recentlly we have a driver tc358743 requirement
I have following the doc about https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3271/#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/camera_sensor_prog.48.1.html#

and implement the v4l2 driver v1

I have successfully get the /dev/video0 and check the hdmi input are succesfully capture

mmc@ubuntu:~$ sudo v4l2-ctl --log-status -d /dev/video0

I have read the document that v4l2 have two version driver . and v1 is no support right now ?
and I try to porting the driver to v2 version but more problem show .

the doc say
V4L2 Control Ops

V4L2 control ops communicate with the V4L2 framework. These operations are handled automatically in the Jetson V4L2 Camera Framework, and need not be added to individual sensor driver:

•v4l2_ctrl_ops

•v4l2_subdev_ops

•v4l2_subdev_video_ops

•v4l2_subdev_core_ops

•v4l2_subdev_pad_ops

for one example how can I implement the log_status ops function now ?

any help would be appreciate

hello mmcuav_dev,

you may see-also developer guide for understanding V4L2 Kernel Driver (Version 1.0) and V4L2 Kernel Driver (Version 2.0).
actually, as you can see in the reference driver, both 1.0 and 2.0 were supported.

you may review your DT sources for such NULL pointer failure.
BTW, may I also know which JetPack release you’re working with?

Hi JerryChang,

very appreciate for your quick response .

I use jetpack 4.6.2 which L4T is R32.7.2

may I kown more about how can I determine the kernel NULL pointer dereference at virtual address 000000a0 is cause by DT sources ?

thanks.

5

please trace tegra_vi5_g_volatile_ctrl for which entry is loaded to cause NULL pointer.

6

sure . thanks again

Hi @JerryChang

thank you for your kind help.

now I have fixed crash when calling tegra_vi5_g_volatile_ctrl

and I can success call

    };

which csi port and vi port index are 4 ,means CSI E F and also clock-lanes = <4> which meas CLOCK E

I am not sure if it is right for that configuration .

Thanks again.

hello mmcuav_dev,

that device tree connections looks correct.
could you please have v4l2 standard controls to access the stream.
for example,
$ v4l2-ctl -d /dev/video0 --set-fmt-video=width=1280,height=720,pixelformat=UYVY --stream-mmap --stream-count=100

and…
please also follow below steps to enable VI tracing logs.
for example,

echo 1 > /sys/kernel/debug/tracing/tracing_on
echo 30720 > /sys/kernel/debug/tracing/buffer_size_kb
echo 1 > /sys/kernel/debug/tracing/events/tegra_rtcpu/enable
echo 1 > /sys/kernel/debug/tracing/events/freertos/enable
echo 2 > /sys/kernel/debug/camrtc/log-level
echo > /sys/kernel/debug/tracing/trace
cat /sys/kernel/debug/tracing/trace
# or, to review dynamic tracing log
# cat /sys/kernel/debug/tracing/trace_pipe

Hi JerryChang,

I have follow the command as you mention

v4l2-ctl -d /dev/video0 --log-status

It seems I can no get any useful information from the output .

hello mmcuav_dev,

it looks like VI engine side did not receive any validate signaling.
you should at least have start-of-frame and end-of-frame coming to CSI brick.

is it possible to enable test-pattern-generator of this tc358743 bridge driver?
this may helps to narrow down the issue.

11

I am no sure what test-pattern-generator is something like ? maybe it is something like make tc358743 to continue generate csi signal without v4l2 to command it to start transmmit . Whatever now with your help I can sure that the device tree configure is right , the problem can be narrow to csi transmite part .

then I can check the csi output signal or something else method .

thank you for your kindly help.

hello mmcuav_dev,

test-pattern-generator is one functionality on that bridge chip, it’s able to send color bars to CSI brick by itself.
please check CSI output signal, VI engine should see frames if there’s high speed signaling.

for debugging.
you may also follow below commands to boost all the VI/CSI/ISP clocks to eliminate clock config related issues.
for example,

sudo su
echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate |tee /sys/kernel/debug/bpmp/debug/clk/vi/rate
cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/isp/rate
cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
cat /sys/kernel/debug/bpmp/debug/clk/emc/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/emc/rate

Hi @JerryChang ，

A long time try . I have’t get the video yet . Here I have some question about nvcsi/vi port link .

Because my hardware use CSI E F and CSI E clock .

In my device tree I assign with


  
         vi@15c10000  {
            num-channels = <1>;
            ports {
                #address-cells = <1>;
                #size-cells = <0>;
                tc358743_vi_port2: port@0 {
                    status = "okay";

                    };
                };

        };
    };
};
};

  i2c@3180000 {  /* I2C_0, "adapter" 0 */
        status = "okay";
        #address-cells = <1>;

        tc358743@0f {

                };
            };
        };
    };

but I have find any csi-port or clock-lanes when tegra194-camera-imx185_v1-a00.dtsi

and it has

	mode4 {/*mode IMX185_MODE_1920X1080_CROP_HDR_30FPS*/
					mclk_khz = "37125";
					num_lanes = "4";
					tegra_sinterface = "serial_a";
					phy_mode = "DPHY";
					discontinuous_clk = "no";

tegra_sinterface and phy_mode defination whihc I am no assign in tc358743 . is it correct ?

here is my complete device tree file

hello mmcuav_dev,

below settings are unnecessary since you’re using bridge driver.

you should configure device tree correctly for setting up TC358743 -> NVCSI -> VI port bindings.
you may see-also developer guide for To verify the port binding result to review the device topology.

according those VI tracing logs.
it seems there’re valid timestamps on the CSI channel, however, it doesn’t contain start-of-frame, and end-of-frame which indicate a capture frame.

@JerryChang Hi

after a long time try . I successfully get the 1080p60 stream .

Here are my code repo GitHub - askariz/tc358743_nx_driver if are help to some other guy

and still I have some problem about the driver .

like h2c it is intterupt only work at the startup stage . but nerver happend again


mmc@ubuntu:~$ sudo cat /proc/interrupts
[sudo] password for mmc:
           CPU0       CPU1       CPU2       CPU3       CPU4       CPU5
388:          4          0          0          0          0          0  tegra-gpio 196 Edge      tc358743

and also when I try with 720p It seems no work with a full greeen screen

the delay of h2c is aroud 174ms . is it normal

and also if there can be more detail meterial about the whole pipeline about nvcsi and vi like how the rtos mcu work , how to debug it ? how the log is meanning

best regards .

hello mmcuav_dev,

since there’s some progress. suggest we mark this as solved and initial another new thread to follow-up your 720p issue.
you may also attach the latest kernel failures and also VI tracing logs.
thanks
