Hey,
I’m writing a kernel driver for a MIPI sensor using the OV6693 sensor as a base, and have run into a bit of a dead end, from which I am not certain how to proceed.
The driver is being loaded, and is registered with the media-ctl device, however, when I try to capture from the video device, I get the following kernel messages. The last one is a print statement I have added to determine exactly where the timeout was occurring.
[ 326.187982] tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
[ 326.194437] tegra-vi4 15700000.vi: tegra_channel_error_recovery: attempting to reset the capture channel
[ 326.204684] tegra-vi4 15700000.vi: tegra_channel_capture_frame_single_thread++
As far as I have managed to discover, this indicates that the syncpt is not being incremented because the vi is not receiving a frame, however I’m not certain why not.
The only other thing that has raised any suspicion is that media-clt -p lists the sensor as the following.
type V4L2 subdev subtype Sensor flags 0
device node name /dev/v4l-subdev1
pad0: Source
[fmt:UYVY8_1X16/1920x1080 field:none colorspace:srgb]
-> "150c0000.nvcsi--1":0 [ENABLED]
The sensor itself is configured to be 1280x720 in the device tree, but I also need to configure it as UYVY8_2X8, which doesn’t seem to be an available option.
active_w = "1280";
active_h = "720";
mode_type = "yuv";
pixel_phase = "uyvy";
csi_pixel_bit_depth = "16";
Edit: I guess I would like to know if I am going about this the right way, or whether I should be using a different reference driver and device tree for a generic yuv sensor.
You may need to enable the trace log to get more information.https://elinux.org/Jetson_TX2/28.1_Camera_BringUp
Also you can reference to below topic fo UYVY8_2x8 from below topic.https://devtalk.nvidia.com/default/topic/1069374

Thanks Shane,
I now have the correct settings shown in media-ctl
- entity 4: gen_mipi 2-0066 (1 pad, 1 link)
type V4L2 subdev subtype Sensor flags 0

Had to remove all YUV_1X16 options from camera_common_color_fmts in camera_common.c and removed all yuv_xxxx16 options (and replaced them with yuv_xxxx8) from extract_pixel_format() in sensor_common.c.
However, I’m still getting the error messages when I use v4l2-ctl --stream-mmap
[ 911.267464] tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
[ 911.273992] tegra-vi4 15700000.vi: tegra_channel_error_recovery: attempting to reset the capture channel
[ 911.284297] nvcsi 150c0000.nvcsi: csi4_stream_check_status (2) ERROR_STATUS2VI_VC0 = 0x00000002
The kernel trace is attached, nope, it didn’t seem to upload. Added it following I power on the sensor after I start v4l2-ctl --stream-mmap, and it immediately begins sending data.

Shane, thanks very much. That put me onto looking at why there was a bit error, and it turned out I had some hardware related issues. I’m now getting video perfectly fine.
I have one last question.
The hardware nvidia directory contains two imx185 drivers, imx185.c and imx185_v1.c. Which one is the current accepted way of writing sensor drivers for the Tegra?
I can answer that question for Shane. The _v1 is the older approach. I have more experience with the older driver model but the new driver approach is easier and more flexible.
That’s right. Thanks D3_growe
