Cannot capture from adv7280m with Jetpack-4.6.1

Dear Experts,

With Jetpack 4.5.1, I was able to capture analog video from adv7280m with the driver that I discussed in the following thread : ADV7280M Special Effect

Today, I pumped to Jetpack 4.6.1 and the driver of my adv7280m stays the same. However, I cannot capture the analog video from it anymore.

I applied the max. clocks for elements in the pipeline as below :

max-clock()
{
    local BASE="/sys/kernel/debug/bpmp/debug/clk"
    local name="$1"
    local clock_base="${BASE}/${name}"

    echo $(cat "${clock_base}/max_rate") > "${clock_base}/rate"
    echo 1 > "${clock_base}/mrq_rate_locked"
    
    echo -n "${name} clock rate is:"
    cat "${clock_base}/rate"
}


for clock in vi isp emc nvcsi; do
    max-clock "$clock"
done

which gave :

vi clock rate is:460800000
isp clock rate is:576000000
emc clock rate is:1866000000
nvcsi clock rate is:314000000

Then running following command :

gst-launch-1.0 v4l2src device=/dev/video1 ! xvimagesink

which resulted the following log :

I wonder what has been changed in the VI of new Jetpack that causes this capturing issue, please ?

Thanks in advance and best regards,
K.

Looks like output size didn’t as expect. Have a confirm the adv7280 output configure.

Hi @ShaneCCC,

Do you know if the output size of camera/bridge is shorter or longer than expected ? The driver together with the output mode of my adv7280m were working nicely in the previous Jetpack-32.5.1 however.

Best Regards,
K.

Dear @ShaneCCC ,

I did some tests by changing the power mode and there’s been some effect : at some power modes, I could not capture at all, at other power modes, first frame appears and freezes. Re-launching the gst-launch command could give some successful captures as well but not very stable (number of re-launching is random).

Meanwhile, I confirm that the driver works constantly stable with Jetpack 4.5.1.

Do you have any idea on this ?

Best regards,
K.

Hi @JerryChang ,

You sai from following discussion : ADV7280M Special Effect - #8 by JerryChang

could you please confirm this video content is interlaced.
currently, de-Interlacer is not supported on Xavier/r32.6.1 release.

Could you confirm that de-interlacer is still not supported on Xavier/r32.7.1 (Jetpack-4.6.1), please ?
What is strange is that I am able to capture with exactly the same driver on r32.6.1 (Jepack-4.5.1) and comparing the elements of NVCSI->VI pipelines in both BSPs does not show any significant update/change.

Best Regards,
K.

7

What do you mean different power mode?
Do you run nvpmodel -m 2 ? Could you also run the jetson_clocks to try

8

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

9

Hi @kayccc,

The issue is still there unfortunately. Sometime it can work after a certain retries of gst-launch but the number of retries until the successful capture is quite random. I might wait for next Jetpack release to test again as I don’t think there’s big change in the kernel BSP btw the working Jetpack-4.5.1 and the faulty BSP Jetpack-4.6.1 and my driver is exactly the same in the 2 versions.

Regards,
K.

Hi @ShaneCCC ,
nvpmodel -m 2 and jetson_clocks did not resolve my problem.

Rest regards,
K

11

Check it able output test pattern to verify.

12

Hi @ShaneCCC ,

Yes, it is able to output the test pattern (Color Bar), the only doubt is that I am not sure that it was a stream of test pattern or only some first images of the test pattern. However, it does show the test pattern right after launching the gstreamer command, while with images from real scene, first frames seem to be discarded and gstreamer shows nothing.

Best Regards,
Khang

13

If test pattern without problem that tell the adv7280 to NX without problem.

14

Hi @ShaneCCC ,

It seemed that only first frame(s) is/are captured. Running following command does not report any fps as it is blocking :

v4l2-ctl --device /dev/video1 --set-fmt-video=width=720,height=507,pixelformat=UYVY,field=interlaced --set-ctrl bypass_mode=0 --stream-mmap --stream-count=200

Best Regards,
K.

Test pattern?
Any different in the trace log?

16

Hi @ShaneCCC ,

Test pattern?
Yes.

Attached are the logs with test pattern enabled by following steps :
Root console :

vi clock rate is:460800000
isp clock rate is:576000000

The trace log tell the SPURIOUS data after the SOF. That could be the user define data cause the problem.
Have a check with vendor if able to disable the user define data package for trying.

Hi @ShaneCCC ,
Thanks for your suggestion. I will check the registers settings ( ADV7280M_ColorBar_480p.txtor ADV7280M_ColorBar_480i.txt) first. But, I am confused that I was working with previous jetpack release (r32.5.1) with same configuration, still.

On the same platform?

Maybe you can try modify the VI driver to ignore the err to try. Remove the goto uncorr_err;

static void vi5_capture_enqueue(struct tegra_channel *chan,
395  	struct tegra_channel_buffer *buf)
396  {
397  	int err = 0;
398  	unsigned int vi_port;
399  	unsigned long flags;

402  		.buffer_index = 0,
403  	}, {
404  		.buffer_index = 0,
405  	}};
406  
407  	for (vi_port = 0; vi_port < chan->valid_ports; vi_port++) {
408  		vi5_setup_surface(chan, buf, chan->capture_descr_index, vi_port);
409  		request[vi_port].buffer_index = chan->capture_descr_index;
410  
411  		err = vi_capture_request(chan->tegra_vi_channel[vi_port], &request[vi_port]);
412  
413  		if (err) {
414  			dev_err(vi->dev, "uncorr_err: request dispatch err %d\n", err);
415  			goto uncorr_err;
416  		}
417  
418  		spin_lock_irqsave(&chan->capture_state_lock, flags);
419  		if (chan->capture_state != CAPTURE_ERROR) {
420  			chan->capture_state = CAPTURE_GOOD;
421  			chan->capture_reqs_enqueued += 1;
422  		}
423  		spin_unlock_irqrestore(&chan->capture_state_lock, flags);
424  		buf->capture_descr_index[vi_port] = chan->capture_descr_index;
425  	}
426  	chan->capture_descr_index = ((chan->capture_descr_index + 1)
427  					% (chan->capture_queue_depth));
428  
429  	spin_lock(&chan->dequeue_lock);
430  	list_add_tail(&buf->queue, &chan->dequeue);
431  	spin_unlock(&chan->dequeue_lock);
432  
433  	wake_up_interruptible(&chan->dequeue_wait);
434  
435  	return;
436  
437  uncorr_err:
438  	spin_lock_irqsave(&chan->capture_state_lock, flags);
439  	chan->capture_state = CAPTURE_ERROR;
440  	spin_unlock_irqrestore(&chan->capture_state_lock, flags);
441  }

Yes, on the same custom board based on Jetson Xavier NX module (same module as well).

As per your suggestion, I modified the vi5_fops.c as below :

However, I was not able to stream still. And the error has always been :

not the one related to the modified code :
