TMDXEVM3358: About the default image in SDK v07.03.00.005

O.H

Part Number: TMDXEVM3358

Hi experts,

[Basic Information]
Evaluation board:TMDXEVM3358
SDK used: PROCESSOR-SDK-LINUX-AM335X
SDK version:07.03.00.005

[What we did]
After installing the above SDK, run create-sdcard.sh in the bin folder and select "tisdk-default-image-am335x-evm.tar.xz" under "Install pre-built image from SDK". Insert the SD card with the image written into the SD card socket of EVM, and confirmed that it can boot and communicate serially.
 
[Questions]

Q1:Have you found out why matrix-gui-2.0 does not start unless weston is stopped once?

Since matrix-gui-2.0 does not start by default, I sent the command "/etc/init.d/matrix-gui-2.0 start" via serial communication and tried to start gui-matrix-2.0, but it gave me the error message "already started; not starting." and could not start. After checking the forums, I found that restarting weston would start it, so I executed the following commands. I would like to know how to avoid executing the above commands if possible.
/etc/init.d/weston stop
/etc/init.d/weston start
/etc/init.d/matrix-gui-2.0 start

Q2:I would like to evaluate the flick-swipe operation, is there any samples, etc.?

The SD card that came with EVM had a GUI demo for flick-swipe operation, but it does not seem to exist in the default image of this SDK.

Q3:Is it correct to proceed with the following information when running the ubuntu desktop environment on am335x?
https://elinux.org/Beagleboard:Desktops_On_Ubuntu/Debian

At first, we had an image of running an application on Ubuntu desktop environment (GUI), but the SDK is only Yocto based. I found "am335x-evm.dtb" in the following Ubuntu image, so I think it is possible.

Best rgards,

    Hi O.H,

    Re. Q3, as you already see, we don't officially support Debian on AM335x, but if you already have an ARM build Debian root filesystem, you can just populate it into the second partition of the SD card which has the image you flashed from the Processor SDK, but please ensure its "/boot/" and "/lib/modules/" folders are preserved. These folders contain the kernel images.

    I will look into your Q2, but meanwhile I am routing your Q1 to our graphics expert for comments.

    Hello,

    There is a bug with the weston init scripts and by default, two Weston scripts are present in our filesystem and are getting launched simultaneously. Due to which, the weston is launched in a bad state and needs be restarted.  We are working on addressing the issue in our next release.

    Hello,

    I am not sure what swipe app you are looking for but the following directory have a few touch related tests: usr/share/qt5/examples/widgets/touch

    Thank you for your reply. The demo of what we are looking for worked with SDK version 05.02.00.10. The touch demo is shown below.

    As an additional question, the above demo could not be launched with SDKv06.03.00.106 and v07.03.00.00.005. Are these caused by something on the test application side? Or are they related to the Weston issue you previously answered?

    The specific situation is as follows.
    (1) Start matrix-gui-2.0 and the menu appears.
    (2) When the touch test application icon was touched, the screen went dark.
    (3) After a while, the menu of matrix-gui-2.0 is displayed again (loop).
    (In case of SDKv05.02.00.10, the touch test application started normally.)

    Best regards,
    O.H

    Hello,

    The touch demos came from Qt's website and it's not something we implemented. If you still see the source code on Qt's website, you could try to compile it with newer SDK.
