

But, in the 35.1, I am facing this issue, is their any unique changes in the L4T 35.1 related to IMX219 CSI Camera?

JerryChang · April 10, 2023, 2:42am

hello chaithra.bv,

may I know how your migrate the driver from r32.6 to r35.1?
you may see-also reference driver for comparison,
for example, $public_sources/r35.1/Linux_for_Tegra/source/public/hardware/nvidia/platform/t19x/jakku/kernel-dts/common/tegra194-camera-rbpcv2-imx219.dtsi

may I know how many cameras on your camera board?
do you have all of three cameras well connected, or, it’s only single camera connected for 3rd-CSI verification?
please also share your revised device tree for review again, thanks

chaithra.bv · April 10, 2023, 11:18am

hello chaithra.bv,

here’s incorrect port bindings for VI stream.

please also check Port Index session for reference.
since there’re only 5 VI steams available, you should define the camera using CSI-G as following.
i.e. sensor → CSI-G (port-index=6) → VI stream (port-index=5).

chaithra.bv · April 13, 2023, 6:50am

Thankyou for your support @JerryChang,

CSI Camera-3 is Working fine.
