Some problem about my imx219 driver on TX2 R28.1

[haijun]

(1)Now,I’am developping the driver for imx219 on TX2 R28.1.We use J20 borad bought from Auvidea.Through the v4l2 command,I can get a raw image.The v4l2 commond is as follows:
v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --stream-mmap --stream-count=1 --stream-to=imx219.raw
But in the dmesg log it outputs some error:
[ 1568.375630] arm-smmu 12000000.iommu: Unhandled context fault: iova=0x00000000, fsynr=0x100011, cb=19, sid=4(0x4 - VI), pgd=0, pud=0, pmd=0, pte=0

b I use nvgstcapture command,it outputs like this in the terminal:[/b]

bitrate = 4000000
Encoder Profile = Baseline
Socket read error. Camera Daemon stopped functioning…
gst_nvcamera_open() failed ret=0

** (nvgstcapture:2379): CRITICAL **: main:5367 Capture Pipeline creation failed

I check the dmesg about nvgstcapture,the log is as follows:

(3) I took a picture of the output raw image and attached it,and attached the dts file and driver.

I updated the problem information.I find some people meet the same problem.Please Nvidia’s enginers help us to solve it.We’re so eager to finish the camera driver on TX2.

[haijun]

I need help.Anyone could help me?Where is Nvidia’s enginers???

@haijun
For the imx219 data sheet this sensor have output embedded data, did you try to set the embedded_metadata_height = “1” to try?

[haijun]

@ShaneCCC
Thank you for your reply!I have tried that way.I set the embedded_metadata_height = “1”.However it still outputs error information.

[haijun]

Other peopep have the same problem.They could not solve it either.

[haijun]

Ridgerun is developping the driver for imx219 on TX2 R28.1.They meet some obstacle on it.They said “TX2 driver actually have some limitations”.I’m so confused about that.I need your help,ShaneCCC.Thank you so much!

[ShaneCCC]

1. Below log show be gone when you set the embedded_metadata_height = “1”,

2. Could you try to tune this define DEFAULT_THS_SETTLE it’s range is 1 - 0x3f
   csi4_registers.h

[ 1568.375630] arm-smmu 12000000.iommu: Unhandled context fault: iova=0x00000000, fsynr=0x100011, cb=19, sid=4(0x4 - VI), pgd=0, pud=0, pmd=0, pte=0

[haijun]

I tried to tune the define DEFAULT_THS_SETTLE,but it is not useful!

[haijun]

When I run command “v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --stream-mmap --stream-count=1 --stream-to=imx219.raw”,the dispaly monitor would be flashing.I attach the video of my command!

[ShaneCCC]

Could you confirm the value of embedded data lines from vendor? Or try few number.
