Hi,

I develope a camera that its resolution can be 1280x1080,2560x1080,3840x1080 and 5120x1080(pixel format is yuv422 8 bit,isp bypass mode).It can successfully capture when resolution less than 5120x1080.
When I try 5120x1080,the tegra-vi error occurred.Follow is the log

It seems tegra-vi cannot support so big resolution.
Is there a solution to solve this problem? Thank you a lot!

hello CalmCar,

may I have more details about your environment,
for example,

  1. which JetPack release you’re working with
  2. what’s the frame rate of your 5120x1080 sensor mode.
  3. may I know whats’ the pixel clock you had configured for your sensor.

Hi JerryChang

1.I’m working on JetPack 4.2
2.Frame rate is 25fps
3.The pixel clock is 96MHz

Thank you

hello CalmCar,

could you please have a quick try to lower the frame rate to check if there’s bandwidth issue.
thanks

Hi JerryChang

I will have a try.
Is there any documents about the bandwidth,resolution and so on of Jetson AGX xavier?

hello CalmCar,

you might check the Jetson AGX Xavier Software Features for validate use-cases.
for more details, please also access [Xavier Series (SoC) Technical Reference Manual] from Jetson Download Center,
please refer to [Multimedia Complex]-> [Camera Subsystem]-> [Image Data Types],
and check the [Performance] session for the NVCSI maximum bandwidth.

BTW, we had also validate CPHY sensor with 5488x4112 at 30-fps.
