Linux/DRA726: Video IRQ error message on serial

Part Number: DRA726

Tool/software: Linux

I have been doing some test with some QT app so I needed to mask weston. When weston is not running I get these kind of messages on the serial line
In this case I have not cleared the splash screen yet. When I run weston and then do systemctl stop weston I get a similar message

Do you have any idea what is causing it, if so how to get rid of this?

My splash screen is based on the one from Venkat. I never see that when Weston is running and the splash screen has been removed.

The first message was on boot and the second when I pressed on key on the USB keyboard to get the screen out of blanking mode.

  • can you look at this issue?
  • It appears that if I set it so the screen doesn't try to go blank the problem doesn't appear. I get the error message when the screen goes blank and when I press on a key on the keyboard to get the screen back.

    Michel

  • Michel,

    Could you send us dss register dumps[1] and clock dumps[2] at various stages of your execution? the stages as i understand are

    1. splash screen running, weston in background.
    2. splash screen disabled, weston in foreground.
    3. weston disabled.
    4. QT app launched.

    If I understand correctly, the error is seen in (3) and (4). If the above stages are not correct, please list the correct stages along with your response.

    What does the QT app do? Is it a direct DRM application? If yes, what planes is it using and what is the z order it is configuring?

    thanks and regards,
    Venkat

  • Michel,

    Do you have an update or further questions on the issue you are facing?

    regards,
    Venkat
  • Venkat,

    Like usual I had to deal with a few other emergencies so that was put on hold. I will be getting back to that next week.

    Michel

  • Michel,

    Did you get a chance to relook at this issue?

    regards,
    Venkat
  • Venkat,

    Still working on a customer specific part, will get back to the generic board in a week or two and check that again.

    I went around the problem on dev by disabling the blanking of the display. The problem seems to only appear when the LCD display is turned off.

    I now disable the splash screen in a systemd service for boards which I do not want to run the gui on like my reflash micro SD disk. At manufacturing I use a micro SD device to reflash the board, the software normally boots off the QSPI but at manufacturing I force it to boot of the micro SD.

    It has not been resolved. I do not get the message often

    I will check the registers as you mentioned in another message.

    I have been given higher priority so I didn't do anything special to trigger the problem.

  • Venkat,

    Here is what I get when trying to download the scripts

    The proxy server received an invalid response from an upstream server.
    The proxy server could not handle the request GET /glsdk/util-scripts/blobs/master/debug/dss_clockdumps.sh.
