Hi, I am working on Jetson AGX Orin to debug a camera issue. The test is performed in Jetson AGX Orin Kit. The error message “tegra-camrtc-capture-vi tegra-capture-vi: corr_err: discarding frame 4430, flags: 0, err_data 131072” is reported. More information:

  • Jetpack version is R36.4.0.
  • Video data format is YUV422
  • Frame rate is set to 4fps
  • Resolution: 3840x2160

Could you please help to check the kernel log below? What may cause the issue?

The debug log is attached.

From the log, I assume Frame Start is reviewed. But error happens before capturing the Frame End.
The device tree is verified by another camera module. So I suspect something wrong with the MIPI signal.
The waveform on one MIPI data lane looks good.
What else shall I check?
Thanks!

hello ygao6,

why the frame count is jumping, may I know what’s your capture pipeline?
please see-also Topic 318537 for some details of discarding frame reports.

Thanks for your answer! I can understand the definition of the error data. It is helpful to investigate the issue.
Now the issue is fixed after we lower down the DPHY clock. The clock was set to 2.5GHz when the issue happens.
