Kernel crash when capture mipi csi video

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX
#1

Hello forum,

I am using 16G-EMMC NX with Jetpack4.4 to capture a pre-configured csi video,1920x1080@30fps UYVY, 4lane, connect to our carrier board CSI port0 and port1.
nv_tegra_release:# R32 (release), REVISION: 4.3, GCID: 21589087, BOARD: t186ref, EABI: aarch64, DATE: Fri Jun 26 04:34:27 UTC 2020

I got kernel crash when capture video0 raw data:

v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.raw --set-fmt-video=width=1920,height=1080,pixelformat=UYVY

kernel log:
crash.log (37.4 KB)

Can anybody tell me what is going wrong here…
Thanks so much.

Hello, I need help.

Thanks.

Are you able to get the trace log.

The trace log show didn’t receive any data from the MIPI bus,
Could you don’t program the sensor streaming on to check if the kernel crash cause by NVCSI/VI didn’t receive data or the sensor driver cause it.

#8

Hi， ShaneCCC，
If I turn off the mipi output then v4l2-ctl will not cause kernel crash.

#9

OK, from the trace NVCSI/VI didn’t receive any validate data from the MIPI bus.
I think you may need to probe the MIPI signal to make sure the sensor output data as MIPI spec.

#10

Hi,ShaneCCC
Could you please help me check my dts code?

The MIPI signal works fine on TX2，the mipi output without cam_i2c,I changed ov5693 driver code and dts to capture the video.And on NX I test with IMX219.

Is there any different between tx2 and nx nvcsi/vi driver code？

Not sure if below cause the problem.

pixel_t Deprecated. Use the following properties instead:

•mode_type

•csi_pixel_bit_depth

•pixel_phase

#12

Hi ShaneCCC，

I have already add the 3 properties and get same error:
mode_type = “yuv”;
pixel_phase = “uyvy”;
csi_pixel_bit_depth = “16”;

#13

Maybe you may need to check if the sensor is connect to the right lanes due to didn’t receive any validate data.

#14

Hello, ShaneCCC

V4l2-ctl cmd will not cause kernel crash now,I get new trace log as below:
trace.log (33.8 KB)
Please have a look.

Thanks

#15

It could be HW or signal issue.
Have a check the TRM the REG NVCSI_PHY_0_CILA_INTR_0_STATUS_CILA_0
