Hey. I got the image to boot. Now, please review this photo. I had this complication while building in the past and never received confirmation of a valid answer.

I know nothing about my HDMI 5” screen/display. Now, here is the photo:

Excuse the mess, please. My HDMI Display is giving me the willies.

Please send some type of guidance.

How can I set the display resolution on the BeagleY-AI for an HDMI LCD? I want to try to see if I can get one of the models working that the person put together for this image…

xrandr?

Maybe another example would come in handy…

Here is what the camera is capable of now. Would I need to set the size of the feedback to a particular resolution?

Also, does this application(s) do other things besides what is listed on the docs. pages?

Update

  1. I am trying to cancel out errors
  2. I am trying to see what works
  3. See below for what I have tried from the docs. pages

gst-launch-1.0 -vvv v4l2src device=/dev/video-usb-cam0 io-mode=5 ! video/x-raw, width=800, height=480, format=YUY2 ! autovideosink is the command I used to try to get the USB CAM to show its face on the HDMI LCD.

With the above command, I get this error:

streaming stopped, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.

and when I change the width, height, and format commands to what I believe my USB CAM understands, I receive this error:

WARNING: erroneous pipeline: could not link 
v4l2src0 to autovideosink0, v4l2src0 
can't handle caps video/x-raw, width=(int)800, height=(int)480, format=(string)YUYV

As you can tell, the USB CAM does not like the commands or is it the image and what is available?

I will run dmesg and try to find out.

One issue. The LCD is off-center. I have tried to go into grub.cfg and add particular commands to handle the HDMI display.

I will try this command next and then the update-grub command as well: GRUB_GFXMODE=640x480.

Thank you for reading. If you have any ideas, please let me know.

to test out the display, why not try the test patterns?

work on issue at a time.

# Display default test pattern (SMPTE color bars)
gst-launch-1.0 videotestsrc ! autovideosink

# Display a specific pattern (e.g., ball, snow, smpte)
gst-launch-1.0 videotestsrc pattern=ball ! autovideosink

# Display a 5-second video of a test pattern then exit
gst-launch-1.0 videotestsrc num-buffers=150 ! autovideosink

Okay. I will test it. The rule of thumb is to stop the process running and then go for the test patterns.

So, I would need to halt the running GUI and then test.

Hmm. It seems I am out of room? actual-sink-kms: drmModeSetPlane failed: No space left on device (28)

I checked df -h and it returned that I have 20GB of memory leftover after the initial install of the image…

Should I check elsewhere? Also, another thing I noticed: Image-6.12.17-ti-00773-gcdcaeac783e3-dirty. Dirty…

Some stuff I tried so far:

  • changing the framebuffer set up in:
    • grub.cfg
    • on the command line
  • Some commands I have tried:
    • fbset
    • dmesg | grep hdmi

Send guidance on this effort. I cannot get past the initial part due to the set up of my HDMI LCD at 1024 * 768.

Update

So, I changed to a larger HDMI LCD. fbset is of no use so far. Most of the screen is present but I cannot start the scripts even on the main screen…

  • with USB1 and/or USB0 from the USB camera
  • even after killall edgeai-gui-app
    • and then with a command as in gst-launch-1.0 videotestsrc ! autovideosink

E for effort so far…

If anyone has any documentation this effort (E), please let me know. Once I start the usb cam on the main screen of the HDMI LCD, I get the error on graphics only, e.g. commands via mouse shutdown the edgeai-gui-app.

Another Update

  1. I got one of the camera modules to run from the main LCD with a couple of points and clicks.
    1. Video on the way…
  2. Outside of that module running, I need to figure out whatever else can be done with this image…
    1. I see there was some GPIO and PWM controller peripherals set up with a TI set of applications/libraries.

If you are lucky, you can see my bald head in the timelapse cam usage!

So, my max FPS is about 16 so far. I am running the USB Camera 0 - > ONR-SS-7618-deeplabv3lite-mobv2-qat-robokit--768x432 at a temperature of about 55C.

The regular settings have been applied with that ONR-SS file.

what are some next steps I can take to perform other functions within this image?
