Porting driver from imx274 to imx334.
12bit rggb bayer, 3840X2160 30fps.
Save raw image successed by
v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat=RG12 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=ss.raw
But if run
gst-launch-1.0 nvarguscamerasrc ! fakesink
Desktop will hang then reboot.

Thanks for your help!!
Did you check the raw image?
v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat=RG12 --set-ctrl bypass_mode=0 --stream-mmap
The raw image data all zeros.
And the stream is continuous and maintain 30 fps.
Thank you!
Modify all of the control function like set_frame_rate() to dummy to try.
All control functions set to dummy already.
static struct tegracam_ctrl_ops imx334_ctrl_ops = {
.numctrls = ARRAY_SIZE(ctrl_cid_list),
.ctrl_cid_list = ctrl_cid_list,
.set_gain = imx334_set_gain,
.set_exposure = imx334_set_exposure,
.set_frame_rate = imx334_set_frame_rate,
.set_group_hold = imx334_set_group_hold,
// .fill_string_ctrl = imx334_fill_string_ctrl,
};
static int imx334_set_gain(struct tegracam_device *tc_dev, s64 val)
{
return 0;
}
static int imx334_set_exposure(struct tegracam_device *tc_dev, s64 val)
{
return 0;
}
static int imx334_set_frame_rate(struct tegracam_device *tc_dev, s64 val)
{
return 0;
}
static int imx334_set_group_hold(struct tegracam_device *tc_dev, bool val)
{
return 0;
}
Thank you!
Add 18ms delay after stream on , nothing changed.
@ShaneCCC ,How can I do for this situation?
Argus hang could be unable capture successfully from sensor and Nano didn’t implement recovery at some situation could cause OS hang.
We found a way let argus satisfy.
Change the resolution to 1920 1080 in dts , and with certain line length, “gst-launch arguscamerasrc ! fakesink” not going die now, Although sensor register setting to 3840 2160.
And I found this post https://forums.developer.nvidia.com/t/arducam-imx-219-not-giving-4k-video/201367/42
Is there some relations between the post and my problem?
I’m really appreciate for your help!
It could be the sensor REG configure problem due to 1080p working without problem.
@ShaneCCC ,
Below is new info:
3840x2180 , 4 lane , 12bit, 891M / lane , line length 4400, pixel clock 297000000, set all pixel data to 0x555.
capture raw data with:
v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat=RG12 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=10 --stream-to=ss.raw
In the raw file , first 3 frames all zero, then one frame all 0x555, then 3frames all zero, then one frame all 0x555.
When capture beginning, kernel log show:
We capture the data on oscilloscope, all four lane data is 0x555.
Argus still hang
Enable the debug print in csi2_fops.c to get the REG status.
sudo su
echo file ov5693.c +p > /sys/kernel/debug/dynamic_debug/control
sudo su
echo file csi2_fops.c +p > /sys/kernel/debug/dynamic_debug/control
kern.log
Jul 15 16:35:15 felix-imx kernel: [ 121.102096] vi 54080000.vi: Calibrate csi port 0
Log for break capture:
The REG dump all 0 that tell there’s no error, that could be CSI/VI didn’t receive any frame data from sensor.
In the raw file , first 3 frames all zero, then one frame all 0x555, then 3frames all zero, then one frame all 0x555.
CSI received few frames with correct data. But not for every frame.
Please check the kernel message to check if any TEGRA_CSI_* have none 0 value?
After few times v4l2-ctl capture stream, There are csi error in kernel log.

There have short error FIFO overflow and payload CRC error.
