We have a MIPI camera, but if the MIPI output only has one VC0, we can obtain images. However, if the MIPI outputs VC0 and VC1, we are unable to get images from VC0. Also, what are the methods to correctly obtain images from VC0 and VC1? Below is the log of the output for VC0 and VC1: root@ubuntu:…

hello DDEnginee, just an FYI, your sensor running with virtual channels (VC) that were used to carry separate streams simultaneously. this is not supported at the current Jetpack release version. please have a separate forum thread for tracking the issue with GMSL Protocol.

We refer to modifying DTS, but DMSG will report an error when checking the log [ 160.428452] ovx3c 9-0037: load ko version [2.3.0] [ 160.428465] ovx3c 9-0037: channel not found [ 160.428466] ovx3c 9-0037: ovx3c_probe: channel -97 [ 160.428469] ovx3c 9-0037: ovx3c_probe: sensor_index = 1 [ 160…

hello DDEnginee, are you using SerDes chips, which using Gigabit Multimedia Serial Link (GMSL) protocol? you should also add device tree property for gmsl-link{}.

We currently do not use serdes, only the sensor is connected to mipi 2lane, and the sensor will output two frames, vc0 and vc1. Currently, only outputting vc0 can produce images, but outputting vc0 and vc1 together cannot obtain images

hello DDEnginee, please refer to developer guide, VC it works with GMSL Protocol . [image] DDEnginee: the sensor is connected to mipi 2lane, and the sensor will output two frames, vc0 and vc1. this is not supported.

We have modified according to the GMSL format, but still cannot obtain the image without reporting any VC errors tegra234-p3767-camera-p3768-ovx3c-A-mulit-vc.dts.txt (20.4 KB) v4l2-ctl-2664 [007] ....... 871.576258: tegra_channel_open: vi-output, ovx3c 9-0037 v4l2-ctl-2664 …

[image] DDEnginee: The kernel also reported some errors: [ 3.166399] i2c i2c-2: Added multiplexed i2c bus 9 [ 3.166501] sysfs: cannot create duplicate filename '/devices/platform/bus@0/bus@0:cam_i2cmux/channel-0' [ 3.166518] CPU: 5 PID: 106 Comm: kworker/u16:1 Not tainted 5.15.148-tegr…

hello DDEnginee, may I know how’s the pattern looks like when the sensor output two frames, vc0 and vc1 to CSI channel.

At present, the sensor outputs images of vc0, which I can use video0 to obtain. However, when the sensor outputs images of vc0 and Vc1, I can only obtain the image of vc1 through video1, but the image of vc0 cannot be obtained by video0. This feeling is strange, as the image obtained by vc1 looks no…

hello DDEnginee, I meant.. how’s the streaming routing to CSI channel? how’s the VC0/VC1 coming to CSI? it’s by default to support camera stream continuously sending to CSI brick.

hello DDEnginee,

please refer to Jetson Virtual Channel with GMSL Camera Framework.
you may see-also reference driver which works with virtual channels.
i.e. hardware/nvidia/t23x/nv-public/overlay/tegra234-camera-ar0234-a00.dtsi
