v4l2 error:ctrl Gain range update failed

Robotics & Edge Computing Jetson & Embedded Systems Jetson TX2
1

Hello all,

I am using TX2 with Jetpack4.2-R32.1,Want to driver a pre-configured csi video without I2C.and I have done this before on Jetpack3.1, and it’s ok to grab the video stream:
https://devtalk.nvidia.com/default/topic/1025863/jetson-tx2/how-to-grab-pre-configured-csi-video-stream-without-i2c-/1

The input video stream is generated by a SDI-to-CSI2 adapter, it’s a 4-lane, 1920x1080@60, YUV422 signal. And I connected the input MIPI-CSI data and clk lines directly to the CSI port of tx2.

We use the ov5693.c as template to implement the sensor driver.

But when I modify the kernel source code on R32.1, The error has occurred:
[ 4.374937] OV5693_sdi1 2-0036: ctrl Gain range update failed
[ 4.374942] OV5693_sdi1 2-0036: Error -34 updating mode specific control ranges
[ 4.374945] OV5693_sdi1 2-0036: Error -34 updating control ranges
[ 4.374964] OV5693_sdi1 2-0036: Failed to init ctrls ov5693
[ 4.374967] OV5693_sdi1 2-0036: tegra camera subdev registration failed

I found the code between the r28.1 and r32.1 is very different.

How to fix this error?

Hello,I really need some help…

hello suchb,

we had update linux kernel version to kernel-4.9 for JetPack-4.x
suggest you refer to [Sensor Driver Programming Guide]-> Camera Sensor Drivers Porting Guide for porting your sensor driver.
thanks

@JerryChang, Many thanks

According to your suggestion I modify the device tree and ov5693.c,looks csi sensor driver being probed successfully.

But I have missing /dev/video0 and there is no error in dmesg log.

err = of_property_read_string(client->dev.of_node, “devnode”, &devnode);

I got the right devnode “video0” and ov5693_debugfs_create is success:

#root@nvidia-desktop:/sys/kernel/debug/camera-video0# ls
#streaming

My modifications are based on R32.1 original source code and original dtsi, I think this ov5693.c is compatible with kernel 4.9.

What are we missing?

hello suchb,

you need to have kernel drive update to extend YUV format support,
please check the attachment of the r32.1 patch to add YUV format for VI drivers.
thanks

hello suchb,

you should disable plugin manager if your camera board don’t have EEPROM.
please also refer to [Sensor Driver Programming Guide]-> Using Plugin Manager session.
thanks

Thanks JerryChang,

I have already disable plugin manager dtsi in tegra186-quill-p3310-1000-a00-00-base.dts

hello suchb,

all these dtsi files combine and build into signal dtb file for Jetson platform.
suggest you have an alternative way to check if all your configuration included in the final dtb file.
here’s commands to disassembler the dtb file into txt file for your quick checking.
thanks

$ dtc -I dtb -O dts -o temp.txt tegra186-quill-p3310-1000-c03-00-base.dtb

hello suchb,

please check your control range settings of below CID controls,
you may also add some debug message to check which control caused the failure.
TEGRA_CAMERA_CID_GAIN
TEGRA_CAMERA_CID_FRAME_RATE
TEGRA_CAMERA_CID_EXPOSURE
TEGRA_CAMERA_CID_EXPOSURE_SHORT

please note that there are two V4L2 Kernel Driver versions if you’re working with JetPack-4.2
please refer to Sensor Driver Programming Guide, and check the [V4L2 Kernel Driver (Version 2.0)] for details.
thanks

Hi JerryChang,

struct camera_common_data *s_data = tc_dev->s_data;
struct sensor_control_properties *ctrlprops = NULL;
int i;

if (modeidx >= s_data->sensor_props.num_modes)
	return -EINVAL;

…

error occurred in here when update control ranges based on mode settings,modeidx >= s_data->sensor_props.num_modes

14

hello suchb,

this error means no sensor modes available, could you please check your kernel driver header.
you should follow the camera_common_frmfmt structure and report your sensor modes.
please also refer to below for an example,

$TOP/kernel_src/public_sources/kernel/nvidia/drivers/media/i2c/imx185_mode_tbls.h

static const struct camera_common_frmfmt imx185_frmfmt[] = {
...
};
15

yes JerryChang,

I’m working on this.

I found some other Frame Size can be set successful but 1080P is not ok.

Thank you.

Hello JerryChang,

I have merge the Topic1050578_Apr24_patch.tar.gz patch, and made the vo5693_frmfmt only have one frameformat OV5693_MODE_1920X1080.

But when i use qv4l2 to grab video stream, the Capture Image Formats can’t be set to YU12 or YUV422,it always be BG10 as default, and dmesg is no error line.

when run :v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test.raw

I got bellow info:

hello suchb,

  1. since you refer to bayer sensor device tree and have modification to yours.
    had you also update sensor device tree to report pixel format as YUV format.
    for example,
mode0 {
                                ...
                                active_w = "1920";
                                active_h = "1080";
                                ...
                                pixel_t = "yuv_yuyv16"

suggest you check below kernel sources for complete pixel format types.

$TOP/kernel_src/kernel/nvidia/drivers/media/platform/tegra/camera/sensor_common.c

static int extract_pixel_format(const char *pixel_t, u32 *format)
{...}
  1. also, please given complete options to v4l2 standard controls.
    for example,
$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=UYVY --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1
  1. your error message might be related to not complete hardware signaling.
[ 1899.539226] tegra-vi4 15700000.vi: PXL_SOF syncpt timeout! err = -11
  1. if you still meet failure by correcting sensor device tree and using complete commands to access the camera sensor.
    could you please enable VI tracing logs as below to gather more details.
